I tried to run every test available, but not all of them were working, although I did find a few that performed nicely. ĭOS Benchmark offers CPU, GPU, and memory tests, as well as demo versions of the games Doom and Quake for benchmarking the environment.

However, I did find a test environment for performing different benchmarks under DOS called DOS Benchmark, which is available for download from. I remembered some benchmarking applications from back when DOS was popular, but they were hard to find. TestsĪfter performing a variety of tests, I discovered that it was actually hard to find some good benchmarks. I chose such a high number because of Quake, since at 32,000 cycles it gives the most fluid experience on both DOSBox versions. Some test programs reported it to be a 1285 MHz fast Pentium CPU. Pentium_slow is the CPU with the most features, and I set the cycles to 32,000, which is very high. There was no easy way to find the right settings, and after a period of experimentaiton, I ended up with the following results, with frameskip and aspect ratio turned off:ĭynamic cores should be used for any value of fixed cycles over 20,000. In contrast to games like “Duke Nukem 3D” ,which contains some 3D objects and use 2D sprites in many situations, Quake was already using 3D models, similar to the models used in later games on Windows, which was very impressive for that time. What’s remarkable about Quake is that the game itself is in 3D without requiring a graphical desktop environment.
While most games run fine with the basic settings, others only run with a very specific configuration, so I chose a set of values that worked best for the original version of the game Quake, since it’s very demanding on the hardware. ConfigurationĬonfiguring DOSBox can sometimes be difficult. The custom build of DOSBox for ARMv7 may be downloaded from my repository at.

I took some time to compare these versions and find out exactly what is improved by using an ARMv7-optimized build.īelow you will find a series of side-by-side tests that highlight the differences between the generic build of DOSBox, and a build that is specifically compiled for ARM. Some time ago, I compiled an ARMv7-optimized version of DOSBox which appeared to be running faster than the stock DOSBox version that comes with the official distribution. Despite its complexity and multiple layers, DOSBox runs surprisingly well on the ODROID platform. Since the ODROID uses a completely different architecture (ARM vs X86), it has even more work to do during emulation.

With DOSBox, you can replay your old games and play them on modern hardware, since there are many interesting and legendary DOS applications that aren’t available for Windows or Linux.ĭOSBox is very stressful on many computers, since you normally need a high-end PC to emulate a 486 at 33MHz.

For example, Shadowcaster is incompatible with it because RAVEN.EXE run with DOS/32A is unable to find the A32SBDG.DLL file that is in the same directory, while with DOS4GW it can.Ĭheck Dosbox' documentation to get further information as well as a guide on how to proceed.DOSBox is an x86 DOS Emulator that not only emulates the x86 architecture, but also emulates a common 1990s-era DOS environment. Note: not all games will work with DOS/32A. Once a game uses this, it is expected to run faster and better in DOSBox.
