    rx480 problems

    itssapir

      i began having issues with a game (brawlhalla) a week ago, where i opened it, the steam overlay suddenly didnt come up, and i had terrible frame rates. (instead of constant locked 60fps)

      after updating the drivers of the card the problem seemed to disappear.

      it has now started happening again, this time im noticing its not a problem with the specific game.

      when i try to launch factorio it flashes the screen a bunch of times and then says :  "failed to create display!"

      when i try to launch rocket league it says : "your video card does not support alpha blending with floating point render targets (D3DFMT_A16B16G16R16F), ......"

      when i try to launch warframe, it says : "your graphics card is not supported ........"

       

      i cant figure out whats wrong, i tried rolling back the drivers, reinstalling them, restarting my computer several times, nothing seems to work.

          I have the same problem. Uninstaling the drivers in secure mode with DDU and reinstalling again seems to fix it temporaly, but the problem start again after a few days. I only have 1 display active at a time. The problem seems to occur only in the DVI monitor, the HDTV works fine.

           

          The erros I get:

          Stellaris: Failed to create a graphics device. Exiting.

          Rocket League: Your video card does not support alpha blending with floating point render targets ...

          Don't Starve: Error during initialization.

          Rainbow Six Siege: Opens in windowed mode. Cannot change to fullscreen nor change resolution.

          Dir Rally: Opens in windowed mode. Cannot change to fullscreen nor change resolution.

          Company of Heroes 2: Cannot find supported hardware rendering device. Ensure that you meet the minimum system requirements... verify that DirectX is installed and drivers are up to date

           

          I just find this fix (Enabling GPU Scaling in the Radeon drivers for the DVI monitor [Games not working in DX9/DX11/OpenGL since 17.4.4 on RX 460 in a DVI Monitor. ]) and seems to work, but I don't know for how long.
