Thank you for your detailed follow-up and for the extensive troubleshooting you've already performed. I can see you've invested considerable time and effort into identifying the root cause, and I genuinely appreciate the clarity you've provided. All of this suggests we are likely dealing with a compatibility or optimization issue specific to this title or game mode when running on your current GPU and driver stack, rather than a hardware stability problem.
At this point, I will need to do further research on this matter and post the response on this thread once available.
@megaro7 , I empathize with your situation and the issue you are facing. However, I kindly request that you create a new thread for your case. This will allow us to focus on your specific problem and provide you with better assistance.
