Frezy Posted February 15, 2015 Share Posted February 15, 2015 Hey, I have some Problems with VMware. It is lagging all the time. It Takes 15 minutes to boot Windows 8.1 and it is unpossible to work with. somebody has Problems too? I think it has something to Do with voodosynctsc? Or with the Kernel Patch? My specs: Intel i7-5820k Evga x99 ftw GeForce 660 ti Boot-Args: Kext-dev-Mode=1 npci=0x3000 nvdadrv=1 kexts: Voodotsc Nullcpu Fakesmc Thank you Frezy Link to comment https://www.insanelymac.com/forum/topic/304583-x99-vmware-stuck/ Share on other sites More sharing options...
jamiethemorris Posted February 18, 2015 Share Posted February 18, 2015 Install GenericUSBXHCI. For some reason with X99 the vanilla kext gets tons of interrupts on XHCI which hurts performance quite a bit in general, not just in vmware. GUXHCI Does not have this issue, so that will fix your vmware issues and boost performance in general (at least according to benchmarks - someone mentioned gaining 3500 points in GB after installing the kext). Your other option is to disable USB 3.0 in the BIOS if you don't need it.
