Slight issue with the system. I kind of thought games weren't running at the proper speed, and it turns out I was right... they're much faster if you run them in the PCSX emulator included in RetroArch. I've replaced the internal emulator with the one in Bleemsync, ran the emulator included with Autobleem, and changed the CPU clock setting in PCSX.cfg to 54, yet I'm still noticing a gap in performance. What's happening, and how do I fix it?

Something along these lines. (There a case is mentioned, when games break their intended fps ceilings - but normally they shouldnt.) Thats really the only major difference (retroarch extreme core afair defaulting to cpu clock 75), between stock and retroarch cores that could explain it.
Have region set to auto, dont force NTSC on PAL games (that would produce similar issues). Have CPU clock at 54% (if thats default on non optimized cores, dont remember off the top of my head
) at first. Try to force PAL on PAL games, and see if that solves it (core options, while a game is running).
Retroarch cores and stock emulation are based on the same emulation, so there shouldnt be differences of that magnitude in emulation.
What you are experiencing isn't a common issue.
I'm running PAL FF8 with FORCE NTSC, and 85% CPU clock (which would break the frame limiter, if I didn't use force NTSC), and the result is a faster running game (than the original PAL version), with little to no audio distortion (I don't hear it) - so in my book thats a positive. In games like Legend of Dragoon, when setting the PAL version to NTSC, audio distortion is clearly there - and again, the game runs 'too fast'. Try forcing PAL in that circumstance.
Also - in Retroarch (Autobleem), there are several PCSXRearmed cores, but then - if you started with the extreme coreset - it will have populated settings - which other cores will use as well. You could load up one of the more 'stock' ones, and then use the start button in core options, while a game is running, while highlighting every option individually - to reset that option to that cores default. Just so you see, what settings changed between KDFMManiac 'extreme' version of that core, and a more stock one. Should mostly be emulated CPU speed, but maybe there are others.
Also try disabling vsync (Video Options) to see if it is related to your issues.
None of the potential causes should require you to switch to the stock emualtion core permanently (although thats not necessarily bad either..
) is what I'm saying. Get to know core options, and what they are doing.
