maybe this has already been brought up and maybe it should just go into the gaming section, but i'm still a n00b at this forum lol, i just got a 64bit 3400 at 2.2ghz with 1gig ddr ram, and a 5950 ultra 256mb and i was hearing some things about 64 bits not running games right, is this true?, is the 64bit backwards compatible to 32 bit?, i mostly play black hawk down, team sabre, and the join ops beta, but i will be getting far cry, doom3, and half life 2, any body have any experience with the 64 bit gaming? any help would be appreciated

P.S also getting ut2004 and bfvietnam

I think what you had heard is that the 64 bit Windows XP beta does not run some games correctly.

I haven't heard of any compatability problems with the AMD A64 processers and games (probably since the processors have 32 bit instruction paths as well).

ok thnx for the help :D

Most gaming issues should be resolved by the time the full 64-bit version of Windows XP is released. it also will be backwards compatible with existing 32-bit games...at least those running on an Athlon 64.

Yeah XP 64bit is a abit flaky but that will be sorted.

heh I am waiting a lot like you m8... for the right drivers and the like to drop :cool:

but 32bit has not been found wanting so all's well... :D

Mabe it will be in the form of a compatabilitty mode (like xp).
Definitely worth keeping an eye on.

The Athlon64 does all the compatability it will detect what the application is and use the mode needed.

Are you saying that it will be irrelevent as to whether the upcomming 64bit windows support's 32bit programs or not, that the A64 will do it for windows.
Because that's what I was referring to. Window's 64bit backwards compatability. :)

Windows 64bit has to support both 64 bit and 32bit applications but it doesn't use a compatablity mode. Windows will run the application and send information to the Athlon 64 witch will then use whatever coding is needed. But will always use 64bit (on a 64bit OS) but for older games it will also use 32bit at the same time as it's a seperate regisiter.

That's what I thought you meant.
Yea, I just didn't know how windows would implement 32bit backwards compatibility. I wonder if it will have a form of compatibility mode for win95 apps (like xp), or if they will just wash their hands of anything that old (Like I have). :)

It doesnt matter what matter is performance. Now its around 20% performance hit and they say when 64bit drivers and XP64 is done the hit will be much smaller (3%?)

When new games is made for 64bit (e.g. UT 2004) we can see performance boost 5-20%.

Try it out and download XP64 bit and make sure your hardware and game developers get to know you want 64bit, i would appreciate it, im saving up for a socket 939 motherboard and CPU!

Lots of fun, i wonder if they could release 64bit version of Deus Ex 2. Maybe if we nag them alot http://jooh.no/root/pix/smilies/tril_lol.gif

Could 64-bit support for current games be released by way of a patch or something? Or would the entire engine have to be re-written to support it?

Most likely there'd have to be a complete reinstall of the game to go from 32 bits to 64 bits, but as far as rewriting the engine, that probably wouldn't be necessary. A lot depends on the compiler that they used, but I'd be willing to bet that it would be as simple as recompiling with a 64bit version of the compiler. (This would produce the right output, but would mean that all the executable parts would have to be replaced on the machines running it).

On the other hand, I'd bet that most games are somewhat well optimized for 32 bit native environments right now, and while it should be possible to simply recompile for 64bit environments, it wouldn't run much better than the 32bit version, if at all. The better tactic would be to spend a bit of time reoptimizing the source code for the new environment first, then do the recompile. That would allow for more efficiency, and most likely better performance than a simple 32-64 compiling alone.

(Speaking from experience gained several years ago writing first 16bit Windows 3.1 applications and then porting some of those over to the 32bit Windows95 environment)

From what i have heard UT2003 can run in 64bit with just a patch. Plus they said it took only a couple of weeks to do :)
