Dosbox android change cpu speed12/28/2023 Keep in mind that emulation is different than running code natively. Cycles=max will run everything as fast as possible on your cpu, with no fixed value. There’s no 1:1 value that relates to a certain cpu type, but these are some rough estimates: There are different cpu tyoes DOSBox can emulate, but the default 80386/486 cpu is fine.Ĭycles: the amount of cpu operations executed. Tie Fighter was designed for fast 386 or 486 cpus back in the day, so you should use these settings under Ĭputype=auto: leave it as it is. I’d suggest you try fixed cycles, and see what happens. You can try to work around that with root and certain cpu tweaking apps, but that’s certainly not a valid suggestion, as it involves tampering with your phone’s brain. Happened to me in the past as well, and that caused massive slowdowns. What might be happening is that your phone’s power management loads the Dosbox process off onto one of the power saving cores of the cpu. Mgc?Įxpert settings are identical to what you do on PC. Do these overwrite it? Or are these yet another setting inside the. I guess some of the things I am confused about is why the settings here are different than the way I have it set in. Sbtype=sb2 (why is this set at sb2 when in the. #Amount of video memory in kilobytes, in addition to vmemsizeįrameskip=2 (if I set this to 0, every frame is being rendered so therefore slower performance right?)Ĭore=dynamic (what offers the best performance? Or should I leave it as is?)Ĭycles=3000 (is this where I change to 120%? Or do I plug in a higher number than 4000?) #vmemsize=2 (2 mb is the default video memory? Is this referring to its own standalone video ram on a video card, or shared with the 16 mb? Increasing it to 8 mb should give me more performance?) # The maximum resolution and color depth the svga_s3 will be able to display #Amount of video memory in megabytes (0-8). Machine=svga_s3 (from what I gathered, svga_s3 is the best in terms for performance out of all the other pc dosbox can emulate?) Can you guys help me understand these? I’ll put a parenthesis () next to questions I have: I have never fiddled around with expert settings before, and the guides I have seen online seem to be for the pc version and I am not sure if they share the same directions with magic dosbox. I recently reformatted the phone, didn’t help, and restarting the phone doesn’t help either. Whenever I get close to a battle with a lot of shooting and objects it slows down, it wasn’t like this when I originally got the phone. There is some details on my commit to fix the aforementioned bug on how this is mapped to ScummVM and the remaining inaccuracy due to differences in implementation.It’s for TIE Fighter. And knowing how this interrupt call works, we can replicate the same behaviour in ScummVM. In this case we could see that the original executable is using the 1Ah interrupt to control the speed of the animations. We have access to the original source code for this game, which helps to check the behaviour of the original executable (no reverse engineering needed!). We actually had a bug report about the speed being wrong when compared to DosBOX ( bug #7115: DRASCULA: FPS are incorrect or some frames are dropped). But in that case as well, we aim at reimplementing it in the same way as the original game did it (either based on the original source code if we have it, or based on reverse engineering of the original executable).ĭrascula is one example of an engine using hardcoded animation speed. Or for some other games the speed is hardcoded directly in the game engine and not controlled by the game scripts.
