If I had to guess on why DOSBox is faster than DOS on the same machine I would guess that the DOSBox knows more about the graphics system than DOS does and can emulate the video better than DOS can utilize the native graphics hardware ... I would guess that the graphics card in the machine would make a lot of difference. Read my messga Windowsi Patterns Speedtest qte Cycles=fixed 205170 core=dynamic The Patterns image that yesterday in the "cycles=max" setting needed about 14 minutes, is now finished in 2 minutes 15 seconds, unqte the default mandel needs 7 seconds at 1280/1024 The cycles value has been found during calculation and watching the CPU performance on the sidebar cpu meter. If core is set to dynamic 2 cores are used above a certain speed. The XP dos is still much faster the Patterns image is generated between 65 and 90 seconds, pending other processes ; Petta
