Unexpected major decrease in frame rate on GTX 1650
Unexpected major decrease in frame rate on GTX 1650
I was using Acer Nitro 5 an515-57 with 8 GB RAM and Core I5-11400H GTX 1650 Insyde Corp. V1.17 on Windows 10 Pro x64. Two days ago while playing Mafia III, my GPU fan spiked to 6666 RPM and performance dropped from 60 fps to 7-11. After that, game textures also rerendered. Earlier, during CS2 playthroughs, FPS didn’t drop despite similar issues. I suspected a driver problem, tried updating and reinstalling Windows, but the issue persisted. In Device Manager, the GPU listed as deleted or non-startable. After a fresh install, it still reported: “Device needs to be installed.” No further details on required updates.
It's even more odd that reinstalling the same drivers again fixed everything, but then it dropped back to 7 fps after rebooting the PC.
It started to function occasionally, checking performance each time. The first version ran at 49 frames per second, the second after a restart hit 7, and the third after another reboot reached 49. It seems this is still occurring.
