Personally I obviously did notice the overhead with DOSBox when I tried DOS apps/games under HX, but the a few apps or games I tested on the desktop computer that I bought a few years ago worked least okay this way. Not that many of them will run near as fast as in a native DOS when using on a modern PC, but at least at an acceptable speed in my testing. Some of them can in fact work pretty smoothly. To further speed up the applications under DOSBox, you may try to increase its CPU cycles etc. Moreover, Ruslan plans to write graphics hardware acceleration (OpenGL) for DOS based on the MESA project library. This will dramatically increase the rendering speed.
