Description

Details

• Mesa (git) with Valve's ACO shader compiler, also built with LTO and LLVM (git)
• ACO Details
• ACO testing instructions
• daniel-schuermann/mesa
• Project forked from gloriouseggroll/mesa-git and quickly modified to use an ACO-patched Mesa source instead

Information

• Provides an alternate Mesa shader compiler (named ACO) with notably improved shader compile times (compared to the default LLVM shader compiler)
• Currently only supports RADV (so AMD GPUs that support Vulkan)
• Can benefit native Vulkan games, and games ran under Wine via DXVK or D9VK

Improvements:

• Notably improves shader compile times and overall experience with Guild Wars 2 and D9VK
• Seemingly slightly improves average FPS with FFXIV and DXVK

Updates

• This repo will likely receive updates at random periods until I either lose interest, someone else maintains a repo better, or ACO is implemented upstream
• If an exciting commit is pushed and you want an update, feel free to contact me

• If using GNOME on Wayland at all, see gloriouseggroll/mutter and add it as well, or alternatively only use Xorg and disable Wayland being used on the log-in screen/GDM

• Update Mesa packages:

sudo dnf update

Verifying

• Look in Terminal for this line after starting anything that uses Vulkan:

WARNING: Experimental compiler backend enabled. Here be dragons! Incorrect rendering, GPU hangs and/or resets are likely

• Look at vulkaninfo for mention of ACO:

vulkaninfo | grep 'AMD RADV/ACO'

• Use DXVK's HUD environment variable (for both DXVK and D9VK) to check for mention of ACO:

DXVK_HUD='full'

Troubleshooting

• Temporarily disable ACO and use LLVM with an environment variable:

RADV_PERFTEST=llvm

Uninstall

• Remove this repo's GPG key:

sudo rpm -e 'gpg-pubkey-716644b8-5d1d6307'

• Remove this repo:

sudo rm -v '/etc/yum.repos.d/espionage724-mesa-git-acotest.repo'

• Switch this repo's installed Mesa-related packages to either standard Fedora packages or another repo's:

sudo dnf distro-sync
