Currently UEFI does not have HPET off option.
I did do some 3DM13 TS runs yesterday
. No BCLK meddling, just runs to know how to make OS tweaked for "optimal" performance plus know if resuming from "Sleep" I'm losing any performance, etc.
Comparing results 2 & 3 FreeSync being on or not was not swaying results, in 3DM FS under W10 FreeSync being On knocks result down by ~1000 points for me, results in OP of thread in my sig. Then also result 2 is with HPET on and 3 off, no difference other than run to run variance. Result 4 was to see run to run variance, IIRC done after run 3.
Comparing results 1 & 2 resuming system from "Sleep" with HPET On no difference vs reboot run. Will try a run from "Sleep" with HPET Off.
Today I did some CB R15 (OP of my thread has some W7).From Resume, HPET On. (Click to show)
From boot, HPET On. (Click to show)
From boot, HPET Off. (Click to show)
From Resume, HPET Off. (Click to show)
All results are with Performance Bias [Auto] in UEFI. The 1703 result in CB R15 is from W7, same OC profile, High Performance power plan, with min CPU State 5% for down clock/volting, Core Parking disabled (100%). As this gave best results for me.
As you can see from screenies I'm on W10 Balanced with CP 50%, this is not only "Optimal" for 3DM FS but also CB R15, also matching W7 result within run to run variance.
So far W10 is giving me like performance as W7, I had concerns of going to W10 due to stuff on web that W7 scheduler was better for Ryzen. For me Ryzen power plan has been pants so far as well, my modded Balanced PP is better IMO. Also rolling with HPET On.
My W10C was clean install from ISO, few pages back I highlighted to bluej511 HPET was On for me, link
