Basically, better framerate and such, nothing to do with enabling bunnyhopping or anything actually gameplay related.

Regardless, I thought it'd be something like that, just wanted to be sure. Thank you!

Is using the standard OpenJK client (i.e. no additional mods) allowed for the main categories like Any% and All Levels? It's supposed to work exactly like the original client, just with upgrades that don't affect gameplay. Does this hold true? I ask mainly because I have tend to have better luck with OpenJK's performance.
