Higher res, lower settings. Need the extra pixel resolution to see far-off objects, especially when sniping.
Good to know. Any tips on what settings are the biggest resource hogs? With medium settings @1080 FRAPs shows as low as 19FPS. I haven't done too much tweaking yet, just got the game a few hours ago from Amazon (on sale right now).
EDIT: When the NBA game is done I'll go back in and try all low settings and see how it looks.
