Dota 2 at 1080p is CPU bound on newer hardware, but for those curious if the performance is sufficient for older cards like the R7 260X or HD 7950, here are those results...

Yep, Dota 2 with Vulkan at 1080p still runs great on the GCN 1.0/1.1 era hardware with the RADV Vulkan driver when using the AMDGPU kernel driver. The only RADV situation running into problems with Dota 2 was the R9 285 "Tonga" being unstable for this particular game but working fine for the other tested Vulkan games.

Dota 2 being rendered by Vulkan at 4K saw the GTX 1060 running a few frames ahead of the RX 580. The RX Vega cards were running shy of the GTX 1070, likely due to more optimizations still needed for GFX9/Vega hardware with the RADV driver. At least Vega on RADV is doing much better than we saw months ago.

If wanting to play Dawn of War III with low quality settings at 1080p, the RX 560 / HD 7950 hit around the bare minimal point for being playable. In this configuration the RX Vega performance was still coming up short of the GTX 1070 -- and the GTX 980 Ti too in this scenario.
