DOSBox will most definitely not break your CPU...infact even if it wanted to it couldn't 😁. So feel free to test as much as you like. You have probably misread the readme - increasing the cycles will only help until the point where you CPU is working at it's maximum. After that the speed will not increase anymore. I'd recommend somewhere around 15.000 to 20.000 cycles for Doom2.

bad for emulation, not bad for your CPU 😉

hehe ok thx :]

Oh... Developers did not think that anybody will take that "bad" so seriously....

"Bad" here means that if you use 1000000 cycles DOSBOX will not be quick as a cheetah, but slow as dying snail, because there is no computer in existence which could handle such speed... Nothing more....

There is not any known way how DOSBOX could destroy your computer, so you can experiment as you want. 😀

I think a good setting for you as i set up DOSBox for a PC with somewhat similar alibities would be 18000 emulated cycles and 2 for frameskip. Frameskip will not really hurt as it skips from 70Hz (in 320x200, 256 colors), so by setting it to 2 you will get at around 23FPS which is enough. Troubles might rise if the game uses the 18,2 HZ clock for updating since then this two rates really interfere causing jerky motion (This is more true at 60Hz modes like 640x480 or 320x240 where you would get 20FPS). Then set it to 1 resulting in 35FPS what will "filter" the interference out better (but will ask more from the CPU).

You're probably better off with a Doom source port anyway. There are plenty around for windows and probably a few for other O/Ses as well. A source port will run much faster/smoother than emulating the original dos version of Doom, and many source ports offer optional enhancements like high resolution graphics as well. Doom Legacy and Doomsday are probably two of the most popular ones for Windows.

Lofty, both are available for Linux as well. As fas as I can see, Doomsday focuses more on good appearance (that's why I use it) while DL provides lots of features for level designers.
