This support article highlights some settings which can have a more pronounced effect on your framerate than you may anticipate. In addition to changing these in particular, it can help to focus on disabling the advanced settings.
We'll continue to optimize the game in future patches.
We'd recommend making the following changes to improve FPS;
- Disable the Advanced Grass setting.
- Set Grass Quality to Off.
- Turn off the in-game FPS overlay (default keybind: K). *
* Third-party applications which monitor FPS may result in less of a performance impact.
