      Hello,
      I just downloaded the RetroPie image and uploaded it to my Rpi4 only to see a constant ot 15 fps. I don't know what is causing it and as I'm new to the whole RetroPie thing I don't know if it's just some basic problem that can be fix easily or is it something else. I will very much appreciate your help.

          Model: Raspberry 4
          Power supply: 5V AC ADAPTER, 3000mA, input: 100-240V ~50/60Hz 0,3A
          RetroPie version: 4,6
          Built from: Pre made SD Image on RetroPie website - "retropie-buster-4.6-rpi4"
          USB devices: Bluetooth 2.4ghz dongle for a set of a keyboard and a mouse
          Controller: PS3
          I did not follow a guide as I have flashed images before and I thought this was no different, correct me if I'm wrong
          I'm getting low fps on the main screen and have only tried psp emulation and there I get 30 fps with some drops every now and then.

                Add the following to your config.txt and then reboot, see if it makes a difference.

                hdmi_group = 1
                hdmi_mode=16

                    Actually, it did work but instead of adding these lines I uncommented the same in the config file and just changed the values. Thank you very much for you fast and adequate response.
