Hi all, I'm running Arch on an Acer Aspire 5610 (Intel® 945PM/GM).
It came with XP installed and some complex 3D games runned smooth.
Then I installed Ubuntu and get 700/800 fps on glxgears.
Now on Archie, glxgears is around 300 fps.
So I suppose that something is not ok, I'm using the "intel" driver and glxinfo says I have direct rendering.
At first glxgears only reached 176 fps but adding some options to the xorg.conf I increased it to 300, anyway, I think I can get better performance, but I don't know how.
Someone has a hint?
Thanks!

I also have an intel 945 on a thinkpad T60. I must say, its performance has been dropping..... I think it dropped after the hotplugging update, or after some driver updates.
(I get half the fps I used to in tremulous, and it doesn't work quite as well with games as other OSs)
anyway, right now I get about 515 fps in glxgears, and with the window maximized, i get 122 fps.

With Linux 2.6.28, GEM (Graphics Execution Manager) Linux finally includes a graphics memory manager. This will manage your graphics memory whether it's on a dedicated card or part of your main memory. By providing a central, common memory manager, GEM enables even ordinary graphics, like the popular and cheap Intel 915 chipset, to run 50% faster. That's a performance boost that anyone can see.

Yeah, I've an Acer 5610-4610 myself, and I've been getting drastically lower performance since upgrading to the new hotplugging packages. With the xorg-server-1.4.2(or so) set, I could get great performance with UrbanTerror(a bit better than XP) and ~2100fps in glxgears(with experimental tweaks), but now I'm lucky to get up to 400fps.
I'm not sure if it's a configuration/package issue on my end, or a development issue, but it's getting to be quite the annoyance to not be able to enjoy my Linux partition like I used to.

It's a driver issue, hopefully it will be fixed in the near future (Kernel 2.6.29 + tilling support for pre GM 965 chipsets - After those things are released/introduced things will get much better).
Ubuntu works fine with older intel cards, cause it uses old packages, without GEM or KMS (which are currently setting in)
EDIT:
It seems tilling support has gone upstream, explore this thread for details. With the newer packages you should get at least twice better performance.

Sorry, I'm acting noobish, but I need some clarification:
This new tiling support is for kernel-2.6.28.x or the RC5 kernel-2.6.29?
