Hi all,
I had put this game away with the flickering issue.Got a q9650 and ati 4870x2 and by chance happened upon this post and whoopee got crossfire to work for me.Renamed to crysis.exe and flickering stops in intro after about 5 seconds...confirmed crossfire is working with ati tray tools on screen display.Both gpu are at 99.99% workload,second gpu temps a bit lower and high fps also...maybe i will play the new expansion packs:)
Thanks to all concerned:)
ps...using win xp..cat 10.12
