All of the changes below are for BGProxy.

• Fixed input issues introduced in the previous update. The mouse cursor should now work in Dishonored and other Unreal games again.

• Fixed some minor render issues.

You can now make games think you have a different graphics card. Some games won't launch or will disable features if they don't recognize your GPU; this gets around that. Add a \[Spoof] section to your bgproxy.ini (details below).

• OpenGL games now present through a DirectX 12 pipeline. Best case is zero-copy via a shared texture, otherwise it falls back to async or synchronous readback depending on driver support.

• OpenGL contexts are automatically upgraded to the highest compatibility profile your driver supports, which lets the driver apply more optimizations while keeping legacy rendering working.

• Frame latency waitable is now waited on before rendering instead of after, which fixes cases where the game could start drawing before a back buffer was available.

All on by default, no config needed.

• Games using Windows wait timers get ~0.1ms precision instead of the default 1–16ms. Needs Windows 10 1803+.

• Old multimedia timer calls are also upgraded to Windows 10 high precision timers.

• Some games sleep their render thread between frames, which causes micro-stutter. BGProxy now intercepts these fix them.

• Device loss now logs the specific HRESULT from GetDeviceRemovedReason.

• Proxy DLLs set a window property identifying which proxy type is loaded, so external tools can check without inspecting the file.

Place a file called bgproxy.ini in the same folder as the proxy DLL. If you don't create one, defaults are used.

Makes the game see a different GPU. Only fill in what you need to change.

• All games now continue rendering and playing audio when alt-tabbed.

• Keyboard and mouse input is blocked while the game is in the background, so you can type in other apps without affecting the game. Gamepad input still passes through.

Tabbing back into a game no longer leaves keys in a pressed state.

• Fixed crashes on startup for Yakuza 0, Metro 2033, Fallout: New Vegas, and others.

• Fixed the "wavy" / shimmering motion artifact at native resolution in Dishonored.

• Anti-aliasing and color accuracy are now preserved in games that use MSAA or sRGB when using flip model presentation.

Major performance improvement for OpenGL games (KOTOR, StarStable Online, etc.) — rendering no longer goes through the CPU.

Previously, the installer only checked for graphics DLLs through static PE import analysis. Engines like Unity and Unreal load D3D and OpenGL dynamically rather than through static imports, so the analyzer would find no available proxies for these games. The installer now properly supports these engines. This means the correct proxy is detected and offered automatically, even for engines that load their graphics APIs at runtime.
