Valve's ACO Helps Put New Life Into Radeon GCN 1.0 GPUs With ~9% Better Linux Gaming Performance

Great stuff, I wonder how it is for GCN 1.1 GPUs

yeah! What about the immortal R9-290X/390X ?

Michael Batman should be fixed by https://gitlab.freedesktop.org/mesa/...1eb6a22e354a71 . The fix will be in Mesa 20.0.

And the 290!

Out of curiosity, what exactly is the bottleneck that ACO reduces? Since it's a compiler, I imagine it would be reducing CPU usage, in which case I don't think it really matters what GPU you use, so long as it is compatible.

It's a bit of both IIRC - less CPU time when compiling, and the generated shader code is a bit more efficient (less GPU time) when executing.
