Not require, just recommends Pentium 60 minimum. Like Quake Tomb Raider loves pipelined FPU, 30 fps on Pentium 60 vs 15 fps on 486DX2@66 and 20 on DX4@100.

Whoa, you took me back quite a few years there!
I really wanted a DX4@100 back then but it wasn't available in my area. I "had" to get a Pentium 60, which I was not happy about lol.
Upgraded to a Pentium 200 MMX. Whoa!
And then I also got a specific batch Celeron 300a to overclock.
"Stole" my dad's Matrox Mystique, coz what does he need a "3D" card for? Played "Destruction Derby" a lot, just coz 3D card: https://archive.org/details/dd2matrox_19961205
Wow, the times!
If I remember correctly the Pentium 60 was the one that had math rounding errors, isn't it? What a memory
This?
https://en.wikipedia.org/wiki/Pentium_FDIV_bug
> The FDIV bug affects the 60 and 66 MHz Pentium P5 800 in stepping levels prior to D1, and the 75, 90, and 100 MHz Pentium P54C 600 in steppings prior to B5. The 120 MHz P54C and P54CQS CPUs are unaffected.
Iirc the only way of getting near 30fps on a socket 3 board is by bumping the bus to 50mhz, having fast cache and a 5x86 and enabling branch prediction and the fpu optimisations. And then wait for it to fault out. Never tried it with an Pentium overdrive though, maybe that will work but those do not like higher bus speeds. Might also be a nice difference in DX4s since the amd and cyrix parts have different fpu implementations to the intel ones.
