Sorry to hear it didn't work.

I think Ditherig only works on Intel GPUs.

  • JTL replied to this.

    AgentX20 Dihterig theoretically has functionality for some AMD GPUs, but if it actually does anything with an implementation on a given chipset is a different question.

    @AgentX20 Yes as @JTL said v2 of Ditherig now also supports some AMD GPUs.

    @JTL @AgentX20 Do you or anyone else here know any AM4 socket AMD CPUs with integrated GPUs that don't dither at all?

    By the way, today I tried one more thing which didn't work either. I installed Linux mint on my local drive and switched its driver to NVIDIA so that I get the dithering option and from there I disabled dithering, but it made no difference.

      BloodyHell619 @JTL @AgentX20 Do you or anyone else here know any AM4 socket AMD CPUs with integrated GPUs that don't dither at all?

      I've never tested those so I can't comment. Sorry.

      BloodyHell619 I had a ryzen 1700 + RX480 that was perfectly fine with some W10 version like 1809 and previus and 21H1.
      Then I tried to change the CPU and mobo with a ryzen 7900 and i am not able to use that system more then 30 minutes. I've tried to clone the old SSD in order to have the same OS / driver, tried different GPU the integrated one, RX480, 970, 1660 SUPER and 4070, nothing work for me.
      I am convinced that the problem is the MB/BIOS.

        Just to make sure, check that the software dithering is 100% disabled through the registry since it has a habit enabling itself again, i noticed that with the Nvidia disable dither registry key that if your monitor goes to sleep or if you turn the monitor off and on again it will revert to temporal dithering. First disable dithering from the post here https://forums.guru3d.com/threads/nvidia-and-dithering-controls-how-to-enable.436621/ and then download ColorControl from here https://github.com/Maassoft/ColorControl. ColorControl will display your current dithering status and it will keep the settings locked in.

        Lauda89 This is what horrifies me. Even though I have placed my card in another system, and it still gave me eye strain, I feel like it's something I got baked into the motherboard that infects every card I put in my system and this is so devastatingly sad because I literally have to trash this pc and get a new one whole.

        @Jack Yes sadly I have tried all those methods and registry hacks and sat behind my pc without turning my monitors off, but the disgusting pain was still there.

          Any chance you could dig out an older firmware for your video card and refresh things at that level? (They can be rather hard to find these days, and it is complicated by some cards having not one but two VBIOS slots).

            I know for a fact, having bought and sold multiple of these video cards that they're not all the same. Of the dozen or so G1 Gaming 970 cards I've owned:
            ...

            • V1.0 hardware is a lottery - Hynix RAM is A-OK, and Samsung RAM is bad (they get sold too).

            I was actually thinking about buying a G1 Gaming 970 after reading about your experience, but I must admit now I am a bit confused: In this thread you seem to state the opposite:

            You may be right, but I have had multiple Gigabyte G1 Gaming cards, and there certainly seemed to be some sort of correlation.

            All of them (2 or more) with Hynix ram caused eye strain.

            All of them (3) with Samsung ram were OK.

            So I am wondering are the Hynix or Samsung ones working for you?

              Garman So I am wondering are the Hynix or Samsung ones working for you?

              Sorry about the confusion. I hope my observations have been consistent after all…

              I'm currently starting at a Hynix based 970 G1, so pretty sure it's the Samsung ones that I've found to be 'bad' (for me).

              What's also important is to find V1.0 hardware. It's on the white box label and also on the card near the slot connector.

                Thanks for the update. I was indeed able to find people selling this GPU, where the revision number was visible in the product image of the card, so a version with rev 1.1 should be easy to avoid.

                What I was wondering: Is there any way to determine the memory type aside from running GPU-Z? Asking a seller to look for the revision number in case it isn't visible shouldn't be a big deal, but I am wondering if people will be willing to reinstall the card and take a screenshot with GPU-Z.

                  Switched lightning setup in the room since the last time it worked fine? Move the computer by the window, test the devices outside.

                  In my experience (from Mac at least) you can test with a lot of stuff by simply disabling hardware acceleration in Chrome and using that full screen for a while.

                    Then I upgraded the BIOS on the old motherboard with the intent of putting a 5800 on it and it became inusable as well, even going back through the BIOS.

                    I'm not entirely clear, did you manage to return to the old BIOS version?

                    could you please tell me the motherboard model, old bios version and new bios version?

                      glvn The MB is the Crosshair VI Hero. The BIOS that fuck up my good setup was the 8701, then i roll back to the 8002 (the starting point) and then i tried to roll back to something old like 1701 or something like that, i don't remember in this moment. Are you able to find the difference between 8701 and 8002? 🙂

                        return to the old bios returned (normalized) the situation with eye strain?

                        Are you able to find the difference between

                        unfortunately no 🙁 I'm just trying to understand: if the version of the main BIOS affects eye strain, is it possible to definitely fix the situation by returning to the old BIOS?

                        for example, on the Intel platform, an unambiguous return to the previous version (by regular means) is not always possible: https://www.asrock.com/MB/Intel/Z370%20Pro4/index.asp#BIOS

                        "* User will not able to flash previous BIOS once upgrading to this BIOS version."

                        As I understand it, this is due to updating ME (Intel Management Engine) as part of the BIOS. What is the analogue of ME in AMD and whether this component affects eye strain is an open question for me ..

                          glvn No that PC is still not usable for me unfortunately. So now i am using the new PC 13700K+RTX 4070+W11 21H2 with patching my right eye, and is almost ok but still not usable with 2 eyes.

                          To downgrade the bios, I followed this guide: https://www.youtube.com/watch?v=DwJS8-GTgRU

                          Sadly it still strains me massively in day light and with no lights on at all.

                          Honestly I even tried flashing VBIOS's of other cards onto my card but it still made no difference.

                          So I had my brother bring me a CPU with integrated GPU compatible with "Ditherig", a Ryzen 5700G CPU hoping that I could disable the dithering using "Ditherig" but it made no difference. I am in utter aw and broke as hell. Whatever the heck is going on is at the motherboard level. The strain is also definetly there even in the bios screen. But What I don't get is why does my GT 1030 strain me when used in another system?

                          It feels so stupid to have to go and buy the exact same motherboard again. And there's so many factors to take into account as to how to set it up then. I'm really fucked up. Should I put my old CPU in it or my new one? Should I buy a new GT 1030 too? What a freakin hell of a situation….

                          I also used a microscope my brother brought me on my monitor to check for dithering and it clearly is dithering horrifically. Can't post the video here.

                          Tried the same monitor paired with my dads old laptop that doesn't dither and the monitor wasn't dithering.

                          I could almost see the screen dither and when I read text on it for many seconds afterwards I see after-images, horizontal lines crawlling down everywhere I look.
