NewJK is our optional improved custom executable that replaces jamp.exe, which launches when you start JKA. It can improve FPS, has many crash fixes and stability improvements, and adds extra capabilities like raw mouse input. While NewJK is not required to use Newmod, we highly recommend it.

Newmod users should only use the vanilla executable or NewJK. Other projects (OpenJK, EternalJK, JAMME, etc.) are not recommended for use with Newmod.

Non-Newmod users are fully encouraged to use NewJK. Newmod and NewJK are independent projects; neither requires the other. The benefits of NewJK can be enjoyed on any client mod, not just Newmod.


NewJK can be downloaded from the download page.
