      @shavecat Please don't use images with showing log files, it's hard to look and search for errors. Use pastebin.com for large logs and for a few lines, just surround them with code blocks.

        it goes out , this is the image of the runcommand.
        and for the lr-flycast runcommand-

          What does this mean ?

          really slowwwwwwww

          That could be for a number of reasons - what system are you running on ? Is every game slow or just some of them ?

            pi3b+ 4.5 .
            just now update .
            before the dreamcast was running with no problems with the recast .
            and its quit with some games after picking the MHZ.

            and the lr-flycast , everything is really slow... everygame.
            any ideas ?
            or just go back to my 4.4 image save ? (will be shame )

                pi3b+ 4.5 .

                I was referring to the hardware setup you have - as asked in https://retropie.org.uk/forum/topic/3/read-this-first. Do you have any overclock ? Is your Temperature ok ? Do you get any over-voltage signs ? What's you GPU memory split ?

                and its quit with some games after picking the MHZ.

                Where exactly are you picking the MHZ ? Is this the resolution change in the Runcommand launch menu ?

                then it takes to load the game like 1 min' from then everything really slow....

                Is it for every game like this ? No matter the size ?

                  @mitu thanks for the help so -
                  Do you have any overclock ?
                  yep like before work like charm
                  Is your Temperature ok ?
                  yep 44 deg'
                  Do you get any over-voltage signs ?
                  no
                  What's you GPU memory split ?
                  120 think like before .
                  Where exactly are you picking the MHZ ?
                  after u pick a game and its start after the logo
                  u pick for the tv 50Mhz or 60MHZ
                  after u pick it exit
                  every game
                  Is this the resolution change in the Runcommand launch menu ?
                  no
                  Is it for every game like this ? No matter the size ?
                  yes.

                  IM the only one having this problems after update ? with dreamcast only ??
                  everything else works perfect. still got my image 4.4 so can always go back but will be shame :\

                      really slowwwwwwww

                      You need to overclock your gpu, 500Mhz is the bare minimum for a good gaming experience, the default 300Mhz is not enough for most games.

                        have it -

                        arm_freq=1500
                        core_freq=600
                        sdram_freq=550
                        v3d_freq=525
                        over_voltage=6
                        sdram_over_voltage=4
                        temp_limit=70
                        temp_soft_limit=70
                        

                        its only slow on the lr-flycast
                        on the recast run fine but getting quit after same games to pick tv settings MHZ.

                            No, you don't, gpu_freq is missing from your config.

                                @barbudreadmon he already has core_freq and v3d_freq overclocked in his config.txt. The other blocks of the GPU shouldnt need to be overclocked for emulation purposes.

                                      Are you sure v3d_freq is enough ? I always set gpu_freq instead.

                                      so why it so slow ?

                                      Maybe your core options then ? lr-flycast's default settings aren't for low-end device, unlike reicast's. iirc, the following settings are especially important :

                                      reicast_alpha_sorting = "per-strip (fast, least accurate)"
                                      reicast_div_matching = "auto"
                                      reicast_enable_dsp = "disabled"
                                      reicast_threaded_rendering = "enabled"
                                      reicast_cable_type = "VGA (RGB)"
                                      reicast_frame_skipping = "1"
                                      

                                      You might need to change frame_skipping on a per-game basis.
