Radeon RADV "ACO" Performance On Mesa 19.3 Looking Good

DiRT Rally 2.0 is one of the Steam Play tests with DXVK. Here is some odd behavior with the RX 580 outperforming the Radeon RX Vega 56, but at least on the two Vega cards tested, there were measurable improvements to be found from enabling ACO. In the case of the Radeon VII, the performance went up by just under 10% for this racing game.

Rise of the Tomb Raider was seeing nice gains across all three graphics cards even with low quality settings.

With high quality settings, Rise of the Tomb Raider was still seeing better performance with ACO albeit not as significant gains.
