New G5 just arrived last night.

Didn't have time to do much with it yet, but I did give Q3 a quick run and timedemo. And, I noticed an odd problem.
The Q3 screen isn't centered. In fact, I'm missing a good chunk of the left part of the screen. And the right side of the screen is just black - as if it's not getting drawn. If I go to the multiplayer menu, the back button is half gone. It's just says, ck...

I tried the ol' get rid of the config file thing, but no difference. The OS screen is just fine. So it's not the monitor setting.
Anyway I can center this puppy again?
Thanks,
Shrapnel
BTW, I use some fairly low res settings for q3, including vertex instead of lightmap and 640x480 - becuase I was originally running on an old 450mhz G4. But here's some general timedemo four numbers with that config...
450mhz G4 - about 60 fps. (as I recall)
450hmz G4 after I upgraded the processor to a 1.4Ghz in the same box - aprox 110 fps.
Brand spankin' new Quad G5 - 400+fps.
Quad G5 with r_smp 1 - 600+fps.
Even though timedemo four gave me 110 fps on my 1.4Ghz G4, my real fps in games would sometimes drop to 30 (or below in certain areas of some maps or during heavy fighting) and would avg around 60-70. So I'm lookin' forward to trying some on-line play with this new comp

Also looking forward to making iPod movies that don't take about 8x real time to encode.
