just bought and tried it, here my first impressions:
The mirrors give very poor image quality (like 2-3 fps) and there are 40 mirrors according to mirrors config app.
Turn off real mirrors and the image is ok, but then you don't see the rear wing (and i like to see if DRS is on or not, so real mirrors is almost a must for me - there also does not seem to be an indicator on the wheel that DRS is on).
Performance seems ok (in vr i get steady fps and no spikes in frametime).
Also seems to handle quite well, spins out when it needs to and has no ABS and TC available at all.
(I know it's not on a real F1 car since 2008 and i mean this as a good thing, because in the F1 '22 game they decided to allow TC to be turned on anyways

)
I hope they fix the mirrors soon. (or is this a bug in CSP, and of no fault of RSS?)
EDIT: another big disappointment on this RSS one is the rpm LEDs are hardly visible (without PP !) ,
something i have no issue with on the ACFL F1 '22 car (which is till now my favorite '22 f1).
