GTX 480 Graphics card and FEAR Extraction point help

hello,

i have a 1080p aleinware optx 2310 monitor, a gtx 480 graphics card, i5 processor, 8 gigs ram, windows 7 home premium 64 bit. i can safely assume i can max FEAR out. when i played FEAR the highest resolution option was 1920 X 1080 X 32 and it said the game was not optimized for that resolution, but i figure the highest resolution is the best right?

in fear extraction point the highest resolution is 1600 X 1200 X 32 when i set to that it makes things look a little bigger than they did with FEAR. should i actually be setting my computer (nvidia control panel or display settings) to 1600 X 1200 X 32? if not then what is the best graphics setting for my monitor.

thanks for any help

If your monitor is 1080p, then the highest resolution you can get is 1920x1080. Your monitor shouldn't be able to display 1600x1200, unless it is downscaling it for you.
