The i9-12900K uses Efficiency Cores (E-Cores). Many DCS players have had issues with this. I would also take a look at the YT video linked below. This helped resolve some problems with the CH-47F in VR for me. Essentially, it's about disabling the E-cores when using DCS only. The E-cores are still available for other apps running in the background. 

Spud Spike - Process Lasso

Never trust a YouTuber that has no idea about PCs. Do not disable E cores and don't use lasso. DCS uses E cores for less important tasks. If you disable them, DCS uses more valuable cores for the same tasks. That's a downside.

True! And "some" have a way of picking up tricks and present them as their own when they haven't the slightest clue of what's going on.

Not disagreeing with your stance on the E-cores. In my use case, the CH-47F is unplayable in VR unless I disable the E-cores. The other modules I own do not seem to have this issue. I tested the A10-A, C, CII, Huey, Apache, and Chinook modules with various maps over the weekend. Only the Chinook seems to exhibit the problem for me. And, it doesn't seem to be related to the map either. To be fair to Spud Spike, we are both using the same 14th Gen i9 CPU. Perhaps this specific CPU is key to the issue. The issue only happens in VR for me. Not certain about the 'YouTuber'. Maybe he is full of crap, but his suggestion is the only thing that makes it playable for me.

S!

I got the game running smooth again, knocking wood! What I did was to disable Core Performance Boost on my motherboard and let motherboard adjust voltages/current. It could be one of those settings or both that cured the insane simulation thread spikes. I presume it is the CPB setting as 7800X3D possibly has no benefit of it. Still testing more, but so far looks good. The insane "hacksaw effect" when using in game VSync and flying low was cured by enabling Anti Lag feature in AMD GPU drivers. Testing some more, but so far so good...

Checking out the Mods now. Had not problem until now.

I have a 14900 also here. Can you get me your dcs.log please?

After more experimentation, I have ruled out the E-cores as the primary issue. I am now getting consistent fps in VR with the E-cores enabled. I'm not sure what actually solved the problem. Some of the things I changed:

• Uninstalled Process Lasso (used to disable the E-cores)
• Uninstalled ReShade 
• Running DCS in Administrator mode.
• Bypassing the DCS folder in Defender.
• Recently, there were updates to both SteamVR and the PSVR2 apps. Maybe that addressed something I was encountering before.
• I also made various tweaks to the DCS settings, like capping the FPS at 90. 

The combination of all of that seems to have really improved the performance. I'm now getting fairly consistent 45 fps in VR with all modules, with occasional brief dips down to 30fps. I'm not seeing the 3-5 fps I was seeing before in the CH-47F.

This you should change. DCS does not like this.
