This is annoying. I don't know if I am more sensitive now, or if something got glitched.
This is on Windows 10 w/ Broadwell drivers.
What I observe is more shimmer and when I run ditherig the picture becomes more stable.
My monitor is FRC/temporal dither and with the driver, it's doubling it so it's more noticeable.
It's not my imagination. Ditherig is working on my external monitor. I'm not sure why. Maybe because the motherboard is basically a laptop board.
