Benq ixtreme 1.5 still has texture popup problems in gta 4 but on a positive note assissins creed is ok now.
I have texture problems in gta 4 pretty bad ,saints row 1,2 not as bad, and a couple movies in random games are choppy (pure, kane and lynch). All games play fine on my sammy ms 28 and hitachi v59
Backups made from mis verbs, xbc and img burn. I think its the hardware itself, benq must just be shit drives as far as reading backups. Oh well i guess ill get my hands on a liteon and spoof it as others say liteons are great
Alternatively, you could pick up a 120GB WD notebook drive for $55, flash it, and then use it with your 360. That would give you enough room to run 15+ games from your hdd, thus bypassing the BenQ.
