Prior versions often overloaded a single core while leaving others idle, creating a bottleneck. The 1.580.0 executable introduces an exclusive CPU affinity mask that dynamically balances draw calls and physics calculations across physical cores, avoiding the pitfalls of simultaneous multithreading (SMT) where performance can regress.

This specific update tier is called "exclusive" because it introduces custom PC options not found on consoles. These features leverage specialized hardware from NVIDIA, AMD, and Intel. Key Performance Upgrades and Graphical Changes
