Since my upgrade to XP x64, I've been looking for patches so that my favourite titles can benefit from the extra-spicy new registers, and other cunning tricks.
So far, I've found I have one game that can actually do x64 - Chronicles of Riddick. Which I'll be reinstalling tonight.
There were rumours of a 64-bit patch for Far Cry, that then turned out to be a complete new version ("with more objects" (!?)), but it seems largely rumour (discussion boards suggest that signing up for the patch at the AMD site leaves you with an "it'll be out soon!" type message).
Doom 3 - no x64 patch.
Other games I own... still nothing.
I know it's early days yet, but c'mon! C'mon! If you're a game developer, please compile an x64 version too!
I am working on a 64 bit version of my network Pong...;)
What about UT2004? I remember the Unreal devs* talking very enthusiastically about 64-bit stuff from early on.
(who are local to me, by the way-- less than 20 miles away. Although I'm seriously considering moving to Australia to hang out with you guys. We'd laugh; we'd cry. It'd be good times.)
Great, if you wouldn't mind hopping off to smack Mr Sweeney for me...
I spent some time running the 32 bit version *cough* testing until 3am *cough* under x64, and it runs really well.
An x64 patch may or may not actually make a huge difference at this point - it runs without issue (that I've seen), unlike some of those other games...
