DirectX....

Interesting experience. I bought a new Direct X 12 video card. Installed it in my Windows 7 system. Triggered me. Removed it and put my DX11 card back in, everything is fine.

Did some research, Windows 7 doesn't have native DirectX 12. Direct X 12 was baked into Windows 10. The Windows update that renders Windows 7 unusable for me updates several DirectX files. The Microsoft consultant said that DirectWrite and DirectDraw could be candidates for what in Windows 10 is causing the issue....

Maybe for software, the DirectX is somehow the trigger.

ensete Correlation is not causation.

While it's still an active area of research and my findings are inconclusive I have reason to believe some GPUs have the internal VBIOS hardcoded to potentially always have temporal dithering on their outputs. I have encountered at least one instance of this when testing with my lossless video capture setup. This could be the case here as well.

JTL I agree that a video card can be the source of the issue even with a OS configuration that does not cause issues. I have experienced that myself.

However, my thinking is if we have a working video card and OS setup, and know how we can change the OS to not be working for us, and indentify what change is made, we may find that the change could be made in software OR hardware. So an OS change could cause the issue, o a video card change could recreate the issue in hardware.
