Nope, its not antivirus, not SLI (its off), not power settings or anything else on your list. I notice Frey avoids the city. Mine stutters over London big time even with decent frame rates. There must be a setting that causes the stuttering over London. I don't have textures original either. 2560 x 1600 is a must because the sim shimmers horribly because of the lack of AA and AF on my 30" monitor, even then the lack of AA/AF shows.
