Yes, this laptop is much happier now! I'm surprised as I was using the patch on an AMD build box before it was even committed with only a cgd speed-up to report. The unhappy laptop has a cpu0: "Intel(R) Core(TM) i7-8665U CPU @ 1.90GHz" cpu0: features1 0x7ffafbff<TM2,SSSE3,SDBG,FMA,CX16,xTPR,PDCM,PCID,SSE41,SSE42> cpu0: features1 0x7ffafbff<X2APIC,MOVBE,POPCNT,DEADLINE,AES,XSAVE,OSXSAVE,AVX> Cheers, Patrick
