My Manli Nebula RTX 5060 8GB keeps hitting driver timeouts and crashing during high-action scenes in Returnal. Can I fix this with process priority?

This card is a real 'piece of work.' Every time I'm about to nail a boss, it decides to crash to desktop or just reboot the whole PC—absolutely ridiculous. The Manli Nebula RTX 5060 8GB keeps triggering TDR timeouts when handling complex lighting effects. I tried lowering all the graphics settings, but for some reason, that actually made it crash more often, which is just laughable. I ended up using the registry editor to disable Windows MPO (Multi-Plane Overlay) and slightly underclocked the memory frequency by 50MHz. Checking HWInfo, the memory temp dropped from 84℃ to a more reasonable 72 - 78℃, and the crashes completely vanished. I did notice my browser flickering a bit after disabling MPO, but a quick update to the browser's hardware acceleration driver fixed that. Core clocks are now steady at 2300 - 2400MHz with power draw between 110 - 130W. I exported all the crash logs via the system error tool to make sure it's clean, and fans are holding steady at 1400 - 1600 RPM.
