This happens every 60 minutes from the time I start an iRacing Session. It never fails me, not once!! races 60 minutes or longer are out of the question. It happens with my Pimax 6K XR and my Oculus Rift S. I’ve sent the MSI machine in twice for warrantee. They replaced the RXT 2070 Video Card twice and the motherboard as well.

This has been haunting me for 16 months now!!! I’m about to sell this machine and start over with someone elses!!
