I looked at the issues in this post, and well. On my 13900kf, with 64gb xpg 6000mhz, and MsI gaming x trio 4090 and 2 2tb high speed nvmes… so basically another high end rig.
In the last month or so it’s gotten bad, then out of curiosity I took out my laptop and well… it blew my rig out of the water, though I had no discernible hardware issues.
Anyway, I spent the 3 day weekend troubleshooting my rig, playing with all settings, on my bios, windows, all nvidia settings, all FS settings, dumped some AI load too… and well… I was able to claw back FPS from low 30s up to mid 40s, which shows a much better improvement with frame gen, obv.
Though I know I still didn’t solve the problem, I had a running CPU utilization in taskman of 5% flying a PMDG737 over Manhattan, and seriously my rig was running cool and quiet except for the 4090.
Anyway… reinstalling Windows now.
You are all relative heroes if this works.
