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?

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.

5500XT + Mesa 20.0.x here, no issues with ACO (and the card in general).

I've only tested it on Vega and older cards but I'm quite impressed.

With aco enabled on assassin's creed origins, with RX 5600 XT latest proprietary driver, I have color artifacts : sometimes, ground and vegetation switch color as a flickering effect. If some one tell me how to record screen in game, I will share it.

Just curious. Why don't you use Mesa? Does it also have the same problem?
