RTXA4000 550 Laggy and black screen reboot / crash

6.8.0-52-generic Ubuntu
RTXA4000 driver version 550.120

I had loads of issues with installing nvidia drivers causing black screen boot loops. After finally getting it running the cursor is lagging and UI is struggling. The machine also sometime just goes to a black screen and reboots.

I have had this driver and OS running fine on other systems and I have had this system running fine with earlier OS driver systems. Any help in fixing would be super helpful:
