Hello,
I initially had a 2060 RTX paired with a 13700K, and it ran games really well. After upgrading to a 4070 Super, I noticed lower FPS than I expected. Following a YouTube tutorial, I performed a DDU (Display Driver Uninstaller) to clean the installation, but it made my GPU performance worse. My games started lagging, and GPU usage spiked to 50% even during non-intensive tasks. I reverted to the 2060 and decided to do another DDU, but now that GPU is also underperforming. My games are consistently freezing and experiencing low FPS. What should I do?
DDU is breaking my gpus

It seems more like an issue with your windows installation.stephaniecox wrote: ↑Thu Jun 12, 2025 4:53 am Hello,

Try to Refresh / re-install your windows. (this totally revert what DDU did).
"GPU usage spiked to 50% even during non-intensive tasks" That is normal and expected when doing non-intensive tasks, the GPU lower it's clock and then the % usage goes higher since the card intentionally went at a lower speed. (can be workaround by setting "Prefer maximum performance" in the nvidia control panel.
