Kevin, I'm using a NVIDIA GeForce GT 750M with 2 GB of ram. I have 16 GB of ram on my machine. I do use nests and masking. All work fine when not using CUDA. No devices connected and no external monitor. The first time the whole computer had a Kernel Panic. The next time, just Premiere. Then Kernel panic. Then I switched back to Open CL. Yes, the fans are blowing non-stop. This also happens when not using CUDA. Only CUDA makes my crash and kernel panic. When using Open CL, I can have nests in nests with masks on each instance with no problem at full resolution Projects are not very effect heavy. I usually use the 3 way color corrector. Sometimes I use Red Giant Universe plug ins and luma key Can you confirm that 10.10 is running without incidents? I'd rather wait if not, just to be on the safe side
