Performance Issue Returned – Unplayable Second Half (PC)

It has been 1–2 months since I first reported this issue and now it is happening again. I managed to play “okay” for a while by limiting FPS to 60 and the refresh rate, but now the same problem is back even with those settings. In the second half the GPU usage jumps to 99%, FPS drops from 60 to 20–30, and there is huge input lag, and it sometimes stays like this even in the menus. I just want to play normally. Has anyone finally found a real fix or workaround for this? My specs: i5-12500H, 16GB RAM, RTX 3050 Laptop 4GB, Windows 11.
