How To Disable UseUObjectArrayCache on a Palworld Modded Server

Note:

Setting UseUObjectArrayCache to false is one of the most effective ways to double your frame rates and stop the “loading freeze” that many players experience when returning to the title screen. While the cache is intended to speed up object access, in Palworld it often becomes a bottleneck that strains the CPU and causes significant stuttering. Turning it off allows the game to handle objects more predictably, leading to a much smoother experience on both the server and the client side.

1. Log In to Your Panel
