How usefull is gzdoom for commercial projects?

Complete and accurate emulation of late 80s, early 90s PCs is still difficult to do at real-time speeds and low latency.

Well there's PCem: http://pcem-emulator.co.uk/

Isn't that severely performance-intensive? Interestingly, it looks like the download page has downloads for a couple freely-licensed BIOS dumps, which makes it seem like even that's not wholly complete and may need dumps of proprietary firmware to emulate certain hardware.

That's like calling MAME incomplete because it hosts a download of Gridlee.

It's only severely performance intensive when you're cranking up the Pentium MMX and enabling Voodoo2 SLI for at least 5 threads total. If your computer can handle the latest version of Gzdoom, then your computer can handle emulating a 20-year-old PC running a 10-year-old version of Gzdoom.

You're on your own for finding the copyrighted roms it supports. It doesn't do hacky HLE BIOSes. It's what you should expect when you're asking for "complete and accurate emulation of late 80s, early 90s PCs" (including requiring MFM hard drive controller roms for those older 80s computers)

On my Core2 Duo @2.4 i can emulate a 486 DX4-100 or a Pentium 66 at 100% speed. Of course you'd need to search for PCem v14 roms out there.
