Offline with ndisles, default tower, enabled pan [F8]:
Wait 15sec, now pan right:
On first 360 degrees I get stutters as (Cnt=) starts counting and "Used" increases (as shown in above pictures)
I continue the right pan for several revolutions and now its very smooth at 59-60fps, only interrupted by 2 or 3 very small (almost unnoticeable) stutters on every revolution.
Now disable detailed terrain and restart game:
Again I get stutters on first right pan and "Used" increases.
I can't see any stutters in the following revolutions.
Note #1: in game with absolute minimum settings (vsync=on) and running WinXP with less than 18 processes, I experience occasionally very small stutters, typically (but not always) when changing views.
Note #2: CPU is running with both cores - apparently I'm one of the lucky Athlon X2 users.
