OptiArk Features

Performant Gameplay

Performant Gameplay

Experience high framerates on even weaker hardware. About 300-1000FPS depending on settings, but we do have some good premade settings that are the bare minimum to make your gameplay the smoothest it can be.

Runs Great on Various Hardware

Runs Great Everywhere

OptiArk is created for efficiency and framerate. It runs pretty great on a wide spectrum of hardware (that can run java 21+), delivering high framerates and some qol mods without demanding top-tier specs. (image is a 680m integrated laptop gpu running the game quite well)
