From ea7446ba82b1d4225ae2e462340e529194514768 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Tue, 3 Dec 2019 20:31:24 -0600 Subject: [PATCH] i965/blorp: Don't resolve HiZ unless we're reinterpreting This eliminates 50% of pixels (2M) rendered for a blit in GS:GO. This accounts for 3% of pixels rendered in the game. Total GPU clocks for the first 900 frames of CSGO improves by 1%.
