Valheim Optimization: Boost FPS on Massive Builds | PUP FPS Mod

For the best performance, restart the game after baking a large base. This clears temporary baking data and loads the base directly from the optimized cache, which can provide an additional FPS improvement.

PUP FPS is a performance optimization mod for massive Valheim builds. It combines thousands of repeated building pieces into optimized clusters, reducing the load created by extremely large bases.

The mod is most effective on structures containing many repeated Grausten, wood, stone, black marble and other supported building pieces.

During our tests, performance on large bases improved from approximately 40–80 FPS to 100–200 FPS. Results depend on your hardware, graphics settings and base complexity. (rtx4070 super +r9 7900x)
# Performance Tips

For the best performance, restart the game after baking a large base.

Restarting clears temporary baking data and loads the base directly from the optimized cache. This may provide an additional FPS improvement, especially on very large bases.
