Steam and Crysis 64-bit

Hudzy · 24 Sep 2008 at 16:41

Just a warning to anybody who expects to get the whole game when they buy something on Steam, you won't get the 64-bit version of Crysis.

I'm a bit annoyed now after seeing benchmarks showing much better fps in the 64-bit version. It's a bit poor really for the absence of it to not be mentioned on Steam.

It really works better in 64 bit?

According to this:

I haven't tested it myself, though I'd like to.

i noticed about 1FPS difference in the 64bit version of crysis. I call shenanigans on that article.

Surely if you have 4Gb of ram then the 64-bit version will have access to all of it

I heard that Crytek released it without 64bit version - it will come in a patch soon =\

That's an OS specific issue. If your OS can detect all the ram, then existing x86 applications can use it as well. And there's zero difference between x86 and x64 bit versions of Crysis.

that's warhead, he's talking about the original crysis

would it work if someone sent you the bin files required for the 64bit version

Really? I was under the impression that 32-bit apps on a 64-bit OS were still contrained by 32-bit hardware limits.

no you don't, because he's wrong.

32-bit programs can only access a maximum of 2GB of memory, just as they could in a 32-bit OS. you need a 64-bit exceutable to access more than this 2GB addressing limit.

you're right - a 32 bit app on a 64 bit OS can still only allocate 2GB ram.

I'm not sure to be honest. I imagine it might.

Even if the performance difference isn't that much, I still think they should mention you don't get the 64 bit version.

iviv learns an important lesson.. not everything you read on the internet is true

Very interesting. I did not know this. Looking foward to patch

Crysis 32 bit comes 'Large Address Aware' enabled

Therefore if you run 32 bit crysis on a 64 bit PC, it would automatically have 4GB available to the process.

I'm sure Crysis doesn't use over 2gb anyway - however the point still remains that 32 bit apps on a 64 bit os can use 4gb is 'LAA" enabled.

Personally I get an extra 5FPS ish running in 64-bit with 2GB ram. Online is a lot better too, but of course it means you can't use punkbuster.
