![]() It seems to me that unless you have a very old computer, then other parameters than the processor do not matter much. In this case, even if you buy one of the more powerful processors, it may not help much if its power will not be used in case DOSBox uses a single core. By the way, as you've noticed, it's very possible that DOSBox uses a single core. However, just because you buy a new processor does not guarantee that the game will not stutter. Running "newer games" already released for Windows 9x may actually require much more computing power. I know that many old games may no longer work on Windows 10, 11 (many times it happened to me that games that did not work on Windows worked without problems on Linux with Wine). These settings are sufficient for most games released for DOS.ĭon't you have an x86 PC that you want to run post-DOS era games in DOSBox? If you're on an x86 machine and want to play Windows 9x games, it's best to run them directly in Windows. If the game is too slow, very often it is enough to set: cpu=dynamic Setting too many cycles to hard can cause the game to run even slower. I know, not technically a DOS game per se since it was in the era of Win98, but there weren't that many 3D games prior to 1995. ![]() I tried setting to 407000 to approximate a Pentium III machine, but this actually makes it even slower to the point of being unplayable, which I can only surmise is because my CPU can't actually handle that many cycles.Īn example of a DOS game that doesn't run well would be Tzar - Burden of the Crown. On auto, as mentioned, there is significant lag with 3dfx games. ![]() I actually played around with cycles=auto, and cycles=407000. I would consider upgrading to a SSD but they are still pretty expensive at the higher capacities (I store a lot of my video files on them as well for my work so I do need higher capacity than is affordable for SSD). Similarly, I suspect that my GPU wouldn't be the cause of any bottlenecks? It's a pretty fast GPU (RTX3080ti) but the only thing I can think of is driver incompatibility with older DOS programs, so they can't actually tap into the GPU power, but short of installing a Voodoo graphics card, I can't see there is anything to be done here.įinally, I know that the hard drive is probably the other obvious culprit since I store my DOSBox root folder on an external 7200rpm SATA rotational drive. My PC already has a ton of memory which I use for my video processing work so I don't think that is the issue and I think upgrading RAM speed might not be as useful in this case? Right now, I am thinking either of upgrading my CPU to the 13th generation processor, but since multi-core is less important, does that mean that Intel is a better choice than AMD for processor since Intel tends to have higher overall single-core clock speeds? Also, does that mean that i9 processing power is wasted if multi-cores are not being used and that sticking with an i7 (or even an i5) is good enough? I know modern games cache themselves into RAM and thus hard drive access times become less important, but back in the day, was this a far more important factor? The other thing that I am wondering is if the performance issues might actually be due to hard drive speed. GPU performance is less important, and RAM speed and quantity is not as important. From what I read, it is mainly processing power that matters, and to focus on single-core processing power. I want to upgrade my PC but not sure what to prioritize. (this can be changed in the DOSBox configuration file).My DOSBox works well for 2D games but lags quite badly on 3D games.
