Most Dynamic FPS problems are easiest to solve by checking the compatibility chain from the bottom up: Minecraft version, loader, mod build, dependencies, then interactions with the rest of the instance.
Crash immediately after adding the mod
A launch crash commonly points to a version or loader mismatch, a missing dependency, or an incompatible combination with another mod. Confirm the exact file you added before changing unrelated settings.
Missing configuration screen
The mod can be installed even when the menu you expected is absent. Some setups rely on optional configuration components such as Mod Menu or Cloth Config to expose an in-game interface.
Background FPS still looks unusual
Dynamic FPS can maintain a responsive internal loop while cancelling superfluous rendered frames. A single FPS counter can therefore be a poor measure of how much rendering work is actually being avoided.
Conflict with another performance mod
Temporarily disable recently added rendering or optimization mods, keep only required dependencies and Dynamic FPS, then re-enable components one at a time.
Quick check
- Confirm the Minecraft version.
- Confirm the loader family.
- Confirm required dependencies.
- Test with a minimal mod set if behavior is unclear.
Settings seem to reset after an update
Major revisions can change configuration formats or option sets. Review release notes and treat a changed default as a possibility rather than assuming the update failed.
A clean diagnostic process
Create a test instance with the same Minecraft version and loader, install only the required dependencies plus Dynamic FPS, and confirm baseline behavior before copying the solution back to the main modpack.
