Hello guys, I am running Parallels 10 on Mac OS X 10.10 (Yosemite) DP6. All my VMs are running slow (stuttering). I have tried lots of different options: turning off/DX9/DX10 3D acceleration, uninstalling/reinstalling Parallels tools, turning on/off Adaptive Hypervisor, Coherence on/off, disabling sound, internal/external drive for VM, Windows 7, Windows 8.1, Windows Server 2012... I have Googled the issue, and searched the Parallels KB, and can't find anything. All slow and stuttering. Nothing in the Windows Event Log, or the Mac OS X Console. Any ideas? I know Mac OS X 10.10 is beta, and I am prepared for it to be broken. I just wanted to know if it was a known issue, if there was a workaround, or if people knew of a fix? Thanks a lot, Mark.
