Ok, couple things about the two systems ive tried using for vendetta recently

PowerMac G4,
Geforce4 TI, 32meg
1 Gig ram
OS 10.3.4

PowerBook G4 12"
Geforce 32meg video
256 meg ram
OS 10.3.5

Initally(and I think I posted on this a bit back) the powerbook would not run vendetta. I could download it, start it up, and then I would just get a black screen, then in vendetta 3.4, I could play on the powerbook. Now, with the 3.5 series, I get a revert to a black screen when I click play vendetta from the updater. Any Thoughts?

The PowerMac has not had any problems.

im gonna say is the 256meg ram....

I have very similar PBs and it runs just fine. On the 12" you should disable doshaders. After all the updater problems, reinstalling vendetta from scratch would be a good idea, too.

Vendetta runs just fine on a B&W G3/350 with 128(my first machine that i was using for vendetta)

clean install on the powerbook(after all the updated problems)
