Hi, I changed my CPU over 3 months ago, much faster system, took the time to reinstall and configure everything. However the new system which is a much faster system can't manage some games. The only difference is it windows 7 not Xp, as that was what was installed when I got it. There are no other programs running on startup just gamex, I've even created a batch.exe file that launches mame with high priority, which helped, but some games just won't run at full speed. For example mk1 and mk2 fine mk3 and above stutter, tekken 1 can be hit and miss. Any tips? I don't want to have to uninstall everything and go back to Xp and configure again.
