I've read all the topic here about why cycles defaults to 3000 (real mode), but I don't see any way to change that AND still have the auto function still work.

If I set the initial cycles in the config file, it will no longer automatically bump up when playing a DOS Extended game like Doom. Can that 3000 be changed?

3000 is way too low for a lot of stuff. Equates to maybe a slow 386 or something.

With modern computers you can just set it to 30000 or something and forget about it.

I flermmed the plootash just like you asked.

If something needs 30000, it's likely a protected mode game and can bear the max speed that auto throws on. There's also some recent platforms that can't handle 30000, such as a Pi3B.

3000's a fine.default.

Hi! I was going to say that, too.
Back in the 2000s, when DOSBox was young, 3000 cycles marked the upper end to what was possible with the average PC.

On my old PC of that time, going up a bit to 9000 cycles was enough to
distort Sound Blaster emulation in Windows 3.1, for example.
With 3000 to 5000 cycles, everything was smooth, albeit a bit leisurely. ^^

Edit : Also, if memory serves, DOSBox was originally intended to provide a 386/486 level of emulation.
So performance wise, a 386SX16 to 486SX25 range wouldn't have been too off, I assume.
For a standard configuration, I mean. That performance was safe for old games like Lemmings or Wing Commander, still.
