          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.

                                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.

                                          I don't get any TV settings to set the MHz, but the game I tried (Jet Grind Radio) loads. What I've noticed is that the dynarec might not be enabled in the config file.

                                          Try editing /opt/retropie/configs/dreamcast/emu.cfg and look for the Dynarec.Enabled line in the [config] section. If it's set to No, then replace it with yes and try running the game again.
