posting this from the super metroid thread: i have trouble to watch a bkm.. or even play super metroid on this new bizhawk thing.. ive installed pre-reqs .net 4.0 and then a fresh bizhawk when i load super metroid it runs with 21~ fps and the sound awfully stutters and lags what must i do? (i dont think its my PC-specs 2,6ghz dualcore/8gb ram/512mb gfx card/ssd or?)

Disable Rewind. That should help the FPS.

There's no way it's his specs. I have 2gb RAM, 224mb shared VRAM and 1.8 GhZ dual-core, and I get 50 FPS with no movie, everything at minimum. (which I understand incurs a lot of CPU overhead; with movie i get like 30.)

Same problem here. I get 20-30 fps watching the demo, 40-50 with rewind disabled, and the sound stutters. I have a laptop with a 2.2 GHz dual core cpu and 3 GB ram. Not the fastest, but smooth emulation of SNES games shouldn't be too much to ask for.

the snes compatiblitycore process is running with 30-50% cpu usage is that also intended? or maybe thats the cause?

quad core 2.93 Ghz 64 bit OS, run full speed during metroid playback and about 80 fps during fast forward, with rewind disabled. About 15% cpu usage (of a max of 25%, don't think bizhawk support multiple core?). Doubt amount of memory or graphic card spec matter much for snes emulation with today's computer. 50% on a dual core means its using a core to its full potential, not the cause but the result. I do believe OP's spec should be sufficient for real time playback, if you can't figure out the problem, you can always dump the AVI and do something else in the meantime, using FFmpeg/XVID setting on my pc, its encoded in real time, so shouldnt take much longer then watching the movie itself.

Try higan/bsnes and RetroArch (64-bit if possible, and use the built-in updater to download the bsnes "balanced" core - "performance" is outdated). I get 150-160fps with that on my AMD when I disable audio sync. Also make sure your graphic card's hardware acceleration is used (i.e. never use GDI mode).

Same problems here, but worse. I have all the prereqs including .Net 4.0 and decent specs outside of my Gfx card (2.33 Ghz dual core, 3 GB RAM, Intel Graphics Media Accelerator 950). I disabled rewind but that barely affected the FPS. The screen displays high FPS (53-57ish) but the sound stutters like crazy and the gameplay clearly doesn't match the claimed FPS. Looks more like 20 FPS at best. Fast forward and turbo don't do anything. The bkm movie I tried played at 38-42 FPS and advanced at a snail's pace. Sometimes the sound stutters so much I think the program is crashing. Frankly it's painful to watch. Probably more appropriate for another topic but my initial thoughts of Bizhawk: Ambitious but why on earth is this replacing SNES9x if it doesn't even run properly on lower-end PCs? Edit: Runs much, much smoother on the performance core (under SNES -> Options)... But also caused a desynch in movie playback :( Bleh.

Was gonna write a big post, but decided against it, as it probably been discussed elsewhere. It all boils down to accuracy, or as accurate as can be at the moment and is open source, and tool provided to TAS. Bsnes core doesn't require out of this world specs, my 3yo pc runs it fine with rewind enabled.

Glitchy TAS of 2013 Gameboy TAS of 2013 PSX TASer of 2010
I posted in that topic ( http://tasvideos.org/forum/viewtopic.php?p=345521#345521 ) but I don't know for sure if it is the same problem or not. I am getting very low fps with BizSNES 1.4.1 (0.25-1 fps) when I would get at least 20-30 fps with 1.4.0. I don't know what is the cause of it.

All consoles on BizHawk run at 30-50fps for me, not SNES alone.

If you are building the latest SVN revision, make sure you build it in Release config not Debug. If that's not the case, then I don't know. Uncheck Config>Gui>Use GDI+ Display method (that makes everything run slow for me)
