OptiScaler v0.9

April Foo...

No, wait, almost forgot, this isn't an April Fools joke, that was a close one. What we wanted to say was...
We're back with a new Stable build after 7 months of massive feature creep, prolonged testing and multiple delays (kinda like the AAA game industry, atleast regarding the last part).

Kept you waiting, huh?

❗Our biggest release so far,❗so don't be surprised by the chungus changelog

Lots of people have been asking us over time about supporting the project, and we're finally happy to say that's now possible! Also linked in the Readme

• BMAC ☕
• Github Sponsors ♥️

What comes bundled:

• OptiScaler 0.9-final - Signed build
• Fakenvapi 1.4
• Nukems dlssg_to_fsr3 0.130
• FFX 2.2 SDK - FSR 4.1, FSR-FG 4.0.0
• XeSS 3 SDK (upscaler still reads 2.0.2, MFG is still Arc only❗)

What doesn't come bundled:

• FSR4 INT8
  • which is required for any other non-RDNA4 card!

New and improved MAJOR features in 0.9:

• FG settings received a major rewrite/revamp - added XeFG (+XeLL), Redstone FSR4-FG, separated options into FG Sources and Outputs, added shortcut etc (a big part thanks to @FakeMichau, also @cdozdil)
  • Added enable/disable FG shortcut key - default is End (customisable, Keybinds in Overlay, FGShortcutKey in INI)
  • Some options aren't supported and may be implemented down the line (e.g. XeFG as FG Source, DLSSG as FG Output)
  • HUDless logic improved
  • OptiScaler now comes bundled with latest Fakenvapi (1.4) and Nukems dlssg-to-fsr3 (0.130)
  • FG Inputs (game FG inputs AKA what you select in the game) and FG Outputs (what you want to use through Opti) - you need to select both now
    • DLSSG via SL FG Input is recommended, then FSR-FG then OptiFG/Upscaler as a final resort
  • All of these options explained more in the Wiki in Frame Generation Options

• Updated to XeSS 3.0 SDK (@cdozdil) - yellow XeFG restart text must be followed, otherwise ghosting will be noticeable
  • XeFG doesn't work in exclusive fullscreen. Requires using Borderless Windowed/Borderless Fullscreen/Fullscreen Windowed!
  • Due to how XeFG works, you might need to activate XeFG once and then restart the game for all settings to apply - hence the yellow warning text.
  • Do not use RTSS with Reflex markers injection when using XeFG!
    • For optimal compatibility, also enable Use MS Detours API hooking in RTSS Setup/Settings
  • All XeFG requirements/limitations explained more in the Wiki in Frame Generation Options
  • MFG support officially added (still Arc only❗)
  • Now able to change interpolated frame count on the fly
    • freezes between 2x <-> 3x/4x are expected
  • Extra XeFG checks to prevent crashes with older binaries
• Added XeFG UI Composition option
  • Enabling this option reverts XeFG to previous XeFG 2.0 behaviour where it doesn't try interpolating the HUD - fixes artifacting for transparent HUDs

• Updated to FFX 2.2 SDK (big part thanks to @FakeMichau, also @cdozdil) - FSR 4.1 upscaler, FSR-FG 4.0.0 (ML-FG) (RDNA4 only!!!)
  • 4.0.0 ML-FG doesn't work with Nukems, as that mod only uses FSR3-FG!
    • All of the FSR Redstone features officially support only RDNA4, so unless you're willing to use Linux with FP8-to-FP16 emulation (or AMD decides otherwise), supporting other gens isn't happening. FSR4 INT8 upscaler (4.0.2) is the only version prior gens can use, and you'll have to find it yourself, Opti does not ship it.
  • Switching between FSR3-FG and FSR4-FG is possible while FG is active
  • Fixed model selection on FSR 4.0.3 and FSR 4.1 (thanks to @FakeMichau and @TheRazerMD)
  • Added FSR4 Debug options (@cdozdil) - FSR4 Debug view and FSR4 Watermark (Watermark requires game restart, thanks to @Astyyyyy for fixed WM) as well as FSR4-FG Watermark debug option (MLFI)
  • Updated FG and FSR4 model menu displays (@TheRazerMD)
    • Should make it more clear which FG settings to (not) use for FSR4-FG and what the models represent

• Added FSR4 Vulkan w/Dx12 support (@cdozdil) – FSR3.x/4 VK w/Dx12, as well as FSR 2.1 VK w/Dx12
  • This enables using FSR4 on Vulkan games - works through the DX12 interop, thus the upscaler cost will be noticeably higher
  • IMPORTANT - Linux currently doesn't support FSR3.X/4 VK w/Dx12 due to missing some needed extensions.
• Added RCAS and Output Scaling to Vulkan upscalers (@cdozdil)
• Also updated all downscalers for Output Scaling (@cdozdil)
  • Sharper Bicubic, added Lanczos 2 & 3, added Kaiser 2 & 3
• Added missing Vulkan hooks (@FakeMichau)
  • This fixed NMS VR crash

• Added separate Non-Linear Color Space option for FSR4 (@cdozdil)
• Quirks reorganising and support improvement (@TheRazerMD)
  • WinGDK versions should now also be supported if they stick to the regular filenames
  • Various game quirks added for a better out-of-the-box experience
• General BAT improvements and updated Uninstaller scripts to remove additional files, along with old Opti versions, and unused files (nvapi64.dll etc) (@TheRazerMD)
  • Also added OptiPatcher support to the BAT (thanks to @realdody for the initial commit, and @TheRazerMD for bugfixing and improving afterwards)
  • Another side project of ours - OptiPatcher - an ASI Plugin for OptiScaler for exposing DLSS and DLSS-FG inputs without adapter spoofing in supported games and avoiding any kind of performance overhead.
• OptiFG improvements (@cdozdil)
  • Should stop The Callisto Protocol from crashing with its special heaps spamming
  • CPU usage should now also be reduced
• Removed DlssOverrides folder (@cdozdil)
  • Reg files weren't required for a long time now and have already been integrated into Opti itself
• Autoapplying fixes and quirks for Luma Unreal Engine mod (@cdozdil)
  • Luma UE should now be working properly without any editing (check the Compatibility Entry for preferred method of loading, also the FSR4 list for confirmed working games so far)
  • Should also work fine for Win 10 users (FSR4 still requires AgilitySDK upgrade on Win 10)
• Added VRR FPS limit calculator under Framerate tab to select an optimal framecap (@cdozdil, also @FakeMichau)
• Added Active Quirks info to overlay menus (@cdozdil)
• Allow auto option for menu scale, as well as saving of menu scale 1.0 (@cdozdil)
  • Helps games that cycle from Windowed to Fullscreen on boot and mess with Opti (e.g. MH Wilds)
• Added FSR2 DX11 input support (@cdozdil) - e.g. Trails in the Sky 1st Chapter
• Added FSR2 Vulkan input support (@cdozdil) - e.g. WWZ
• Separated DLSS/DLSSD preset overrides, also added ability to revert back to game's original preset (@cdozdil)
• Added XeSS DX11 inputs (@cdozdil)
• Added Process Filter option (thanks to Schmidts) ...

This build is older than the v0.7.9 release

Changes since 0.7.7-pre9

It's been a while since we've uploaded a public build (2 months now), thanks to a lot happening in the meantime. Lots of code revamping, HUDfix overhauls, FSR4 improvements, UI changes, new features, jobs being busier than usual etc.

Since it incorporates a lot of fixes and additions, we haven't yet been able to test it properly for a Stable 0.7.8 release, things might've fallen through the cracks, so please report if there are new issues.

OptiScaler v0.7.8 (Typeless)

Whoa, it's been almost 4 months since last Stable release? Damn, time does really fly.
Loads has happened in the meantime, and after loooots of code revamping and overhauls and Nightly testings (many thanks to everyone who helped testing!), we're finally ready for 0.7.8 😎

There's a chungus amount of changes, so we'll let the release notes talk for themselves! And no, there's no XeFG DP4a here...yet

We also have another side project - OptiPatcher - an ASI Plugin for OptiScaler to expose DLSS inputs without spoofing in supported games (if you need NukemFG on UE games, that still requires spoofing sadly, for non-UE games, Michau's SL Spoof is pretty successful in unlocking all options).

New and improved MAJOR features in 0.7.8 since 0.7.7-pre9:

Regarding FSR4 models

As best as we can see, models seem to correlate to quality/rendering presets. Internally, AMD seems to be using Model 0 for Native AA, Model 1 for Quality, 2 for Balanced, 3 for Performance. Models 4 and 5 not exactly sure, but 5 should be for UP. Unlike the other models, Model 1 seems to have a bit inconsistent deadzone around ratios, thus in some games Quality actually gets redirected to Model 0 which causes the shimmering noticed in Oblivion and STALKER 2. Hence the reason Optiscaler is always forcing Model 1 for Quality and UQ. AMD know about this issue and will be fixing it in a future update. And to try explaining the model numbers, maybe each higher model has more accumulation history, which would explain why Model 0 is the sharpest (and meant for Native AA), and e.g. Model 2 is blurrier, but also more stable in games (as Balanced) which were forcing Model 0 (instead of 1) on Quality and causing shimmering.

OptiScaler v0.7.7-pre9 (Daria)

Recently, I have been refactoring OptiScaler a bit, and it looks like I moved a lot of code, which caused numerous compatibility issues and bugs. Thanks to @TheRazerMD’s continuous support, we have (hopefully) resolved all of the issues. There may still be some edge cases we missed; please report them with logs as usual.

Changes for v0.7.7

Added

• Added FSR4 support (HUGE thanks to @PotatoOfDoom 🙏🏻)
• Added integration with Nukem's dlssg-to-fsr3 (HUGE thanks to @FakeMichau 🙏🏻)
• Added FSR2 Dx12, FSR3 Dx12, FSR3.1 Dx12 & Vulkan inputs (@cdozdil)

• Added game quirks for No Man's Sky and Minecraft (@cdozdil)
• Added a check to prevent crashes with FMF2 & FSR inputs (thanks to TheRazerMD)
• Added a quirk for RDR1 & updated Cp77 one to disable OptiFG (@cdozdil)

Changed

• Revamped init-flag handling and added buttons to reset values to their defaults (@cdozdil)
• Changed XeSS version-checking method to prevent crashes (@cdozdil)
• Moved FSR FOV and camera values into a collapsible section (thanks to TheRazerMD)

OptiFG is basically a hack, and Hudfix is pushing it even further. We’re aware of its compatibility issues (and crashes). I can’t guarantee I’ll fix all of them, but I will revisit OptiFG soon. Meanwhile, I suggest using Nukem’s mod for any games that support DLSS-G.

OptiScaler v0.7.0-pre66

This build adds experimental Frame Generation support to v0.6.8-pre4 for DLSS & XeSS supported games.
Instability and crashes are possible, so be warned.

Frame Generation will not work if OptiScaler is used as nvngx.dll. Please follow these instructions.

For best results please avoid using overlays like Steam/Epic/RTSS.

pre66

• Fixed more resource tracking issues, HudFix should be much more stable now
• Added auto-fallback to classical FG when hudless can't be captured
• Added Reflex FPS framerate limit slider (thanks to @FakeMichau #108)
• Added freetype font for menu (thanks to @FakeMichau #117)
  
• Added Immediate Capture option for HudFix

; Enables capturing of resources before shader execution.
; Increase hudless capture chances but might cause capturing of unnecessary resources.
; true or false - Default (auto) is false
HUDFixImmadiate=auto

• Added Capture Lists for HudFix, which would help some games (Star Wars: Outlaws etc.)
  

• Fixed issues on loading libxess.dll (thanks to FakeMichau)

• Added option for loading ReShade64.dll

; Loads Reshade64.dll from game's exe folder
; true or false - Default (auto) is false
LoadReshade=auto

• Added crude reimplementation of EndlesslyFlowering's AutoHDR-ReShade ForceHDR and UseHDR10 options, don't forget to use Inverse ToneMapping shaders

; Force HDR color space
; true or false - Default (auto) is false
ForceHDR=auto

; Use HDR10
; true or false - Default (auto) is false
UseHDR10=auto

• Added auto disabling of Epic Overlay when using FSR-FG swapchain

Mini HudFix Guide
Enable debug view and check different limit values:

1. If default settings can't capture hudless go to Step 2, if found hudless but it's not stable go to Step 4
2. Try enabling Immediate and checking again, if still can't capture go to Step 3, if found hudless but it's not stable go to Step 4
3. Try enabling Extendedand checking again, if found hudless but it's not stable go to Step 4
4. Find a spot it's always stable and select Create List wait a bit and then select Use List

pre36

• Added FSR 3.1.2 support
• Fixed spoofed GPU name issue (Thanks to @MapleHinata)
• Fixed RDR crash issue (only with bundled amd_fidelityfx_dx12.dll)
• Fixed XeSS not selectable on Capcom games (Thanks to FakeMichau & BayuPratama)
• Changed to hook dxgi/d3d12/d3d11/vulkan-1 when game loads them. This should increase compatibility with Death Stranding and Capcom games (thanks to Maple)
• Fixed ini reload logic to not overwrite user changed values
• Added resource barrier fixes to FG inputs too (Velocity & Depth, again fixes Death Stranding)
• Added FG Rectangle option for games with black bars (ultra wide etc)
• Added Source Api info to menu (DLSS/XeSS)
• In general tried to improve stability and capture accuracy of Hudfix

UE games might need Limit 2 with this update with pre66 not needed

pre23 added fix for regtangle/noise issue when using HudFix

pre22 re-implemented Extended HudFix option which now works with Control (don't forget to disable Motion Blur + Film Grain).

pre21 should increase compatibility and stability of Hudfix and mod in general.

New Options

Frame Generation

Enables & disables frame generation

Allow Async

Enables & disables async compution for frame generation which improves performance.
It usually cause crashes, so use at your own risk

Debug View

Enables & disables FSR FG debug view. Userful for checking if Hudfix working correctly.

Only Generated

When enabled only FG generated will be shown. Used for debug purposes.

HUD Fix

Enables & disables hudless image capturing.
It might cause crashes

• Limit option delays capturing hudless image for capturing correct image
• Extended option tries to capture more image formats

When hudless image captured correctly you should see it in Debug View. Bottom middle image should not have any HUD elements.

Thanks to Artur, FakeMichau, RazzerBrazzer, BayuPratama and all DLSS2FSR community for helping me on testing this build.

OptiScaler v0.6.8-pre4

This release does not have Frame Generation support

Added

• UseGenericAppIdWithDlss for DLSS preset overriding on games like Monster Hunter Rise (thanks to @MapleHinata) #72
• XeSS inputs support. Now if a game supports XeSS upscaling, OptiScaler can use XeSS inputs instead of DLSS. Sadly, Unreal XeSS Plugin does not provide a depth buffer which leads degraded visual quality.

• FakeNvapi menu support (thanks to @FakeMichau) #81

Fixed

• DirectX 11 FSR 3.1.1 backend crash issue with old VC Runtime versions. (thanks to @MapleHinata) #70 #71
• Prevented using Ultra Quality of preset with real DLSS. (thanks to @MapleHinata) #80
• XeSS inputs were not working with Death Stranding Director's Cut (thanks to BayuPratama)
• Broken DLSS upscaler backend (thanks to @MapleHinata)
• Broken custom nvngx_dlss.dll loading option (thanks to @MapleHinata)
• Broken XeSS 1.2 support (thanks to mayoringram)

OptiScaler v0.6.7

Mistakenly uploaded pre14 as final, if you have downloaded this release before please redownload.

Added

• Native DirectX11 FSR 3.1.1 upscaler backend (thanks to new contributor @MapleHinata)

• FSR 3.1.1 libraries

• FSR 3.1.1 Velocity Factor option to in-game menu and nvngx.ini. Which let's users to control the balance between image stability & blurriness vs shimmering & shaprness. Lower values are more stable but prone to ghosting. Default value is 1.0.

• In-game menu is now always available when OptiScaler is loaded
  

• Simple frame & upscaler time graphics
  

• Disabled spoofing during Vulkan upscaler creation. This might allow non-Nvidia GPUs to use FP16 codepath and gain a bit more performance.

• DXVK detection, now Overlay Menu uses Vulkan API with DXVK
  

• DirectX 11 support for Force Anisotropic Filtering and Mipmap LOD Bias

• Support for latest version of Visual Studio (thanks to FakeMichau)

• FSR 3.1 option for DLSS Enabler generator selection at in-game menu

• DxgiVRAM and SpoofedGPUName spoofing options (thanks to ChemGuy1611)

; Spoof amount of VRAM for DXGI
; Spoofed amount in GBs - Default (auto) is disabled
DxgiVRAM=auto

; Spoofed GPU name
; Default (auto) is NVIDIA GeForce RTX 4090
SpoofedGPUName=auto

• LoadSpecialK option to load SpecialK manually (thanks to DARKERthanDA)

; Loads SpecialK64.dll from game's exe folder
; Please put aa empty SpecialK.dxgi file next to SpecialK64.dll
; to set SpecialK's working mode otherwise it will not be activated
; true or false - Default (auto) is false
LoadSpecialK=auto

Changed

• From now on Overlay Menu is not available for nvngx.dll installations.
• Updated ImGui to v1.91.1 v1.91.2

Fixed

• RCAS was crashing with Typeless textures #46, fixes Space Marine 2 (thanks to LeidenXaXa)
• Possible crashes while using Overlay Menu with RTSS (thanks to Artur)
• Crash when switching to FSR 3.1 from in-game menu (thanks to Melinch & BayuPratama)
• DirectX11 performance regression after upscaler time calculation (thanks to Melinch & BayuPratama)
• A typo at menu #49 (thanks to donizettilorenzo)
• Compability issue with GoW:Ragnarok #53 (thanks to RazzerBrazzer & rigopoui)
• Possible crashes during resolution changes and Alt+Tab (thanks to FakeMichau)
• Menu was not working with Shadow of the Tomb Raider & Rise of the Tomb Raider (thanks to Merlinch)
• Wine detection error (thanks to Lilith)

Removed

• These options are removed:
  • MenuInitDelay
  • HookD3D12
  • HookSLProxy
  • HookFSR3Proxy
  • DisableEarlyHooking
  • DxgiSkipSpoofForUpscalers

Huge thanks to MapleHinata for FSR 3.1.1 DirectX 11 contribution!

Thanks to all DLSS2FSR community for their continous support!
