      Is it normal to have shader lag on Pi 400 with the latest version of Recalbox? Mame, Megadrive, etc are laggy with shaders applied?

      Ideally I’d use the Retro shader setting which applies the community selected shaders per system. First game I tried on Megadrive was laggy.

      I read somewhere to make sure Rewind was unchecked, but this made no difference.

        it seem it's an issue with the new RPI driver
        until it will be fixed, you should use another shader than "retro"

        You can try CRT Caligari (very close to retro effect)

        I have edited some CRT shaders here, have a look !

          @airdream Thanks I thought there was an issue somewhere. I had no issues years ago with older Pi”s and older versions of Recalbox.

          I will try your suggestions.

          Again I appreciate the reply. Thanks

              So maybe you have a preset that it cause the lag
              Do you have enabled rewind function? or "run ahead" in Retroarch? changed output resolution?

                  I am not sure if rewind function is by default or not
                  It's better to disable it
