      @Zering Nah, don't worry. Thanks though. I was just interested if you had given it a go. It's the worst of the lot for me.

        @AdamBeGood Have you managed to get your games running without too much hassle? I find some of them require a bit of tinkering to get the best performance out of them, ie. Tactics Ogre.

          Well, so far I've only tinkered with resolution and FrameSkip, nothing more than that. I have found some games get along with FrameSkip better than others, for sure.

          I am not sure which other settings to mess with. The only games I've really got struggle with are the ones mentioned - God Of War, Killzone and Resistance. I read somewhere that Tomb Raider was a problem,but that was fine. Haven't tried Tactics Ogre as yet.

            @AdamBeGood The resolution can go a long way, and I find that the Auto resolution setting causes worse performance than manually setting it. A few rare games run wonderfully without buffered rendering.

            The reason I ask is I can't get any higher than 20 fps on both Gta stories games, even with frameskip. They play too slowly for my taste. Did you manage to get those running any better?

              I had one running and I was happy with it, but didn't try the other one. Let me check on this, I can't remember details. I'll be back!

              Edit: I'm back. I haven't played far, but all seems fine at 2x / FrameSkip=Auto and 2 / Buffered. In both games.

              Further Edit: Have a look at https://retropie.org.uk/forum/topic/24999/getting-the-best-psp-experience-on-a-pi-4/10 - I think setting Resolution to 2x and the "Lower resolution for effects" to "Aggresive" does seem to work. There is a note that it causes glitches, but for problem games may be a winner (but not Killzone and Retribution, they seem to still struggle. God Of War: Chains seems to be a lot better but I need to play more).

                @AdamBeGood Excellent, I'll try that, thank you.

                How is God of war on your end speed wise?

                  I'm having to work at the moment (which seems very unfair), but I tried it quickly and with that setting it seemed like it might be playable, just about. I need to try for longer though.

                    @AdamBeGood I tried it myself in the end, it does seem fairly playable, as does the sequel. The agressive lower resolution for textures setting caused some serious graphical glitches for me though, but the first few minutes of both games run full speed albeit with a bit of choppiness here and there with an auto frameskip of 3 and a resolution of 1x.

                    I'm trying to get better performance out of Silent Hill : Shattered Memories now, but it seems like the agressive setting stops video from rendering during gameplay.

                    I've noticed an improvement with Liberty City Stories, but it still has some choppiness, so maybe some of my settings are wrong.

                    Good luck with work, it does sound very unfair ^^

                      I've got Chains of Olympus on AutoFrameSkip 4, 2x Resolution and Aggresive, and apart from some slight sound choppiness it seems very playable.

                      I haven't noticed any giltching. I'll try Silent Hill.

                        @AdamBeGood Could you share your settings? I'm thinking maybe the glitches come from a mix of two or three settings like the vertex option and whatnot.

                          This is for God of Wars: Chains

                          Backend: OpenGL
                          Mode: Buffered rending
                          Simulate block transfer effects: tick

                          Frame skipping: 3
                          Type: Number of Frames
                          Auto: Tick
                          Unlimited
                          Disabled

                          Postprocess Shader: Off
                          Full Screen: Tick

                          Rendering Resolution: 2x PSP
                          VSync: Untick
                          Buffer: Up to 2
                          Hardware Transform: Tick
                          Software Skinning: Tick
                          Vertex Cache: Tick
                          Lazy: Untick
                          Retain: Untick
                          Disable: Untick
                          Spine/Bezier: High
                          Tesselation: Untick

                          Upscale level: Off
                          Type: xBRZ
                          Deposterize: Untick

                          Anitsotropic filtering: 16x
                          Texture filtering: Auto
                          Screen scaling filter: Linear

                          Lower resolution for effects: Aggresive

                          Silent Hill: SM is a tricky one. Maybe borderline playable with 2x AutoFrameskip and 1x Resolution but it isn't perfect for sure. It hates more than 2x Frameskip.

                            @AdamBeGood I've tried a few different games with your settings. I'm still getting the same graphic issues with God of War ; there are white shapes on the screen that seem to shadow the movements of a couple of the enemies. Without Agressive LRFE the glitches disappear, but I have to bring the resolution to 1x. Which is fine, to be honest, I kind of like the jaggedness of original PSP graphics. It runs full speed then.

                            I can't get any video during gameplay for both Silent Hill games any longer, which is very strange. Not that it matters, they don't seem very playable ^^

                            Edit : Lunar Silver Star Harmony is another odd one. It runs fine but the text comes out of the boxes and is cut off on the side. Weird ^^

                              Origins seems okay to me, just with my default settings. Shattered Memories has dodgy sound throughout, but not too bad and it is so close to being playable. Maybe the emulator will get updated in time, it's not far off here.

                                @AdamBeGood Yes I kind of spoke a bit quickly on Origins, I'm getting some massive visual glitches in cut scenes but it is playable.
                                And agreed, I'm honestly quite baffled that my trusty single board computer can run bloody God of War ^^

                                  Thanks for the brilliant advice here! I've ordered a 2gb model and will be dead keen to get it running and start experimenting, even perhaps with Box86 also :D

                                  GUN has to be one of my favourite games of all time, thus I'm chomping at the bit to be able to play my PSP version on the big screen. I'm sure I'll look at it and think "well it DOES look way better small" but I'll burn that bridge when I get to it lol

                                    @MRKane You may be surprised. Some PSP games run great at twice the resolution, effectively making them look better than they did on original hardware. Besides you gotta love the jagginess ^^
