Symptoms after windows 10 update to 21H2

ensete This is incorrect. Microsoft often updates system files, including functions related to the display (especially DirectX/DirectDraw/DirectWrite)

This is very true, but we have tried extensively over a decade to find a link between this MS graphics architecture and our problems and haven't as yet. I have even had dialogue with the graphics team at MS that deals with WinUI and the like, without any fruitful possibilities as to how it could in any way affect dithering etc.

However for many, including myself, switching between two graphics drivers can trigger symptoms and 'eye jittering' instantly.

So it's at least worth a try! After being stuck on Windows 1511 for what seemed like forever I am now successfully using fully updated Windows 11 but with my old drivers from 1511 and it is as good as I can get it. And I know others are similar.

Could you remind me again the version of your old drivers and the name of the video chip ?

All the info is in the original post over here. Hope that helps.

si_edgey  I did have a period where I started getting headaches again, and I noticed that dithering was periodically being enabled at seemingly random intervals, but probably because some request was made to the graphics drivers. I realised this was happening because my desktop background (colour #c84141) shows banding when everything is set up correctly, and no banding when my display is problematic for me

Sorry for repeating my question. If I understand you correctly, you have a banding on a desktop wallpaper from one solid color c84141 ? But how is it possible if only one color is used? ..or OS (Win 10) adds some post-processing/effects(??) that increases the number of color gradations?

Liberator005 No one knows what the problem is. That's the issue. There are cases of people getting symptoms and not getting symptoms for every GPU/OS/Driver combo out there.

I have spoken with the engineering team at MS as well. They have confirmed the graphics stack in Win10 is much different than Win 7, especially with DirectX

I use Rufus to install win10 1709, that works perfect for my eyes and the nvidia driver " 419.17-desktop-win10-64bit-international-whql " that also works perfect for me - I also use AOMEI Backupper to backup my full system so any testing I can quickly wipe and take my pc back to a working state again.

I updated my glasses a few months back and was able to update to the latest version of windows but it was short lived, all the symptoms came back.

I wish I had an answer for that! Perhaps the specific colour I chose requires dithering to be displayed, or perhaps it's some other bug in the drivers - sadly everything that is said on this forum has to be qualified as being individual to one person as the condition(s) we have are neurological in nature.

Placebo is also incredibly hard to rule out in many cases, including my own. Delayed onset (and offset) of symptoms mak it almost impossible to diagnose exactly what is going on, you just have to find what works for you and stick with it.

diop I use the latest Firefox all day every day. It has improved since quantum first came out. I recommend the use of a dark theme, try alpenglow which is one of the bundled options.

For video playing I currently use d3d9 overlay in the madvr renderer along with matching the panel refresh rate to the video eg 23.976. Basically I just upscale chroma with the renderer and have the monitor do the scaling instead of having the gpu do both.

si_edgey Can you share your 1511 drivers? Thanks. How on find them?

mrmarkyuk Do you have security updates? Or you block them as well?

si_edgey How one can get old drivers from 1511? Thanks

ryans I noticed this today when I was testing different builds on the deck. My regular PC is still 20H2. I noticed right away that 21H2 was different. Maybe more saturated?

Liberator005 I don't think it's placebo. It's real. It happened to me too. I carried on and adjusted, although the previous version was probably easier on my eyes. It took weeks. I'm now having the same issue with 22H2, but this time I didn't put up with it. I reversed the install. You can easily do that from the Update History. The problem is that my IT admin keeps forcing the update every week, so at a certain point I'll try to adjust to 22H2 too.

AGI @Sunspark It's different for sure. I am hoping, I can adjust...
