DCS in VR causing my PC's to lock up ever since 2.9.3.51704

[skybaby68]

I have 3 home PC's, 2 running DCS in VR and 1 running in 2D

PC 1 & 2 are indentical: 19 14900K with 4090, 64GB DDR5 RAM, but PC 1 is running Pimax Crystal & PC 2 is running Quest 3

Both are running OpenXR and since 2.9.3.51704, both of the above PC's will, at around 60% of the time, cause the entire PC to run at a snails pace when DCS finally gets to the main menu. I have the OpenXR FPS counter running and it plummets from the usual 91.0 down to 2, sometimes rising to 30 or so then back to 1-2.

Most of the time it takes the PC with it, having to exit DCS via task manager  & hope the PC gains enough momentary speed to be able to exit DCS and try again.

Invariably it will also do it coming out of a mission, back to the main menu.

 

My 3rd PC running DCS in 2D is an i7 11700K with a 3080Ti & 64GB DDR 4 and is unaffected.

It's worth noting that this is an all new problem since the last update. All PC's were running fine beforehand.

 

If anyone can relate to these problems and can guide me out of this hole I'd be most grateful.

Maybe check this regarding core unparking:

And also sometimes when I get some significant stutters, disabling core No.8 under the core affinity settings has helped. I think that gets mentioned in the linked thread.

my specs: 13700K / 4090 / 64GB RAM / QuestPro

And yes…I had the same problem until recently.

 

Might be 13th/14th gen intel related…

For core parking I use this QuickCPU

Since 2.9.3, I also had crashes and occasional stutters lasting about a minute.

Crashes were resolved by a BIOS update (MSI MPG Carbon).  Memory management was not optimal and DCS is quite demanding from your memory controler specifically if you use the four memory slots (4 x stick of RAM).

Stutters were resolved by using process lasso, removing use of e-cores for DCS, pi_server, and setting high priority for those two.  The sim has never been so smooth and stable.
