the effect of 64 bit vista os on gaming performance

i use a 64bit vista os and i have a doubt whether i will be able to play the older games. somebody please help me

you can still check if they still work, just give them a go. If they don't work try compatability mode before you give up on them.

You will be able to do anything with Vista 64 that you do on 32. Only games that are like 10 years old might not work (I have a game from 1996 that works perfectly)

I use vista 64 bit and all my old games work just fine. I can still play Doom and Magic Carpet too, and those games are WAY OLD. So I have never ran into any problems. For old old games if nothing else then just use DosBox.

The only compatiblity issues you MAY have are for drivers. Almost any software that runs in 32 will work in 64
