Unless they came out with a patch recently or something I had no idea that farcry supported HDR.
So what im saying is I dont think farcry supports HDR, just crazy bump mapping and stuff. Just because the card supports it doesnt mean the game does, im sorry
. If you really want to test HDR try any Source engine game (counter strike: source, half life 2).
Again I might be wrong, i havent played farcry in a long while.
