AMD Radeon Linux Gaming Performance On Mesa 20.1 Looking Good With RADV+ACO

The Linux-native Shadow of the Tomb Raider was one of the few cases where ACO wasn't helping to boost the overall performance.

Strange Brigade, a Vulkan-native Windows game running on Steam Play, was seeing real nice improvements on all but the Navi graphics card when enabling ACO. The Navi/GFX10 ACO support continues to be improved with time.

Thrones of Britannia saw better performance mainly out of the RX Vega 56 graphics card when flipping on ACO. But overall we are quite pleased with how RADV+ACO is shaping up for Mesa 20.1-devel. There still is room for improvement with Navi but overall ACO has matured quite well in recent months and will be interesting to see if later Mesa 20.x releases decide to enable ACO by default and if we end up seeing ACO ported to RadeonSI as has been discussed in the past.

Those wanting to try out RADV with ACO can enable it on Mesa 20.0+ with the RADV_PERFTEST=aco environment variable. Mesa 20.1 stable should debut around the end of May.
