When I run the cross-compiled game in DOSbox, it is really slow and slow.. Some "cross-compiled game" may require beyond emulation speed possible on your computer. In case for that game are known requirements of real hardware, you may evaluate your computer's emulation performance limits as it's …

I still to this day experience issues with various systems and power management screwing things up. It's been a pain since it started and it looks like issues will never end.

MrEWhite The important is the comparision between CPUs, so this needs to use the same test - 0.74 (32 bit)

I can't hear any discernable difference between NukedOPL and real hardware, fwiw. This may depend on a concrete music or sounds. What is your sound hardware and its system settings. Not only software's settings. Should be used blind comparision, anyway, and there are such plugins for music players. …

The first pass has to translate the code then run it, subsequent runs don't need to translate if the memory hasn't been changed. Speedtest by 2 runs (2 identical strings in a batch file) by the recommended procedure gives results differing <5% on my machine/OS and 0.74. This % is similar to random …

With dosbox 0.74-3 I have 1124.7 instead of 803.4 with the first pass. Why these differences ? It's better to try a real game as Doom or Quake and in case you'll get significant (>10%) instable benchmark results there, - to ask about strange emulation behavior in a specific theme or development …

in case there is a good reason why 64 bit versions of DOSBox aren't more prevalent They are expected to coexist with x32. The best would be place x32 and x64 SVN builds together alike dosbox-x does. And maybe to place a note about more possible issues of x64 build with the recommendation to try x32 …

some data is there DOSBox 0.74 CPU Benchmark https://www.dosbox.com/wiki/Performance It's an approximation which supposes a similar enough code. Doom and Speedtst performance should be useful for most games. Quake is more useful for late 3D games.

Seems the next significant improvement should be x64 code of dynamic core for x64 build. It exists in current SVN and improves the speed a lot.

Would be interesting to see the sound comparision of this with standard DOSBox's FM emulation. Better in some games to notice the practical imrovement. It's not clear when the significant difference can be noticed.

Star Control 2 is one of the games having excellent music and GUS support. I had no correct work of GUS emulation there with 0.74, at least. I hope there will be guide to fix that sometimes. There were only about ~300 games with GUS support.
