YouTuber VswitchZero was a little disappointed after getting his hands on a servicable old 486 DX66 and firing up Doom. Wearing the rose-tinted spectacles of PC gaming nostalgia, one might expect one of the fastest pre-Pentium systems to offer quick and slick Doom thrills, but VswitchZero lamented that Doom ran “very choppy, and [it was] not a lot of fun to play.” The issues were largely caused by the PC’s ISA bus graphics, so the YouTuber decided to work on a project to overclock the ISA bus to the max... resulting in a successful overclock of 212% recorded.
