Today I receive my Crystal, and my first impressions are very good.
The visuals are amazing, the upgrade from a Pico 4 (VD Godlike with H264+@400) is very very noticeable. Now in the MSFS 2020 I can read everything in the cockpit, and also I can appreciate more details in the horizon (unfortunately, I could only achieve 32fps with my current settings 
).
In the Assetto Corsa is the same, now everything is very sharp, but this time at 90fps .
The bad thing is the controller tracking, with the current FW (non the beta one), when I tried to used it to aim in Sierra Squad or Contractors, sometimes the left hand gets crazy (drift) until I release the grap button. This is more common if I have the fpsVR overlay in the left hand enabled. Also it suffers from jitter time to time.
On the other side, the headset tracking is very good. Until now I haden’t any issue with it.
There is a chance to get in the beta @PimaxQuorra? Because with this control tracking, is impossible to play shooters (or any other game that requires precision).
