OFXR 0.3.3 NIGHTLY RELEASE (v994)

Radeon users

This nightly is for feedback from Radeon users trying OptiScaler and/or RIFE.
I tested the OptiScaler path on my NVIDIA GPU, using FSR 3.1 upscaling through
DLSS inputs. That is what I can verify on my own hardware.

Please test FSR 3.1 first. If it works, try switching to FSR 4. Availability
of FSR 4 depends on your GPU and driver.

The experimental Radeon Vulkan RIFE installer is included. Early tests
suggest RIFE can be demanding on Radeon, so I recommend testing OptiScaler
with Hybrid or FSR frame generation first.

Setup

1. Install the complete, unmodified OptiScaler nightly-20261112 package
   in the game folder. Use winmm.dll for Luke Ross or MSFS2024 and dxgi.dll for UEVR games.
2. Replace the game's OptiScaler.ini with the file included in this ZIP.
   It selects the FSR upscaling backend and disables OptiScaler's own framegen.
3. Open OptiScaler's menu and select FSR 3.1 by name for the first test.
   Its version index varies with GPU/driver, so the supplied INI does not force
   a fixed index. After a successful test, try FSR 4 if it is available.
4. Start the OFXR tray, then launch the game. Select DLSS in the game so
   OptiScaler receives its inputs; OptiScaler performs the FSR upscaling.
5. Start with Hybrid + FidelityFX optical flow or FSR framegen in OFXR.

Frame generation is provided by OFXR. Keep OptiScaler's own framegen disabled.
On Radeon, NVIDIA OFA engines (including the NVIDIA Hybrid variants) and DLSS-G
are greyed out. Old profiles using them are constrained to compatible FidelityFX
routes, and automatic tests omit these unavailable NVIDIA routes.

For Radeon RIFE, use RIFE -> Reinstall RIFE -> AMD Radeon - Vulkan
(experimental), or Install-RIFE-Vulkan.cmd from this ZIP. Prepare Vulkan
for found games from the tray before testing when possible.

Games checked through OptiScaler on NVIDIA

• Ghost of Tsushima: Luke Ross OSR/AFW and AER frame generation.
• Microsoft Flight Simulator 2024: standard Hybrid and FSR frame generation.
• Ghostwire Tokyo UEVR both native stereo with FG and alternate with AER FG

Let me know how it goes. If something fails, please include your GPU model,
driver version, selected upscaler, OFXR logs and OptiScaler.log.

Other fixes (also for NVIDIA)

• OFXR menu with ReShade: fixed device identity checks that could prevent
  the menu from appearing, including the MSFS2024 + DLSS Ghost Fix setup.
• ReShade/DXGI compatibility: added protection against the internal
  D3D11-on-12 adapter crash when global OpenXR ReShade loads late with OptiScaler.
• RIFE installer: fixed transient activation/rename locks that could block
  installation or recovery, and added bounded lock diagnostics.
• VRAM: reduced output-buffer memory use for compatible native OFXR/Hybrid
  3x/4x routes.
• Neural Rendering: fixed pre-SR operation with padded DLSS output textures.
• 3x/4x framegen: restored compatible native OpenXR routes, including VDXR,
  with correct delivery, Fast-mode output capacity and multiplier reporting.
• Native Pimax delivery: isolated the binding queue from pending game work.
• Stereo guides: handled compatible rounded/padded packed-stereo inputs
  while preserving the right-eye boundary and rejecting ambiguous matches.
• OSR-only: fixed capture/admission when FSR was selected but framegen was off.
