Bug ID: 86165 Summary: [RV770] [bisected] Bad textures rendering on Serious Sam 3 with sb enabled Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: b.bellec@gmail.com
Created attachment 109297 --> https://bugs.freedesktop.org/attachment.cgi?id=109297&action=edit SS3 ground textures at high settings when SB is enabled
Ground textures in Serious Sam 3 are incorrectly rendered (see the first attachment for a preview).
This only occurs with my RV770, not with my HD5850 (Evergreen). This only occurs when sb is enabled (which is the default setting).
The first bad commit is : commit: 7ae9cc71f097af5ae1f83f77f75de2198849faca summary: st/mesa: use new float comparison opcodes if native integers are supported author: Roland Scheidegger sroland@vmware.com date of commit: 2013-08-15 15:30:07 (GMT)

I noted that at low settings, a recent commit broken more dramatically the ground textures, see attachment for a preview.
