E-UAE on Amithlon with 1,4Ghz to slow ?!
Hi there,
i built an amithlon system from scratch these days, got network and sound working and seems stable so far. I downloaded e-uae for 68k (hard to find on the internet, isn't it ?!) and played around with it yesterday. Well, it's much slower than i expected. Used 68000, 512KBChip, Frameskip >1 and just wanted to play Hybris nothing special I guess.. but, it lags and the sound skips and hicks.. 1,4Ghz Athlon CPU is to slow !? I see poeple emulating 68040 with Workbench and RTG-Screens, what supercomputers are they using ?! Is it because the JIT cannot be enabled on 68k-Systems (what amithlon emulates, underneath it is x86, you know that.. o) Any hints for me !? Have a nice weekend, tbone.. |

I'm no expert on Amithlon, but it sounds like you are doing emulation inside emulation. So therefore you require double the CPU power (or more) to get a decent result.
WinUAE just about gets by on a 800Mhz CPU minimum in native Windows without JIT, the recommended suggestion is 1Ghz, so a 68K E-UAE version inside an emulated Amiga environment like Amithlon sounds like it's going to need a CPU faster than 1.4Ghz for decent performance. I'm not familiar with E-UAE, but check it doesn't have any options like "cycle exact" or other performance sucking compatibility options enabled. To me though, it sounds like you need a better CPU. |
