Hi Marek This patch series is Tested-by: Edmondo Tommasina <edmondo.tommas...@gmail.com>
The performance of The Talos Principle benchmark has increased a bit on my configuration (RX 470). I repeated the test about 8 times and it was always better with your patches. Before: 36.5 FPS After: 36.8 FPS Other games tested: - The Witcher 2 - Two Worlds Thanks edmondo On Wed, Nov 16, 2016 at 7:38 PM, Marek Olšák <mar...@gmail.com> wrote: > Hi, > > Patches 1-10 are random improvements. > > Patches 11-14 are cleanups. > > Patches 15-20 add support for optimized shader variants compiled > asynchronously (without stalling rendering). > > The following optimizations are implemented for the shader variants: > - If user clipping is disabled, clip distances and the gl_ClipVertex > code is removed from vertex shaders. > - All VS outputs not read by a PS are removed.
