If you have a 'true' Ge4 (ti4200,ti4400,ti4600) you're probably better off trying the brand new 28.90 detonators ... the ones with Ge4 enhancements in mind.
[Edit] Added link, there's some newer, fishy looking ones I'm not touching with a ten foot pole - these ones I know have been extensively tested, work, and report improvements with Ge4.
uh...from what i remember, isnt it MEANT to look that screwed up? isnt that the whole point of the alternate view modes, that they're screwed and you should use normal to look at the scenery?
I didn't see a problem either (I.E if it's changed from Ge4, maybe it's using effects you didn't previously have in your old vid card) but stuff those new dets in anyway the common opinion seems to be that they boost performance
