What? System slowdown with >128MB? That sounds weird to say the least! But check this out: When I o/c the V3 over 183MHz the system remains stable but the performance begins to drop in 3DMark... I might have to take a moment here...

Anyway, the games fly except Outcast, with 5 fps even with the minimal detail and poorest resolution. I don't get it. It's totally unplayable, like Quake on C64 or something...
