        Thanks for helping

        "HD" games are running smoothly (PS1, DC, PSP), it occurs into ES menus and with SNES and MD for example.

        Here is my config.txt

        uncomment if you get no picture on HDMI for a default "safe" mode

        #hdmi_safe=1

        disable_overscan=1

        uncomment to force a specific HDMI mode (this will force VGA)

        #hdmi_group=1
        #hdmi_mode=1

        comment to get jack audio

        hdmi_drive=2

        Using /etc/modules is deprecated and no longer supported on 4.4 kernel

        So manually enable audio

        dtparam=audio=on

        config_hdmi_boost=0

        force hdmi while the tv can take time before sending the signal on the hdmi output

        hdmi_force_hotplug=1

        uncomment for composite PAL

        #sdtv_mode=2

        uncomment for lirc-rpi

        #dtoverlay=lirc-rpi

        if you plug your tv at the same time as your rpi and that the rpi switches from the hdmi or give a low resolution because tv had no enough time to initialize it

        boot_delay=3

        uncomment if you don't want the rainbow at startup

        disable_splash=1

        Overclock

        gpu_mem_256=128
        gpu_mem_512=256
        gpu_mem_1024=512

        avoid_safe_mode=1

        kernel=zImage

            I don't understand your question, what do you mean ? (You may tell in French, I posted here to have more advices but I'm French-native too ;-))
            I use this image on a GBPi3, it is exactly the same image I use on my Nespi on TV without any problem.
            So I assume the problem is with the GBPi3 screen

              @Pegoncology you should have post your question in french in the french section. Don't forget that the devel team is mostly french ;)... so the support can ben in french too 😉

              anyway, @Substring is asking to run the tvservice command on you Pi to see the detected video mode :

              # tvservice -a -s
              state 0x12000a [HDMI DMT (35) RGB full 5:4], 1280x1024 @ 60.00Hz, progressive
                   PCM supported: Max channels: 2, Max samplerate:  48kHz, Max samplesize 24 bits.
              #

                        @pegoncology Can you enable DrwFPS and make sure all runs at 60FPS ?

                          bool name="DrawFramerate" value="false" to "true" into es_settings.cfg ?

                            @pegoncology no, you can do it from the ES menu, in advanced settings i think

                                  Yes sorry, that's what I did. It shows well 60fps.
                                  But when on ES menu, if I change system and if it is the "first" time I go to the system page, it shows around 40fps then it goes to 60fps in 1 sec. Afterwards I go back to this system and it is well 60fps

                                    @pegoncology it's not stable on more powerful boards, don't worry

                                    now for your screen ... too bad, i'd say 😕
