    Hello All,
    In last Friday i bought Gigabyte 5700 XT Gaming OC. Pc is new.He has 3 week:)

    Ryzen 5 3600
    Ram 16 gb 3200mhz
    MSI X470 Gaming Plus Max(Bios has been updated)
    Corsair VS650
    Win 10 (all updates installed)



    After installing the latest Adrenaline drivers, the circuses began. The games had faded colors. (For example, the World of Tanks looked like it was still smudged). The colors were set to FULL RGB. And there was some strange pixelosis (As you can see in the photo below. I uninstalled the new drivers via DDU and I have uploaded some old ones. The colors have improved but the pixel shadow effect has remained. I was looking for info on foreign sites and all they offered was to remove new drivers what I did. After changing the drivers I see GPU Z showing me some weird clocking. On new drivers it showed 1750mhz. ( I don't know if it should be like this) Do you have an idea how to deal with these problems?
    Thank you in advance.

    That looks just like a alpha test shader used on vegetation for performance reasons (avoid alpha calculations, so dithering is used instead and it shows when large areas aren't 100% opaque instead of just on their borders), it can be seen on many games. Temporal AA or post processing AA should help disguise it on movement, but not just MSAA. I haven't that game, so I might be wrong.

    Nvm, I'm too used on Assetto Corsa's shaders AT blending param resulting in dithered alpha. I meant it (alpha dithering) vs the more demanding alpha blending on my previous post.

    Hello Piotr,
    reinstalling windows won't help.
    What you can try is download reshade
    https://reshade.me/
    Enable deband shader (you will need to play with settings), it could help with masking dithering.

    Doesnt work:(

    I noticed that when I change the graphic settings in games with medium it is ultra ... The graphics are the same ... does it mean that the card is broken?

    The clocks reported by GPU-Z are indeed strange; is the card brand new?

    Hi and welcome new user from Poland ;).

    I also have RX 5700 XT. Try to use 19.9.2 driver, this should repair problem with strange memory clock. This graphic bug looks like .. aggresive Radeon image sharpening ?
