From a41e2e9cf5f865f21e32cac2ed2e25dd21a05119 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Thu, 26 Oct 2017 18:03:24 +0200 Subject: radv: allow to use a compute shader for resetting the query pool Serious Sam Fusion 2017 uses a huge number of occlusion queries, and the allocated query pool buffer is greater than 4096 bytes. This slightly improves performance (tested in Ultra) from 117.2 FPS to 119.7 FPS (~+2%) on my RX480. This also improves Talos, from 69 FPS to 72/73 FPS (~+5%).
