I woke up to find that my gaming performance took a nosedive overnight, and I'm trying to figure out why. Typically, I get around 70-90 FPS on games like Helldivers 2 and Oblivion Remastered, but now I'm struggling with less than 40 FPS on Helldivers 2 and under 25 FPS on Oblivion, despite not changing any game settings.
Here's some context:
- My laptop's cooling fans were replaced a while back, so I shouldn't have dust issues. The thermal paste was also reapplied at that time.
- I've noticed a significant temperature difference between my CPU and GPU lately. My CPU is hitting 90C, while the GPU barely reaches 60C even during gaming.
- My GPU usage is about 75-80% while gaming.
- The performance drop happened right after a Windows update last night, and I'm wondering if that's involved.
I've already tried deleting the shader cache and adjusting the Nvidia control panel settings to prioritize performance, but nothing much changed. After using DDU to remove and reinstall the drivers, there was a slight improvement, but I'm still far from where I was yesterday. I'd appreciate any insights into diagnosing or fixing this issue!

Have you looked into your CPU's clock speeds during gaming? If they're not performing at their usual levels, that might be the key to the issue. Also, running a benchmark during heavy gameplay could help identify if your CPU is getting throttled down when it reaches high temperatures.
It sounds like your CPU might be thermal throttling, which can definitely impact your FPS. Since you mentioned that your CPU temperature is way higher than normal, it could be causing the downward power limits. You can check your clock speeds while gaming to see if they’re dropping. Even minor changes like a Windows update can sometimes affect performance, so it could be worth rolling back that update if the problems persist.
