FYI, the ACO compiler has just had a major update. It can now handle Vertex shaders, Plagman just updated us on twitter:



Looking good guys :D

ACO is again ahead for TW3 (built latest master branch):

I didn't test it, but developers write it's mostly beneficial for lower end hardware. With high end CPU you probably won't notice big gains.

Does anyone know how to get 32bit Mesa ACO Working on Ubuntu 19.04, only 64bit seems to work.

Never tried it. Now after switching to Navi card, I'll wait with ACO testing until it will catch up with support.

Here are some of my benchmarks using ACO. No graphics corruption was observed during benchmarking.

Radeon RX 580 in 2020 - 4K and 1800p gaming benchmarks

Radeon RX 550 in 2020 - 1080p and 900p gaming benchmarks

Colors seems to be more saturated with AC0 in these screenshots. Unsure if that's a screenshot artifact? (I also wanted to compare quality, but jpeg makes that difficult, and there seems to be TAA or motion blur at play?)

I don't notice any color difference in the actual tests.

Anyone here using Radeon Navi series? How is the stability on Mesa 19.3.5 + ACO?
Shmerl 26 Mar, 2020
Use 20.0.2 (or Mesa master for games specifically). I don't recommend 19.3.5 for gaming. ACO isn't stable there yet.
