Intel 945GM and 3d acceleration

I have been trying to get this to work properly and am stuck.

I have an Intel 945GM video adapter on my notebook. However, I am unable to play games like astromenace, bzflag due to choppiness in graphics.

I am using the i810 module, have dri enabled.

$ glxgears
4706 frames in 5.0 seconds = 941.112 FPS
4867 frames in 5.0 seconds = 973.330 FPS
4878 frames in 5.0 seconds = 975.427 FPS
4865 frames in 5.0 seconds = 972.904 FPS
4775 frames in 5.0 seconds = 954.941 FPS
4862 frames in 5.0 seconds = 972.388 FPS
4864 frames in 5.0 seconds = 972.644 FPS
4864 frames in 5.0 seconds = 972.782 FPS
4857 frames in 5.0 seconds = 971.243 FPS

$ glxinfo | grep direct
direct rendering: Yes

However, in astromenace, I only get around 7 fps on the intro screen.
Bzflag is unplayable. I did install it in windows on the same laptop and it runs fine.

I run my screen at 1280x800 in 24 bit depth.

I set the VideoRam in my xconfig to 128MB, because from what I have read, this video adapter doesn't have onboard memory, it borrows from system memory, and by default grabs a small amount.

Well, it's an intel card. And the drivers suck almost as much as the card. So, yeah, your stuck. It's probably not going to be playable this century.

I have the same chipset in this laptop, I just installed bzflag and it ran flawlessly with default settings. The only difference that I know of in our setups is I am using the newer "intel" driver instead of "i810".

Wink i personally suggest to install Pclinux or Sabayon to get the best video performances

the 945gm in a Philips notebook works perfectly for me with Pclinux 2007 and Sabayon 3.4,in Suse it is slower and has worse performances with the new intel driver,i had to edit xorg to use the older intel and anyway it still worked worse than in Pclinux or Sabayon ,in Mandriva and Fedora works better then suse but not as good as it's a problem related also to how the distro manages the video driver.
i personally suggest to install Pclinux or Sabayon to get the best video performances possible,now i use it with Pclinux and works perfectly !

P.S.:the biggest onboard video ram possible is 224-i know it's a strange number-and not 128 mb

Good Luck
