          @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.

              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 :\

                          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.

                                          he already has core_freq and v3d_freq overclocked in his config.txt

                                          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.

                                            @barbudreadmon the only other two blocks of the GPU are for the image sensor pipeline (camera) and video decoding. Neither of which are useful here.
