Which OS are you on? What graphics card do you have?

I'm using Windows XP home edition with a ATI 3D rage IIC AGP video card.

I might also want to add that the lag only happens when i full screen
dosbox. When it is windowed, the problems do not occur.

"ATI 3D rage IIC AGP video card"

Use a video card made in the current century please.

Hmmm... Have you tried going to your ATI display control panel and change the settings to 32 bits colours (a.k.a. "millions of colurs")?

You can also try different output-methods in DOSBox. E.g. overlay instead of surface, ddraw, opengl or some other mode.

Hehehe, thanks for making my morning, DosFreak (;

I would advise running that ancient card with 16bpp. How much video RAM does it have? I guess no more than 4MB.

Thats what im trying to do - get someone to explain how to down the bpp to 16.

yes i have, the "24 bpp" message dissapeared, but the lag remains.

i'am not shure if the rage 3d and color depth is really the problem in your case.
if the rest of your system is also from the same century like the graphic card, you're better off playing it under real dos... 😉

Wolfenstein 3D runs fine at the standard 3,000 cycles here. If that is too slow in your computer, you may consider using frameskp rather than increasing cycles.

Try changing output mode to something that isn't surface, like try overlay (Rage II has good support for that). The card is too old for OpenGL though so forget about using those.
This is an SDL issue
