When did floating point performance become irrelevant?

ZDoom LE, Pentium 133's, Windows 98, and DOS 3.1 all go here! A bygone era, of particular interest to some folks.

Someone said that with vanilla, amd cpus (486-k62) would give better performance than intel due to their floating point performance. Was this only for vanilla? And if not, what cpu's started making it irrelevant?

It has mostly become irrelevant when the math coprocessors became standard equipment. Doom has been written right at the time when this wasn't the case. A first generation Pentium would have been more than suifficient to run a floating point version of the Doom engine.

Of course back then fixed point was indeed faster, but not by factors which would have made it a problem.
