Oh well, here is some info I dug up from the last time I asked this question a year or so ago on AVS:
Here are some widescreen games
half life 2
Doom3
Toca Race Driver 2
Halo PC and Farcry
These games I have been told support widescreen & split screen
Colin McRae Rally 2004
Serious Sam 2
WoO { World of outlaws }
Saturday night speedway ,both by ratbag , support split screen , another racing game also that does is MotoGP2 and also superbike 2001 by EAsports , all support custom resolutions
Anything change? Any other cool widescreen games out there? Particularly multiplayer split-screen games?
thanx
