Since Crysis 2 so far has been a complete disappointment, I've been replaying Crysis 1 and Warhead.

The 64bit version of Crysis 1 is really unstable for me. A lot of crashes, refusals to launch etc. The game is fully patched. Has anyone else been experiencing this? How do you fix it?

The 32bit .exe is absolutely fine.

Dude, can you read name of sub-forum? Its caled Crysis 2 PC discussion.
There is Crysis 1 discussion in another sub-forum. I suggest you to kill this thread and start it again in right place.

You really really needed to post that here? Go to Crysis 1 forums. Dude Crysis 1 is known to have crashes. Your system can't run it That's the point of crysis 1

Let me guess: you have Windows 7? There seem to be lots of problems with that.

Noob question: Can someone really explains to me what a 64bit program does what a 32 Bit can't?

I mean all games most are 32 bit ( i think) and all of them run fine:)

Basically a 32 bit excecutable wil give you less acess to RAM than a 64 bit one will. Crysis 2 probably won't benefit since it was designed with consoles in mind i the first pace and as such will never break any technical barriers.

32 bit only lets you access up to 4G of ram. 64 bit also lets you use more complex assembler commands and more of them per tick. But, in my experience, I see little real world difference ( if any ) between the two, except for more memory available.

Just stick with the 32 bit. 64 bit exe's have had problems ever since they came out. They seem to have never quite got it right. Probably bad asm functions that never worked like they should.
