The output and scene patch sets make the game read its output, swapchain and scene sizes from the patch page (MacNativeGames' sites for 1.2.1 and 1.4.3); resolution.c picks them from TOTK_OUTPUT_RES and TOTK_RENDER_SCALE and grows the HeapDef texture heap, its parent and the application pool to match. vk_fsr.c runs AMD FSR 1 EASU and RCAS on the present when the window is larger than the game's output (TOTK_UPSCALER, TOTK_SHARPNESS).
