From 901f57dff543f89c03c9e1e4eb4bdd79c16cbeb7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Tue, 3 May 2016 12:29:16 +0200 Subject: [PATCH] radeonsi: set DECOMPRESS_Z_ON_FLUSH if nr_samples >= 4 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Vulkan always sets this. It only affects in-place Z decompression. This is recommended for performance, but what app uses MSAA depth texturing?
