"Hey guys, I'm experiencing some insane GPU scaling issues with Unreal Engine 5 on my rig and I'm hoping someone can help me troubleshoot. I've got an AMD RX 6800 XT and an Intel Core i9, but no matter what settings I tweak, I'm still getting this ridiculous lag spike every time I load a new scene. Anyone else having issues like this or know what I can try?"

"Hey guys, had a similar issue with UE5 on my 3080. Try checking your power management settings and also see if your GPU is being limited by your power supply. Also, what's your engine settings and scene complexity looking like?"

"Lol, been there, done that. Have you tried disabling some of the advanced features in the GPU settings like ray tracing or global illumination? It might help reduce the lag, at least till you figure out the root cause."
