Summary: [regression glsl r300g] Heroes of Newerth slowdown after glsl2 merge Product: Mesa Version: git Platform: Other URL: http://www.heroesofnewerth.com/download.php OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: sa@whiz.se

The game Heroes of Newerth (reproducible in the menu with the client) is slow as molasses after the glsl2 merge.

Both the game itself, and normal procedures in X while the game is running (e.g. moving windows around) is noticeably laggy. CPU usage is still low, so I guess something is keeping the GPU busy?

This bug have not been bisected, only confirmed by trying the commit immediately before the merge (15a3b42e) which is fine, and the commit with the glsl2 merge (6c03c57) where the problem is apparent.

This is most likely the same slowdown I noticed in the game Savage 2 (bug 28517) but I'm filing this separately to be sure.
