I short while ago, I noticed that light points started flickering after panning around at night.

It was the AMD drivers after all, and not my GPU.

This is what I did:

It was very difficult to actually get rid of a the AMD drivers. I had to use DDU in SAFE BOOT mode to finally get the job done. It was like getting rid of bed bugs. I went back to an earlier AMD Radeon driver (16.2) and all is working well with NO flickering! Also, I have disabled the automatic Windows Update install, so that I can preview if it tries to push an updated AMD GPU driver.
