What settings do you use? Especially sound settings and output method interest me, since I can't even get near 80.000 cycles on my 3700+.

I shall attach my config that I use take a look It's complete overkill for almost every other game, The standard DOS4GW.EXE will need to be replaced with the DOS32A so check out about that otherwise the game just runs even slower if at all. Also as I mentioned im not using the official build so It may just crash and burn if your using the official release.

Dont use this for your main config stick in the games directory or name it different otherwise you other games will be way to fast 😁

Good luck and could you post your results including any graphical errors which you should see on the second mission when the cars drive around.

80000 cycles 😳 😳 😳

3500+ MHZ 😳 😳 😳

(i know that this not really is a post, but when i read it, ist just SHOCKED ME !!!!!!!!)

I've just checked with a random game. I already knew that sound settings have an effect, but I didn't realize it would be _that_ much. Even when wasting CPU in many different ways, using heavy scaling options and frameskip of just 1, simply halving the audio data rates from 48000 to 24000 more than doubled my cycle capacity. That way, I get past 80.000 cycles easily.

is this still with the latest cvs as well ?
as I tried to optimize various small parts of dosbox (partly that ih8regs patch).

I'm always using CVS, though my build might be 2 weeks old currently. Since I use gcc's profile-guided optimization, ih8regs' patch won't probably do much for me. I don't like it either. This is what gcc says about optimizing branches by hand:

In general, you should prefer to use actual profile feedback for this (`-fprofile-arcs'), as programmers are notoriously bad at predicting how their programs actually perform.

Note that 80.000 cycles have not been the limit. Dosbox was still running at 100% real time at that point, I didn't take time to see how much further I could have gone - the only game I have that needs that much CPU power is unfortunately one that triggers dynamic core instability (Schleichfahrt). All others play very well with my usual 20.000-35.000 cycles (depending on program).

Oh, since I have time, I will go out now and do some benching, including latest CVS.

Can't tell you exactly what version im using the .exe is dated 25/01/2005 so I may try compiling a more upto date version in the next week and see how it goes.
