Summary: ETQW: Enabling "Soft Particles" causes major performance issue Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: sa@whiz.se
Enabling the option "Soft Particles" in the game Enemy Territory Quake Wars causes a major performance drop to ~ 1 fps, CPU goes to 100% so I'm guessing some sort of software fallback is hit?
Options → Settings → Advanced → Soft Particles
I'll see if r300g has the same problem, if so it's probably a more general problem.

--- Comment #4 from almos aaalmosss@gmail.com 2012-01-15 12:53:47 PST --- Now I tried it with mesa master on a barts pro, and soft particles don't cause any noticeable slowdown.
