DOOM: The Dark Ages — 268 fps

DOOM: The Dark Ages at Ultra Nightmare with FSR Quality on Linux, 268 fps with afmf-linux

Settings: Ultra Nightmare, FSR Quality. Native Vulkan (id Tech 8), Proton-GE. Two things specific to this game: rtcps crashes RADV’s ray tracing pipeline compiler here, so it is left out; and the engine aborts above 8 swapchain images, so AFMF_EXTRA_IMAGES stays at its default.

About the common part

AFMF_ENABLE=1 AFMF_SEARCH_MODE=high AFMF_FAST_MOTION_RESPONSE=repeat is the layer with AMD’s “high” search preset; AFMF_PACING=0 is a personal choice (no hold on the real frame), leave it out for the evenly spaced cadence. PROTON_ENABLE_WAYLAND=1 DXVK_HDR=1 give Wine’s Wayland driver and HDR; PROTON_FSR4_UPGRADE=1 PROTON_MLFG_UPGRADE=1 FSR 4 in games that ship FSR 3.1; MESA_VK_WSI_PRESENT_MODE=mailbox removes vsync throttling; game-performance is CachyOS’s performance wrapper (gamemoderun elsewhere, or nothing); the rest is Proton housekeeping. With two AMD GPUs, MESA_VK_DEVICE_SELECT='1002:7550!' DXVK_FILTER_DEVICE_NAME='9070' pins the game to the 9070 XT. All the variables of the layer: configuration.
