This can be due to dcs’ poor cpu core management and allocation. Try Process lasso and for dcs.exe set core affinity to only the p-cores (exclude e-cores).
U have time still. We don't even know yet if vendors will have an alternative or if WMR will still work if installed separately etc... I would not rush unless you were just looking for an excuse to upgrade
I have experimented with process lasso and found something that seems to work. Went to I/O priorities and matched DCS with low priority. Seems to force DCS to not assign I/O E-cores. Relaunched DCS after a reboot a couple times and I have not experienced the spikes and the log show no I/O cores assigned. Not sure if this is affecting anything else though as I do not really know what I'm doing here Anyway, worth a try!

You will be CPU limited with your 4090, not GPU. MSAAx2 or x4 or DLAA is your own preference ... different people different choices. Most of the rest you should be able to max out but often grass is dialed down, civ traffic but not required.
I have the same system as you @cow_art and exactly the same issue and same fix (I toggle visib range on my side ).
Only difference is I use DCS Standalone, not Steam.
Err no. both of us have it switched off in VB and we do not get this popup
Have you looked into the steamvr settings? BTW... u are using DCS standalone I assume?
