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

Among many other Valve ACO back-end improvements for Mesa 20.0, one of the notable additions is this AMDGPU LLVM alternative now working for Radeon "Southern Islands" / GCN 1.0 graphics cards. With this, these original AMD GCN graphics cards may have some extra life out of Linux gaming boxes thanks to slightly higher performance some eight years after these graphics cards first launched in the Radeon HD 7000 series.

been using ACO on my 2400G with good results so far, IMO the biggest change is how it reduces stutter in DXVK games

I appreciate these devs taking the time to support GCN 1.0 hardware that is still in use. It seems a Mutiny was not required to bring this Bounty to Pitcairn after all.

Love it. Linux is great for getting more life out of older hardware. Optimizations for stuff a few generations old is always welcome.

Now enable fsync and see the result

Wow, good job to the folks at Valve. The spread between the longest and shortest frame is less than half a percent.

Now enable fsync and see the result

What does fsync have to do with anything? You mean vsync?

Hmm, that doesn't seem to be the same thing as the existing use of the name "fsync". I bet I'm not the only one confused by that.

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