My HTPC has a slow AMD E350 CPU. So I was trying snes9x next, but with this core I have some graphical glitches on 720@60 (1080@60 is slow as hell on my system).
Which of the SNES should I prefere for my slow system? Is the higan-performance profile faster than snes9x?
Higan-performance would be far slower than either SNES9x or SNES9x Next.
SNES9x Next is a speedhacked and totally modified SNES9x 1.52 core - if that is still too slow for you the alternative perhaps would be a 1.43 core with some speedhacks - I don’t have that core yet as a libretro core and last time I checked SNES9x 1.50 on libretro, it wasn’t really any faster than SNES9x Next (in fact, the opposite with Yoshi’s Island spinning island screen) - and this is with the old APU that is supposed to decrease system requirements a lot.
For the record, I doubt right now you can find any regularly maintained version of SNES9x out there that would be faster than SNES9x Next. I looked for it before starting out with SNES9x Next and other than things like PocketSNES (which is butchered to hell and has numerous PPU bugs) there was really nothing out there. SNES emulation will probably always require higher system requirements than other systems.
With SNES9x Next I can at least guarantee that nearly all of the games except for Yoshi’s Island (SuperFX2) and pseudo hi-res Kirby’s Dreamland 3 (SA-1 - at certain stages it might drop a few fps) should run at fullspeed on a Celeron 733-class CPU (Xbox 1) - and on Wii (which is a bit faster than the Xbox 1) even Yoshi’s Island runs at fullspeed.
1080p might simply be out of reach on your particular system. If things run fine on 720p I would suggest sticking to that - you might get more input lag though if this isn’t your HDTV’s native resolution.
That’s odd. I have an E-350 in my laptop and it can run 720p snes9x-next just fine, even with heavy-duty shaders. It can even run bsnes-balanced at full speed on non-special chip games, IIRC. If you’re having graphical glitches, I would recommend at least trying the bsnes cores.
Any x86 CPU not from the stone age will run snes9x-next fine. If 720p/1080p is slow, you’re probably GPU bound for some reason.
With snes9x next i receive those artifacts.
Edit: Those artifacts are only occuring with snes9x next if cropping overscan is disabled.
Edit: Maybe I should try to disable Desktop Composition for better performance on 1080p. Or does it not affect at real fullscreen.
Eesh. So basically the PSP is screwed SNES-wise if RetroArch ever makes it to that platform. I know its current port of Snes9x is buggy and unoptimized as all hell, but it’s just so slow on quite a few non-special chip games. Can anything even be done about this?
SNES9x Next on a hypothetical RetroArch PSP is a definite no-go as the PSP is even slower (much slower infact) than a Gamecube or Cortex A8 Android tablet - and even the latter struggles at running Donkey Kong Country at fullspeed with SNES9x Next.
It’s probably best to give up on SNES9x ever running fullspeed or even acceptably on PSP - you can buy quite cheap portable handheld devices these days that could do that job - no need to stick around with a (now dead) platform for that sole purpose.
