A free mod for Valheim, by TheSxW.
ValheimFPSBoost Custom is a mod that can be applied to your game, allowing you to increase the FPS by setting some variables and by creating different custom shaders. It can also increase the performance of the game.
It allows you to adjust some settings, including the number of particles, the number of lighting sources, the number of light frames, and the quality of the textures. It also allows you to set the LOD bias, the maximum LOD level, the maximum number of frames queued up by the graphics driver, the pixel light count, the realtime reflection probes, and the shadow resolution.
