Hello palota,
The cU Mod is bases on S4ndmod, what is public, so they use mg42.
The thing is on s4ndmod the mod is lagging on bigger maps and if more bots are playing..
Only on rtcwpub, they dont even see it or use it. I think its a mod / engine related thing.
It includes the mod and engine in the same solution.
I would you include in the Github, where i got my actualy work on rtcwpub. Maybe you can have a look on it whats wrong
Il invited you in my Github Project
Cheers Beer
