First off my system specs AMD X2 6000 (3ghz) Geforce 8800GTX (768mb) 4096 MB RAM RAID 0 harddrive configuration Windows Vista 64 Ultimate Latest video card drivers from nvidia SB 2.460 I am experiencing extreme FPS slowdowns and stuttering when i unbutton my TC, the worst when i unbutton fully (standing up) I have no other problems with low fps in SB, when in external view or when the tc is buttoned i have very good FPS, mostly around 62.50 droping to 50, i have tried fiddling with the terrain sliders to no help, but as soon as i unbutton my TC the FPS crashdives to between 11 and 7, i can be looking at exactly the same scenery in external with no problems whatsoever but as soon i go to TC view it drops. Another thing that comes with it is a bad case of stuttering and im not talking about the slowdown caused by the FPS drop, it's the kind that freezes the whole image for a milisecond or two every couple of seconds, hard to explain but hopefully you'll understand what i mean. I'm gonna do more investigative work when i get home today, if anybody knows anything about this issue let me know. Ssnake let me know if theres anything i can do to make things easier for you, any logs from dxdiag or something similar.
