I just finished downloading Metro 2033 from Steam for the unbelievable price of £29.99 only to find that Metro 2033 won't seem to run in DX11 mode above the resolution of 1280 x 720, If I select DX9 I can then choose any resolution I want.
I've tried editing the user cfg file so that it forces the game to run in 1920 x 1080, However this doesn't do anything at all. :/
I've had the same problem with S.T.A.L.K.E.R CoP and 3DMark Vantage.
I have a horrible feeling it has something to do with me using a TV as a monitor, the TV's native resolution is something like 13xx X 7xx I think, but it can go up to 1920 x 1080.
Core i7 920 system
CF HD5850's
Toshiba REGZA 32" HDTV
Any ideas people?
