You have to realize that DOSBox is not multi-threaded. So more cores will not help. What does help is a higher GHz rating, or just generally a newer CPU.

DOSBox has no OSD functionality. But cycles are normally shown in the window title bar (assuming windowed mode).

This is not the place for asking questions about DOSBox forks. There is a dedicated DOSBox-X thread you can use to post questions in. This thread will likely get locked soon. In any case "OpenGL Pixel Perfect" is unfortunately a bit of a misnomer. It is not perfect. See this issue about problems …

set a fixed cycle count, instead of the default 'max', which will vary if the game runs in the background or foreground.

These files seems to be meant for the Orchid ProDesigner ET3000 card, but presumably will work on any ET3000. Unfortunately it seems disk1 is missing from the ZIP file. Not sure either what it would have contained. And these are not actual disk copies, but only the files with the original timestamps …

the emulated FPU in DOSBox cannot pass the Intel MCP test program, so I would not use it for anything important. Neither can native machines past Pentium 2, due to changes in the floating point unit's accuracy. It doesn't mean they are less accurate, they simply don't give the exact results that …

Also CAD programs tend to use the floating point unit (FPU, x87, MCP). And the emulated FPU in DOSBox cannot pass the Intel MCP test program, so I would not use it for anything important.

I created today a Pentium MMX class machine in 86Box 3.11, and gave it a 2GB RAW HDD image with Win98SE pre-installed that had been created with DOSBox-X. On first launch, it obviously found tons of new hardware, but it worked just fine. In fact, on my system, the guest OS felt a lot smoother in …

The IBM PC Server 704 was a quad-socket PentiumPro server with PCI and EISA. I remember the box from back in the day.

Not with standard DOSBox. As mentioned, once you 'boot' a guest OS image, you loose access not only to any folder mounts, but also to CD-ROM drives, even when mounted via IMGMOUNT. The later is because standard DOSBox has no support for IDE emulation, which is needed to load a DOS CD-ROM driver.

As for 86box specifically, it looks like it hasn't gotten an update for a few years, so if it doesn't work there's not much you can do, unless you want to try the nightly version and see if there's been a fix. Are you mixing up 86Box with PCem? 86Box has regular releases, the last one being from …
