Deferred Flushes Land For Radeon Gallium3D, Offering Better Performance

Written by Michael Larabel in Radeon on 10 August 2016 at 08:13 AM EDT. 7 Comments

The patches written about last week for using unflushed fences for deferred flushes has now landed within the Radeon Gallium3D code. Performance win!

The patches are what allow for 23%+ speed improvements for BioShock Infinite. The newly-landed patches will make the performance paired with the AMDGPU kernel driver at least 23% faster while those using the older Radeon DRM driver on kernel-side will see even larger gains. Other ported Linux games may also see performance boosts outside of BioShock Infinite; Feral Interactive their other ports may win too.

The code is now in Git. Time for some new benchmarks today/tomorrow!
