I can confirm that. I had a Athlon X2 that fried recently due to lightning. I replaced it with a Core 2 Duo and I see a difference in the CPU usage. With the Athlon X2, I would never see the CPU usage go higher than 55%. With the C2D, I get results similar to 2Dogs where I often get higher than 80% usage. But I read that DVDMF patch 2 was taking advantage of AMD X2. Hopefully this will be the same for VS 11 patch that should come any time soon !??I've seen quite a few mentions of Video Studio not being well optimised for AMD dual core cpu's. Whilst I don't know if that's the case, I can say that VS11+ seems to make pretty good use of the 1.8Ghz Core 2 Duo T2400 cpu in my laptop, as the png below shows. It's a Task Manager screenshot made whilst VS11+ was rendering a MiniDV avi file to mpeg-2.
AMD or pentium
