Occasionally the window performance lags, but it's hard to pinpoint the exact moment. For instance, when watching a 4K YouTube video, Windows slows down, yet CPU usage remains consistently low, staying between 30-40%.

It’s best to restart in safe mode and use DDU to clear all previous Nvidia/AMD drivers prior to replacing the GPU: https://www.guru3d.com/files-details/dis...nload.html.
