HP Reverb G2 causing frame drops and force feedback cutouts in iRacing

[mgm41887]

I play iRacing (and Assetto Corsa but the problem described below is not as severe in that game). I have a Simucube 2 Pro/Ascher F28 combo. The last two days the FFB has been cutting out at the same time that I get frame drops while racing. The HP Reverb G2 is from November of 2021. The Simucube and the Ascher are from February of this year.

I've tested it in AC and iRacing and its worse in iRacing (VR screens fully freeze for a noticeable period of time and FFB cuts out entirely) than AC (just frame drops but very brief, no loss of FFB). In AC the hardware monitoring app shows spikes in CPU and GPU latency when the frames drop. In iRacing I do not see spikes on the meter blackbox when the frames drop and the FFB cuts out.

I finally tried driving on my monitor (VR off) and the problem did not recur, leading me to believe that the VR headset is the issue. I thought I had the problem solved by putting the DisplayPort cable into a different port on my GPU but it worked for only a day. 

I have been having VR issues with iRacing for a while. Sometimes when I load into a track it will blue screen and crash back to the WMR home screen. Other times it will blue screen briefly and then when it re-appears the image will start rotating left or right. Sometimes that problem resolves on its own and sometimes it blue screens again and crashes back to the WMR home screen.

Is this a problem caused by a faulty cable? Is this a driver issue?

This may be anecdotal but it seems to be worse when the room I am playing in is warm. Could it be an overheating issue? Its not an overheating issue on my PC. Ryzen master said my CPU was at 62 degrees when I just stopped playing. I dont think its a power issue because I've had the same setup for two-ish years and it just started causing problems the last few days. Or maybe my PSU is dying? It's a Corsair 750W

My PC specs are:

AMD 5600X
Nvidia 3080FE
32 GB 3600mhz RAM
Simucube 2 Pro
Ascher F28

Any suggestions?
