I distinctly remember playing it with a buddy of mine in LAN in its first days. He had a 486DX4 at 100MHz, I think, and I a Pentium 75. He could play a lot of other games better, raw speed I guess, but he really struggled with Quake. It worked, but with a lot worse performance than on my Pentium.
I remember playing Red Alert on my 486 at the time. It was enjoyable game but something seemed a bit off.
About 3 months later I upgraded to a Pentium 200 and realizing that I'd been playing at 1/3rd speed because the 486 just couldn't handle it. Red Alert become much more fun after that.
