- The pacing thread aims each immersive window eye through the window itself (AimEyesThroughWindow): it keeps its position but looks square-on at the window's plane through an off-axis frustum just around it, so the eye image is the window, at the display's pixel density (about 680x380 per eye at render_scale 0.8 instead of 1344x1408), with a two-pixel border the mask leaves transparent. The frame's views carry that pose and field of view to the projection layer. - vulkan_interop.cpp copies an eye smaller than its AHardwareBuffer into the buffer's corner, and the Quest layer's imageRect is the rendered part of the swapchain image. - These eyes are not foveated: their field of view follows the head, which would rebuild the density map every frame. - Quest only (kWindowShapedEyesSupported); the PC backends copy whole eyes and keep masking them. debug.wiicompiled.window_eyes 0 renders them whole and masked again for A/B timing. - Quest 3, paused Retro Rewind race, render_scale 1.0: Immersive window runs the GPU at level 1 (456 MHz, app GPU 11.0 ms, eyes 8.4 ms) where Immersive needs level 3 (599-640 MHz, 13.4 ms, 10.3 ms), about 42% fewer GPU cycles. No edge artifacts, image as sharp. Docs: OPENXR.md. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
