Okay, so at first I thought that this trick only works if you have an integrated GPU. Where you connect your monitors to your motherboard instead of your RTX, do some registry changes and the RTX does the work load and your iGPU gives the output but undithered. But a few days ago I learned that it works even with a second GPU and no iGPU. So I used my GT1030 which I have been using with no eye strain for years now along with my RTX 3070ti and the trick seems to be working. A few things I wanted to ask though about your experience with the trick:

1- Anyone else tried this method? Is dithering really fully gone, and do you get no eyestrain?

2- I can't seem to get the game "Control" to run with DX12. When opening up the DX12 instance it crashes, so even though it is using my RTX as the card of its choice, I can't enable DLSS or Ray tracing. Any way to fix this?

    BloodyHell619 Can you describe the trick? You attach your graphics card to the motherboard but use VGA on the integrated graphics and this somehow (perhaps) disables dithering?

        ryans If it's what I think it is, it's forcing the display output to the integrated GPU and attempting to utilize the dedicated GPU just for 3D rendering.

          I don't know if I might have done something wrong, if Nvidia might have done something with its drivers or my windows is too updated or if my eyes were just tired from using my Galaxy Note 5 or from the cold I am catching or if I've simply just gone crazy, but it was still straining my eyes pretty bad. I tried connecting my monitors to the card itself and compare and honestly visually I couldn't see any difference. I gave up and pulled the card out again. 🙁

          This is interesting, can you link any guide you used or was it just a case of two Nvidia cards and connect monitor to the 'good' card and in Windows set the application to use a specific card?

          I would try this but I've gone AMD now and dont want to risk wiping out my settings that are mostly working now. I still have a couple Nvidia cards so I'll maybe have a look for 2nd hand parts to test with.

            This comment is where I learned how to do it

            I installed Atomic Heart and played it with this method. Some really weird stuff was going on with the RTX reflections and Light rays. Certain object's reflections in water would flicker as I moved. There was also a beam of light coming through a cracked roof at some point, and it consisted of many huge pixel blocks. Shadows also had a weird pixel trail at the edge of them that even flickered in some places. I wish I had recorded it, but I forgot and pulled the card out. Something was definitely going on. Tried connecting the monitor to the card itself and the same stuff was still going on. I have actually contracted corona today. What a pathetically stupid timing. Maybe my eyes strain and burn was for that, though I doubt it. I'm really interested to see you try it and see if you get the same experiences.

                Sunspark I think the flicker and pixelation I was witnessing in Atomic Heart might not have to do with the dithering. At first, I even thought my card might have become faulty, but from what I am reading it seems to be a conflict between AA antialiasing and Ray tracing that causes those artefacts. I might give the card another try later on if others here test the method and find it to work.

                  6 days later

                  I put in the card today for a second time to try another trick I thought of. I decided to set the RTX as the "power saving card" by adding the string "EnableMsHybrid" to its registry and setting its value to 2 and make my gt1030 my "High performance" card adding "EnableMsHybrid" to its registry and setting its value to 1. By doing those, I was clearly able to observe from task manager that the RTX was doing no work when in windows itself, so no eye strain at all there. To get the RTX to do the work this way, though, you have to set each app to use the "power saving card" as the card of choice yourself under Display Setting --> Graphic Settings. This way even more games failed to work. Atomic heart didn't work, for example. The 2 games that I got to work perfectly were the RE4 Remake Demo and PES2021. Sadly, though, after playing RE4 Remake for barely 30 minutes, I felt the most horrid headache and nauseous feeling I had ever felt in my life. Like my eyes were about to explode instantly, So sadly I think the card still dithers. 🙁 Hope to see someone else give this method a try and see if the same applies for them too.
