Summary: r600g/evergreen: Incorrect rendering of some effects in doom3 Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: ptpzz@yandex.ru
Created an attachment (id=47801) --> (https://bugs.freedesktop.org/attachment.cgi?id=47801) screenshot of fire rendering
Some doom3 effects like slightly warped objects behind the fire and glass windows aren't rendered correctly on evergreen with r600g (high quality effects should be enabled in the game settings to reproduce). It was not very noticeable before the commit d1b8f8e8b3b41ab6092fa3f18a4891a0198f64de "r600g: don't lookup a vs semantic for position/face", but after that commit it is much more visible.

No, rendering of the effects is not changed with that patch. The only change afaics is the huge performance drop (2-8x) even in the game menu.

--- Comment #5 from Vadim ptpzz@yandex.ru 2011-06-10 15:10:48 PDT --- BTW, If you don't have the game then there is linux doom3 demo (460mb) available to download from idsoftware ftp site - ftp://ftp.idsoftware.com/idstuff/doom3/linux/doom3-linux-1.1.1286-demo.x86.run -but it was very slow download when i tried it, so you would probably want to find it somewhere else to download faster. This issue is reproducible with the demo too.
Also, I don't know if it would help, but IIRR there were shader sources with descriptive filenames and comments somewhere in the pk4 data files (probably pak000.pk4 in the full game, and in the demo there is only one pk4 file. pk4 files are zip archives).
