so i tried the 64bit exe today and while it runs great FPS-wise, I noticed a couple bugs.
First is when i tried to use the purchase terminal, had about a 10-15 second freeze when I switched to the engineer from the soldier.
Second is when the game ended. when the map select timer ended, I lost all sound channels except for the front and rear speakers (continued on the next map as well) and thought i blew my subwoofer as there was no bass at all, including my music program. Once I quit the game my sound returned to normal. haven't tried it again as i don't want to damage anything, currently have the Creative Audigy 5/Rx sound card with Daniel K drivers. haven't experienced this in 32bit at all.
I would like to test some more but the sound bug has me paranoid, I don't want to damage my sound card and speakers
