      @mrpacman17 try forcing software mode by editing file /opt/retropie/configs/all/retroarch-core-options.cfg

      replace line

      duckstation_GPU.Renderer = "OpenGL"
      

      with

      duckstation_GPU.Renderer = "Software"

        do you have any particular examples which slowdown with the default hardware (OpenGL) renderer on pi4? ideally with a way i can quickly verify them.

        in lieu of vulkan i can be tempted to make software the default renderer for pi4 (and pi2 and 3?), but i haven't seen any performance issues in my (limited) testing of the default hardware renderer - open to ideas!

        i note that a few of the PGXP enhancements are on by default - i'm not sure if they are applicable to software mode, but if they're not i would be tempted to turn those off by default if i can provide full performance.

          @dankcushions Hi there.

          Thanks for the advice but it doesn't work :(. What is strange that the file you mentioned contains NO other entries for Duckstation what so ever.

          See pastebin for the verbose log of Runcommand: https://pastebin.com/LXzAgGwS

          And pastebin for the retroarch-core-options.cfg: https://pastebin.com/e8p3jr7E

          Guess something is not okay here. And thanks a lot for your help here, much appreciated.

            @dankcushions I've tested a handful of games on the Pi4 (arm 2000/v3d 700) and found:

            OpenGL
            All tested games seem to run full speed at 1x native with or without PGXP enhancements tested more and it seems PGXP can cause slowdown in certain scenes. It's not terrible, but it's definitely there.
            1x native with any form of antialiasing introduces slowdown in certain scenes, with or without PGXP.
            2x native and higher introduces slowdown
            Some of the time the emulator fails to initialise the OpenGL renderer, simply trying a second time with identical settings seems to fix it.

            Vulkan
            AFAIK, Vulkan is not officially available in RetroPie yet, at least on RPi platforms.
            [ERROR] Requesting Vulkan context, but RetroArch is not compiled against Vulkan. Cannot use HW context.

            Software
            Everything seems to run full speed.
            Scaling, antialiasing and PGXP are not available in software.

              @mrpacman17 Turn on logging in retroarch and post that log. Settings - Logging - Log to file.

              Logs should appear here:

              /opt/retropie/configs/all/retroarch/logs

                @mrpacman17 can you please show your config files:
                /opt/retropie/configs/all/retroarch.cfg
                /opt/retropie/configs/psx/retroarch.cfg

                  that's right - it's nether included in raspi pi OS yet, nor does retropie compile retroarch for vulkan on pi platforms

                        this is a non-default config, unfortunately. i would reset it by updating retroarch, which will generate a retroarch.cfg.rp-dist default file in th same folder. delete/rename your old retroarch.cfg and then rename retroarch.cfg.rp-dist to retroarch.cfg

                        that said, the line i was curious about is

                        video_driver = "gl"
                        

                        try instead with

                        video_driver = "glcore"
                        

                        From PSX folder: https://pastebin.com/yJqykEM0

                        looks fine

                            @dankcushions I did as requested. The file is default now and I changed the videodriver to glcore as requested. But the issue persists, see Runcommand log: https://pastebin.com/YcmcpvLM

                              @mrpacman17 glcore is not supported on a Pi4. Use gl as the video driver. Also, RetroPie doesn't support running it in a desktop session on a Pi, you should run it outside the desktop environment.

                                  I see, even this way glcore would not work. According to HP's spec page, the GPU included doesn't support OpenGL 3.3, which is needed for glcore.

                                    @mitu Okay, video is set back to GL. Still no luck though. I am doing something wrong but I don't know what. Sorry for my basic level of understanding here.

                                        @mitu we tried that :) i believe even in software mode duckstaiton needs a valid gl context. methinks this hardware is getting nothing. perhaps a linux driver issue. nah it should fall back to software... https://github.com/stenzek/duckstation/pull/908 - weird.

                                        @mrpacman17 i'm afraid i'm out of ideas. i don't have this hardware. if you know how to use gdb you could get a backtrace of the crash. you could also try the libretro and duckstation discord for advice.

                                          @dankcushions Hi all. Well I am not a Linux specialst whatsoever. So I leave it at this. Thank you very much for your time and effort. I really appreciate it. I will run my PSX games with another emulator. Still I appreciate all your hard work. Thanks to you I can play retro games, which is totally awesome!

                                            @dankcushions and @mitu: It WORKS!!! Just for a last effort I added the line as I did before. And now it WORKS!!! Totally happy I am. Guess all the previous steps combined with the software rendering did the trick. Woohooo!!! Thank you guys!
