GTX280, C2D, E8600, 4GB, XP
Per your instructions, this is what I got:
- 82 was the lowest FPS with stat fps command hopping around central area and up around edge of this area; I think it averaged around 95 or more.
- 105 looking toward fighting warrior statues at other side of map from main blgd. area
- 92 looking from warrior statues back half-way between bldgs and mountain.
I set it on 5 bots (which would actually be 6 total combatants), but it doesn't make much difference either way. not sure what your OS is but I would expect Vista or 7 to be slightly less.
