Fps :(

[lil_striker90]

Basically heres the problem,

i got nod32 anti virus, i got an x850 pro vivo agp 256mb, i play counter strike source de_dust2 fps over 90 usually, i get onto nuke i get 50fps, for some reason 2day i played and i was getting like 25-35, on high graphics, highest resolution 2xaa, etc.. my fps on de_dust2 is now down to 50-60 now, and i cant find the reason why in the fall of my fps and i find it laggy as hell, could it be my a/v ? i tryed o/c my gpu, but no difference in fps, o/c cpu fps stayed the same, put the game on lowest graphics and same fps, i have no idea why and cant seem to find a reasonable answer, any help would be appreciated

peace out

Very much doubt it's the AV

Try uninstalling, driver cleaning and re-installing the new drivers?
