The Render Path

WSA routes Android's OpenGL/Vulkan through ANGLE to your host GPU via Direct3D. When the GPU is unavailable it falls back to llvmpipe software rendering — usable for simple apps, painful for games.

Fixing Glitches

Update GPU drivers (NVIDIA / AMD / Intel)
Restart WSA after a driver change
Enable 'Force GPU' properties if your build supports them
On black screen, test with software rendering to isolate the cause

Heavy 3D games may never be smooth under translation. For those, a native emulator or cloud streaming is a better fit than WSA.

ARM Translation Note

Graphics calls from translated ARM libraries add overhead. On ARM Windows PCs this is less of an issue; on x86 it's the main source of lag in GPU-heavy apps.
