Does Larger CPU L3 Caches help anything else on BeamNG?

I just wonder that larger L3 caches really helpful for BeamNG performing differently? I recently upgraded my CPU(Ryzen 5 2400G to 5600). Likewise, I noticed huge improvement on Ryzen 5 5600, and loading 6 cars faster as traffic cars and loading maps faster, and improve the FPS too.
