VR stuttering - less cores, less stuttering (to a point)

[Alexified]

Today is another one of those days where I pull out my Quest 3, start DCS on an i9-13900K and a 4090, and think to myself, "Today, it's just going to run smoothly..." - and I'm disappointed again.
And the same loop over and over again. And I check the VD settings, check my TP-Link Archer BE550 6GHz settings, check the VD settings on the Quest, and the floor stutters like crazy during flight.
I've already noticed that the movements of a wireless mouse can cause performance drops.
In my frustration today, I unplugged the wireless USB transmitter on the Corsair mouse, even turned off my phone next to me to see if that might be the cause... no effect.

The strange thing is, every now and then, out of the blue, I have a latency below 40, buttery smooth turns, everything is fantastic. And then, after a few hills and cities, just when I thought "FINALLY!"... it starts all over again.

Rarely has a piece of software combined with hardware frustrated me so much.

I've tried the smallest settings, the lowest bitrates, the fewest tasks in Windows—just about everything. The same problem remains: the cockpit looks and moves like I'm on the live set of Top Gun, and the entire scenery reminds me of my Amiga 500.

ive got i7 12700kf 64GB ram

RTX4070 12GBvram

VR Quest 2 At 72hz 

Msi z690A

i cant play vr without the ghosting efect because i can not holdd72 fps Why???  text map is on high, i fly the apache

i ve set off core parking in windows ,ohter games are running very fine with no cores are parked , when i play dcs cores are parked, used Process lasso , still can no t hold 72 fps without dlss

What the hell is wrong with dcs I think 72fps should hold . i mean in the counter the yellow and the green line are heavely drawing ( like a kid that draws a drawing)  

Or is just not possible with a rtx4070 to get 72hz in a quest with quest link???

What resolution are you running the headset at and what are your DCS settings?
