Regarding performance:
Your specs are very close to mine: R7 3700X / 16GB RAM / 1000GB SSD / RTX3060TI + Reverb G2
I think you can expect an acceptable performance on your system. The most important settings are the two render scales in Open XR and inside the sim. I am running both at 80% and getting 30+ fps on high settings. Very satisfied with the performance and having a great time flying in the sim. If you need more frames you can lower the Open XR render scale down to 50% and maybe enable motion reprojection.
