Just played through the part where you're buddies jet crashes and you run to pick up the flight recorder off the seat. It's raining and lots of shooting so figured that'd be a good test run. lowest was 17.5 and highest was 26.3.
DX10 vista giving like a 30-40% performance hit over xp? :/
edit* just read thought TweakGuides.com - Crysis Warhead Tweak Guide
checkin out all the stuff, and apparently yeah, the performance drop in DX10 is even more pronounced than in the original crysis.
has some cool comparrison images and the usual info on how to tweak DX9 to pseudo-enthusiast settings for a performance boost.
I'll deal with the hit. :/ if it gets on my nerves that much, or if its more pronounced in FC2... I'll just get a 4870 and crossfirex :/
