A in-game screenshot without any anti-aliasing method active.
MSAA looks just ugly (not like anti-aliasing should look like) and Oil Rush
spams "OpenGL error: invalid operation", MLAA doesn't seem to do anything and
FXAA just gives a white screen.
All anti-aliasing methods where tested with Oil Rush.
Exact settings:
MSAA: 8x, setted from the game launcher.
FXAA: Setted from the game launcher.
MLAA: 32x (for both, 2D and 3D) forced by drirc.

Sorry for setting the wrong mime type for the images, they are png images. If you need me to re-attach just tell. :)

Forcing MLAA through driconf on Cayman 6950 crashes Gnome Shell if both mlaa and mlaa color (2D) are set (tested with both set to 8). If one of them is not set, Gnome Shell doesn't crashes. MLAA color (2D) seems to have an effect on my Gnome Shell display.
Should differents anti-aliasing methods be tracked in differents bugs?

(In reply to comment #6) > Should differents anti-aliasing methods be tracked in differents bugs? Yes. MSAA is the only one that's part of the driver pipeline. MLAA is post processing effect.

Is this still an issue with mesa from git? There were some recent fixes for MSAA on cayman.
(In reply to comment #8) > Is this still an issue with mesa from git? There were some recent fixes for > MSAA on cayman. I used fglrx for some time now cause of other bugs, but now I'm on mesa again (10.0). Right now MSAA doesn't seem to do anything at all. I didn't test other anti-aliasing methods for now, but you told to track them in different bugs anyway. Should I still try latest mesa from git?
It could be a bug in the game. Does MSAA work in other games?<=

(In reply to comment #10) > Does MSAA work in other games? I tested: - Oil Rush - Left 4 Dead 2 - Garry's mod - Worms Reloaded - Portal - Team Fortress 2 - Serious Sam 3 - Kerbal Space Program - Killing Floor and maybe other games I don't remember right now.
First of all, I'm only interested in MSAA. In addition to testing Catalyst, is it also any better with current Mesa master?

Removed MLAA from the topic since it was covered, tested and fixed in bug 64695.
(In reply to comment #12) > Is it any better with Catalyst? Yes. With catalyst the FPS goes down while the scene looks anti-aliased. With r600g the FPS and the scene stay the same. (In reply to comment #13) > is it also any better with current Mesa > master? I would love to answer you that question but master is currently a crash party for me (3 of 4 tested games crashed at launch, with the one that worked it's really hard to tell if anti-aliasing is working. So my only answer right now can be a "maybe"). I might have to investigate more into this later and open a new bug report. (In reply to comment #14) > Created attachment 90778 [details] [review] [review] > sRGB fix > > Also, does this patch for Mesa improve MSAA? Yes! But there are new bugs with it (tested with gary's mod: Colors are generally darker, sometimes when looking at some things they get even more dark. But screenshots look normal. Should I open a new bug report for it or is that already known/fixed?).
