From 3f55425ee69dafb5d5dd10bea4cf2010d87d5eee Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 5 Sep 2018 09:48:35 -0600 Subject: [PATCH] svga: enable MSAA for SM4_1 device The SVGA device is deprecating the DX9 MSAA support. This patch enables MSAA for SM4_1 device by explicitly setting the SVGA3D_SURFACE_MULTISAMPLE bit. For SM4_1 device, only 4 samples is supported.
