From: Bas Nieuwenhuizen Date: Tue, 25 Sep 2018 10:00:41 +0000 (+0200) Subject: radv: Do not use multiple draws for multisample copies. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0207ebcbf123a6b230715370459d5f2a48b9fe15;p=mesa.git radv: Do not use multiple draws for multisample copies. Use sample rate shading instead, should give better locality. Makes Nier with 8x msaa on a Raven go 5 fps -> 7 fps in the menu.
