Recalbox 7.0

PSX emulation is incredibly slow



  • As said. PSX emulation gives me like 10FPS. Picture is frezeeing, sound is frezeeing. Smoothing is OFF, rewind is OFF. Recalbox installed on Zotac ZBOX AD02 Plus (AMD Dual-Core E-350 1600Mhz, Radeon HD 6310, upgraded to 8GB RAM and SSD) which I consider way more than enough to give back some smooth performance. What should I do to fix that?

    @zzapzzap it is not that good, only one core is used anyway and it is likely graphic card isn't either. did you activate any kind of enhancing ? if yes disable it, it is very costly.

    If you're on the latest stable release, try the beta or wait for next stable, pcs are/will be much better supported on it



  • @voljega How do I update to beta? If I switch "Update type" from Stable to Custom it won't save and switches back to Stable. And if I swtich from Stable to Beta through web-interface, it also won't save. Btw switching to software render helped a lot, but not completely solved my problem, still too slow to play.

    @zzapzzap you don't update to beta, you install it and you won't ever be able to update from it. If you do it please read beta thread first message carefully 🙂

    That cpu sucks for PSX emulation, single thread performances are barely higher than a raspberry, and it's not an arm cpu so it won't benefit from the arm dynarec. Without an arm cpu, a cpu of ~2.4Ghz is the bare minimum for PSX emulation.



  • @barbudreadmon That's bad. Zotac had a product lineup full of devices sharing same cases with same drilling etc. I could easily upgrade by getting motherboard with Atom D525 / ION2 or Atom D2550 / GT610 installed. Makes sense?

    It would be the same issue, as i said if you want to play PSX and don't want to use an arm cpu, you'll need a cpu @ 2.4Ghz as a minimum. If you don't plan to play something "higher" than psx, you should use a raspberry.
