I wanted to make a quick post (that can maybe be stickied) and list the fixes/hacks to get around temporal dithering in Windows. Since FRC/Temporal is my biggest eyestrain inducer (other than stupid LED light spectrum issues) I have a strong vested interest in this topic.
So let's start.
Solution 1: Buy an nVidia card, or a laptop with nVidia chipset.
This is not always an easy thing to do. But on a desktop at least, $100 gets you zero temporal dithering.
Solution 2: Disable temporal dithering for ATI.
Thanks to the guys at Amulet Hotkey, there's a solution for Windows to kill temporal dithering on ATI/AMD cards, it's a registry edit as follows (this information is from 2014, registry values don't always maintain their functionality, YMMV):
- Find your Catalyst 2d Driver registry path (in Catalyst Control Center, go to preferences->advanced->Information->Software)
- Run regedit, browse to that path.
- Look for the target key, which is either 0000 or 0001 (or both, if you have enough outputs).
- In that key (or keys), make a new 32-bit DWORD named DP_DisableDither and set it to 1.
This should shut down temporal dithering in Windows for Radeon cards of the current generation.
Solution 3: Disable temporal dithering for Intel chipsets.
There's a driver, in Chinese, here:
It's called "ditherig" and it is supposedly great. I haven't tried it.
