Perhaps. No on-die floating point, though.

Doom uses fixed-point arithmetic[1], so no problem.

At the time of Doom's release many or most DOS/Windows PCs still didn't have hardware FPUs https://www.xtof.info/blog/?p=931 I think that using hardware floating-point would have prevented some of the early console releases too (particularly the SNES?)

The SNES version was coded from scratch in 65816/Super FX assembly language [1]; how the PC version did things would’ve been neither here nor there.

Doom doesn't use floating point.
