FPS all over the place

[DaveP63]

Installed on my new rig and the FPS are all over the place. 300 to 6 to 90 to 165 to 2 to 340, etc. 

 

Specs: I7-14700KF, 32 mb RAM, 2TB nvme SSD, RTX4070 super, 165 Hz monitor (flatscreen, no VR)

 

First quick mission over the channel.

Any assistance appreciated

Update, changing the ingame refresh rate to 120 seems to have fixed it. I hope.
