Hi Guys! I'm running the same setupt for 2 years now and I never had any issues concerning VST Performance. 2 days ago I moved and then I re-installed my setup in my new home and problems appeared.. I open 1 instance of Superior Drummer with a guitar track with a light-consuming compressers from URS and my audio crackles in playback. I can see my VST Performance going up and down even without any playback going on. Something weird seems to happen with my VST Performance and I really don't like it. I have a Dual Core2 with 4gigs of ram. I never had any problems of that kind even with several instance of cpu consuming vsti such as Amplitube... Please help me on this one! Thanks!
