Like many things its a balance of both. At high thread counts the game is still performance bound by the main thread, this is what people mean when they cry single threaded. Saying the game is single threaded is technically false, but having faster cores is going to make the most noticeable difference once you're dealing with modern thread counts higher than 8.
An interesting experiment would be to benchmark the game with half of the cores disabled at full clock against the same CPU with all cores enabled at half clock. Which do you think is faster on a 5600x for example?
