The system, Aorus Master Z690, 32GB DDR5, Firecuda 2Tb M2, 12900K, 3080Ti EVGA FTW3, Reverb G2.
I Only fly in VR, and all my settings are dialed specifically for MSFS2020 in VR.
For non-VR, I could push things a bit further.
So here it is.
Overclocking the 12900K has been a painful experience, one I won’t recommend. But after countless crashes to BIOS, I’ve managed to get a stable 53x all P Cores, 41x all E Cores, and Cache Ratio at 45x. Voltage is Fixed at 1.350 v, offset -0.020 v.
I also had to get a new AIO, Arctic Freezer 420 aRGB or something like that. Which drop temperatures quite a bit.
The crazy road is to test with Cinebench if you ‘only’ or ‘mainly’ are using your system for gaming and or the sim.
So I gave up on Cinebench and did the tests running the sim, it can run forever now. Temperatures mid 50’s for the most part.
Now, about the 3080Ti, I’ve been very happy but couldn’t get rid of stutters, but I’ve got it now!
First of all, and I know this is silly, close or minimize any window and have only the sim running on the screen, yep, that crazily works for me.
And two, undervolt your GPU to a stable frequency, rather than having the thing trying to get settled, which it never does and causes stutters again.
Mine is clocked with Curve at 1995 and 950v. Memory at +800, Power Limit at 110, Temperature Limit at max. Custom fan curve at 100% when it hits 60, my personal preference. Now it won’t pass 79 degrees even flying in NYC, real crazy weather, everything Ultra. LOD 200 which is CPU bound and that’s the sweet spot for my CPU and 30 to 45 fps in VR.
Last, for VR users like me, install and configure OpenXR Toolkit to your taste, this tool changes everything.
There you have it, hopefully, some of you will find this info useful.
p.s. Debloat Windows!
