all other times I have a very solid 50-60FPS on "high" (v-sync on), rig is as follows;
i7 930 @ 3.9ghz (HT on)
12GB DDR3 @ 1630ish mhz
MSI Twin Frozr GTX 660, overclocked about 50mhz on the core and 30mhz on the memory
anyone else having this same issue?
----update
after reading another thread and trying these settings as given by someone:
Anitliasing = FXAA
V-Sync = NO
Advance Graphics = High
Motion Blur = Low
Lens Flare = Yes
---
i no longer have the problem and am usually getting 50-80fps constant... wonder which settings are causing that problem
