I don't think it would know the difference!!

Bleh. Try another tool like NSSI, perhaps? it helps more?

It could be an IRQ conflict, dunno.

IIRC, Quake "almost" runs perfect, though the sound breaks up
sometimes. Yeah, DOSBox = "fast 486" while Quake really needs a
Pentium (FPU).

You could try "core=dynamic", but that may? need to be directly
tweaked in the config file (only). Also, of course, make sure
"memsize=64" (also in config file only) so it doesn't swap to death.
(Hexen2: HoT doesn't even seem to load in default memsize=16. And yes
that gets choppy too, no surprise, it's Quake-based.)

Then say goodbye to sound!   :-(

Really? That's odd. DOSEMU should run Quake at native speed, even
under x86-64! (Yes, I've tried!) No idea why that is, but try "dpmi -m
0xA000" to see if that helps (doubt it, but ...). Seriously, something
is up if it runs *slower* than DOSBox!!

I guess you mean the menu items in CONFIG.SYS (etc).


That file includes "docs/config.txt" (lists various CONFIG.SYS
settings, including "menu").
