Games runs slow as normal user, but fast as root user

My problem: When i use a game like q3, ut or mame, if i log on as root the game runs fast, but if i log on as normal user, the game run slow. I configured DRI in X (XFree 4.4) and the console messages displayed when i run the game seems to ok (DRI is being used).

My system:
Intel Celeron 900, 256MB RAM
Sis 305 32MB graphics (PCI)
Linux 2.4.22
Sis_Fb in kernel
Sis DRM updated and loaded
Latest for XFree 4.4
Permissions set to 0666 for DRI in XF86Config.

I tried to see if the problem is the user that starts the game, but if i do a "su" in a xterm the problem remains. Only log on in a tty and do "startx" as root works ok.

Thanks in advance.

PD: Sorry, my english is too bad :P

differ for root and normal users?

No, glxinfo dump the same for root and for normal users. :cry:

Another observation:
glxgears as root : 85 FPS in 5 sec smooth, 0 lag.
glxgears as normal user: 50 FPS in 5 sec, lag every 1 second approx.
