From 02db2363f0f9174ecd8b3484c186b250c2a1259a Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Wed, 18 Apr 2018 14:34:55 +0200 Subject: [PATCH] radv: reset the image's predicate after a color decompression pass After performing a fast-clear eliminate, a FMASK decompress, or a DCC decompress, we can reset the predicate to FALSE. With that, the GPU should be able to skip unnecessary color decompression passes.
