If you look both M+KvsController in some records, you will notice that m+K is far superior than a controller. That's why the leaderboards are separated.

Sadly there is no speedmeter on Quake Remastered, and there was one used to be on Livesplit but after some updates the speedmeter stopped working.

About the 100m map still working though I don't know... I recommend you join the discord sv!

Is it allowed the use of Saves and Loads speedrunning this game?
