Best windows for Arma 2: XP / Vista / Seven ?

[vento]

I'm currently running Arma II on this sweet rig:

I7@3.2Ghz
GTX 295
6Gb ram
Vista 64

I did all the -winxp/no blur/crysis.exe tricks and gain a lot of fps, but still some players reports better perf on older system.

From what I heard, XP makes Arma 2 runs much better than Vista, so I got a few questions:

- can I have a solid confirmation that XP > Vista ?
- If yes is there any chance for perf under Vista to be improved by a future patch ?
- How about Seven ? I could consider upgrading, but I really don't want to go back to XP.
- Finally: 32/64 bits, wich is the best ? I know Arma 2 doesn't exploite 64 bits system, but it would be a shame if it ran slower on them.

Thanks for your answer and all apologies if this subject has already been discussed in a particular topic.

People who seems to complain more are Vista users, specially the quad owners. But there is no scientific prove. Maybe there are more Vista users than the others.

I'd so go 7. With a system as new as your own, I don't think you'd see a positive FPS gain from going to XP.

Go Seven. For the same reason Binary said. I did that, and my FPS improved from Windows XP.

Thanks for your answers guys, I'll go for seven and give my feedback.

Oh I must add, I have 64-bit, because of all of my RAM. If you have large quantities of RAM (4GB and above) go 64bit.

Windows 7 works great for me too.

I recently tried RC 7201 64bit and latest drivers on GTX295, now I get micro (hell i;ll call it macro!) stutter.

SLi wouldnt work for me under vista, seems to under 7 however the stutter is worse then running on single GPU mode. I may be a lone one here, but been having massive probs getting my GTX295 to behave with every driver going back to 181's..

PS> I have i7 system as well

EDIT: If you want 6Gb ram, you need 64bit.. 32bit will only use 3gb ram

I know of three people now who have reported a large increase in framerate by reverting from Vista to XP.

From my understanding it seems most games run better with XP than with Vista
