emmet I have Intel Arc A770 LE for a couple of weeks now. I don’t experience symptoms with it (at least not those beyond OS-level symptoms). There is banding present on the output of this card in my configuration. I am symptomatic with AMD and new Nvidia cards.
The Intel Arc A770 LE feels just like integrated Intel graphics, which I also don’t have symptoms with.
If I enable dithering with the new Windows 11 Advanced Color settings (see my posts below), the banding disappears and I have pain.
I would be cautious of third party Arc cards, they could introduce temporal dithering on the VBIOS. My experience is, for now, valid only for the Intel Arc A770 LE card.
This is big for me. I am coming from an old Nvidia Quadro K5000 card.
I can also game on it on Windows 10 when I force Fullscreen Exclusive (FSE) mode by disabling Fullscreen Optimizations and verifying using PresentMon (game.exe frames should be logged as “Hardware: Legacy Flip” if your game is running in FSE). Fullscreen games that only offer a borderless window can probably be forced Fullscreen Exclusive using Special K. My OS-level strain (because it is experienced on all cards, good and bad) is greatly mitigated in FSE. PresentMon is very useful as you can actually check the presentation mode of a running application and compare symptoms.
EDIT: for clarity
