Hello everyone. I have an intel gma 950 video card and I think it's not performing as it should.
From what I've read here at the forums, this card should be getting ~1200 FPS in glxgears (a couple of owners of this same card reported that). Mine is getting about ~750.
I really don't know how to tweak my xorg.conf anymore so please help me. Maybe the owners of said video card could let me see their xorg.conf ?
Here's mine:

glxgears isn't a benchmarking tool, actually. Try running:
glxinfo | grep direct
If that returns:
direct rendering: Yes
Then you should be fine.
Maybe you can get some more FPS on glxgears by disabling TripleBuffer or the Composite extension, but I'm not really sure about that. Also, you can shrink the window, that should give you extra performance.

Hmm, triple buffer doesn't seem to make a difference because enabling it was the last thing I tried, but no matter what I do, my FPS stays at ~750.....isn't that strange ? I know I've seen several posts here from Intel gma 950 owners that they get around ~1200 FPS.....
Although,
glxinfo | grep direct
does return
direct rendering: Yes
.
Thanks for the response anyway....
EDIT: Just tried disabling triple buffer and the composite extension, and glxgears still returns the same result! I just don't get it

Really, glxgears is not a benchmarking tool. However, it can be used to verify that your hardware acceleration support is working correctly (and it seems that yours is working).
And probably I was wrong about the trible buffer and composite extension. I don't know if there are any flags (or something) that can improve your performance on your video card.
If you really want to benchmark, you should try quake3's time demo or something else.

Ok, here's some benchmarking: If I have xcompmgr running some applications (namely video players) crash with a "BadAlloc (not enough resources)" error..... is that supposed to happen ? Isn't xcompmgr lightweight ?

945gma here.
I've noticed little sluggish 2d performance (ex: moving windows on the screen, switching tabs in konversation, etc) after upgrading to new mesa (7.0.3rc1),libgl,xorg-server,xf86-video-intel.
quake3 works fine though.
Could this be related to your experience?
PS: I get 800+ in glxgears

I always keep my packages up to date. The funny thing is this - I have switched the driver from "intel" to "i810" and I so far have noticed absolutely no difference whatsoever. It's not slower nor faster it's the SAME. How do you explain that ? Now don't go telling me "intel" isn't supposed to perform better than the discontinued "i810"....

As far as I know, 'intel' simply picks up where 'i810' left off, since i810 is no longer maintained..
