All the nvidia cards bar the gtx660 I use everyday cause me strain, all the nvidia cards had temporal dithering. Not all strain me equally though, other 600 series cards strain me, but I'd say half the intensity of the 1060 I have tried. I think the temporal dithering on the gtx600 series is a bit subtler perhaps, enough that I've been able to adjust to it over the 6years i've had it. However, I have found no actual evidence that it is subtler.
No temporal dithering on intel integrated graphics. The only way to make it dither temporally appears to be enabling that feature in the ditherig.exe options. I have one office pc setup that I can use with intel integrated graphics, but another pc at home that I can't. Right now, I am wondering about the intel graphics defaulting to 59hz on my monitors. I don't think I can perceive any kind of difference that small, but it does seem possible some of my monitors are misbehaving because they are optimised for 60hz input. No point trying that today though, my eyes are pretty sore from looking at bad graphics cards all day.
Really does beg the question, if not temporal dithering, why do so many people get discomfort with intel? Perhaps I should try the test again with something like a web browser open and see if the results change.
