It takes 12 miliseconds to blit from memory to screen 640x480x15 bitmap!!!! I count with simply counter which increments variable time_count every milisecond. Here are some informations about what I use: - DOS 7.10 (not prompt from Win95 - real DOS) with 4DOS6.01A - video card ET6000 with 2MB, VESA 2.0 supported - QEMM v9.0, without Quarterdeck's QDPMI - UniVBE 6.0, becase my monitor is old (January, 1992) - here I got VESA3.0 and it says VBEAF (this should be software emulation, or what?) - DJGPP 2.03, Allegro 3.12 Does anybody know what could be problem (maybe someone knows what IS problem), or this is one of those questions: "My program doesn't work. Guess what's wrong!" Alexa
