I ran prime small pft for an hour and a half with no errors and then ran a blend for six hours with no errors. I was playing bioshock and noticed occasional stuttering during heavy action. I also see alot of texture popup in crysis and flight simulator x. Could this have been a disk fragmentation issue? What would cause the texture popup issues or is that just normal in those games? I have seen both issues at any settings I have had in the process of tweeking my pc. Any utilities or recomendation would be greatly appriciated.
