Please log in for more thread options thanks for the thoughts,
firstly the SATA is rated at 3Gb/s so hopefully this aint the problem. good
point though~!
Vista gave the 8500Gt a rating of 5ish (still didnt fix stutter) if memory
serves me, where my onboard is 3.2 so graphics could be better in general but
should be ok.
Stutter is definitely worse when panning and ticker tape...why does the
ticker tape come good and then stutter again, where are the bottlenecks?
if the on board graphics is up to the job what else is there?
