Well, it doesn't make any performance difference between the two versions anyway ?And by the way, in SVN-Daum version, you can just "maximize" it while keeping it windowed, not full screen, since I have 2 monitors here on my main computer, that makes a huge difference for me, since there's no "borderless" option ?
Play in window, not fullscreen for testing.What are your CPU, MB, video card and OS?DOSBox regulates internal speed depending on system's performance. If CPU's speed jumps, then this may result in lugging. Thus may be tried something.Try to remove background processes like antivirus, net connections, etc.Check is CPU officially supported by MB, BIOS is newest and chipset driver is fresh. Try to disable energy saving for CPU in BIOS. Disable hyper-threading. Set higher allowed TDP limits and lower CPU clock.Assign to DB higher priority= in config. If it's possible assign DB to run strictly on single core.Try to disable sound in game's settings to exclude IRQ sharing issue. 2b1af7f3a8
