My first unit that I received I had similar issues. Had mad max and cyberpunk crash on me at various times. And also had issues when waking the deck up (slow and unresponsive)
I RMA’d my unit and recieved a replacement and it’s been much much better. No issues whatsoever.
If your in any doubt that your item might be faulty, just send it back for peace of mind.
Hope you get sorted
