Crysis Warhead launched worldwide today and our colleagues from PCGamesHardware.com certainly didn’t waste time, as they already bought the game and made some DX10 vs. DX9 comparisons at different detail settings.
Difference in clarity and detail is evident, and DX10 really has an upper hand, but note that for that little extra, you’ll have to buy a DX10 card. Enthusiasts probably won’t have a problem with that, as they probably own one or four of these, but you can get a DX10 card fairly cheap nowadays; just scroll through our reviews if you need help.
In case you prefer Steam, their service will unlock the game in “approximately 13 hours” (at press time), so until then, have fun looking at the comparisons here.
UPDATE: Our hat is off to these guys, as mere hours later they also posted a benchmark of the game and some general info about the game and in-game stuff and you can check it out here.
