DosBox incredibly slow only when drawing 3d

I have tried several games, all with the same results, which leads me to believe that it's not a problem with the specific games.

The problem is, whenever something 3d is being drawn, I get terrible framerates, yet the moment it stops, everything is fine. I have tried a wide variety of cpu cycle settings, and while it helps a little, there is still a noticable difference whenever something 3d is being drawn.

Example: In Daggerfall, everything runs like a dream, even the live action sequence before you begin the game. The moment you are plopped into the game, however, everything is amazingly slow. If I were to press escape, or open a menu, everything would be fine, but the moment I get back into the game everything slows down majorly again.

Other games tested include Magic Carpet (which ran slow only when actually playing in 3d), and Dominus (which didn't run slow at all, due to it being a solely 2d game).

Any suggestions?

Get a faster CPU and increase the cycles? Daggerfall runs fairly smooth at 20,000 cycles.

Thing is, the same thing would happen if you played Daggerfall on a slow 20-33mhz computer. Menus fine since they hardly pushes the hardware, but slow during the actual gaming part.

This is only a problem with DOSBox 0.63, apparently most 3D games run fine in 0.62, but unfortunately for us, they've taken the WIN32 download link off their site ><

That is not true. DOSBOX 0.63 certainly is not slower (usually quite the opposite - because you can increase its priority by a setting in DOSBOX.CONF). But remember that configuration settings change between versions. So use new config. Experiment with options. Read guides about running resource demanding games in DOSBOX Guides or WIKI (settings in DOSBOX.CONF can have *BIG* influence on performance).

Old versions are still for download on sourceforge page of DOSBOX. But if you want the older version just because it is supposedly much quicker, then I do not see any sense in that (it is not quicker as I explained above).

I had this issue with Magic Carpet.

I unplugged my analog Joystick, and wa'lah, all fixied. 😉

Seems the analog joystick does something odd to Dosbox, be it active or neigh. I can't remember where I read this though.

Granted, I've other Magic Carpet issues, besides speed, but tis not hte place for it.

This is known issue. Do not use any analog joystick with DOSBOX.
