FS-UAE uses always maximum CPU speed?
Hi,
I have FS-UAE installed under ubuntu linux. When I start it, all is ok. But when I do something at the emulated Amiga-side, e.g. assembling my app, then my CPU fan goes to maximum. Is there a chance to make this not happen? Indeed NO other program has this effect. Even E-UAE does not do this even when in jit-mode. greez Andreas |

You can limit cpu speed in fastest possible modes. For example
Code:
uae_cpu_throttle = -250.0 Perhaps you should also take a look at vsync options. Turn it on/off or try a different sync method... |

Oh dear, with that throttle everything takes ages, even when I use -50 or -300. I was not able to figure out which direction is faster/slower.
Here ar my settings regarding the ones you mentioned. Code:
accuracy = -1 input_grab = 0 video_sync=off |

BTW: Did you check your graphics card driver? Perhaps your opengl display is rendered in software mode... |

So if you're emulating A500/A600/A1200, by default, FS-UAE should only use as much CPU as needed, not more. (There's some exceptions here, in vsync mode, with some driver/OS/sync combinations, the GL driver might busy-wait for vblank, but with video sync turned off, this shouldn't be an issue either). So please post your FS-UAE.log.txt. |

The log shows that you are using the A4000/040 model, which is meant to run as fast as possible.
However, you may want to try the latest development version instead. That series has some changes regarding how fastest-possible-mode works, and also, there are some other throttling options available if needed! So please try the latest development version and report back if it works better for you or not |
