A speedrunner with the handle "Shizzal" recently broke Portal's four major speedrunning world records, becoming the current top runner in each major category.

The most prestigious Portal speedrunning categories, as indicated by Speedrun.com, are Out Of Bounds, Inbounds, Glitchless, and Inbounds NO SLA ("Save Load Abuse," a Reddit poster clarified) are four.

Shizzal is already the world record holder in the first three, with his fastest times in the Out Of Bounds category at 6m, 53s, and 940ms; the gap to second place is only 120 ms, illustrating how tight the intervals between perfect runs are.

Yesterday, Sisal's In Bounds No SLA record was recaptured by another runner, Adamantite. The current world record is 12:01:750 ms, but Sisal asserts in his YouTube video description that "sub-12 is possible."

"It's probably my main goal for a while. I can definitely improve on this run, minus the door-running."

"I'm not sure I'll be able to do that, but I'm sure I'll be able to improve.

The Portal speedrunning scene has been booming of late, with the top four runners in the Inbounds No SLA category all setting records within the last month, and Shizzal's two world records were set roughly a month ago.

There are a few outliers, such as a runner named Msushi who has been sitting in third place in Out of Bounds for over a year, but there is definitely a resurgence of interest in the scene as a whole, and if Shizzal is right and sub-12 is possible, Portal's newfound popularity will continue

Shizzal's video can be seen below. At any rate, it is worth checking out purely to see his reaction at the end." Carried away by doorlaunch!" he exclaims, his friends laughing behind him. I'm in love with what I see.
