I setup Windows 7 64bit on one of my Arcade PC's and got everything running, but had an issue with the boot resolution as it output 1024x768 for about half a second even with the low resolution boot screen enabled. So I decided to try XP 64bit instead, but have noticed a couple of games that were running full speed on Windows 7 are really choppy and dropping below 80% on XP 64bit. The games is question are Tekken 3 and NFL Blitz. I used exactly the same 64bit build and set-up of Mame on both operating systems.
So my question is:-
Is there a performance difference between XP 64bit and Windows 7 64bit when using a 64bit build of Mame?
