Elden Ring is too slow

This game is primarily CPU bounded but it's in a weird way. The GXWorker threads spin a decent amount of time in a forward_list. The primary thread also walks these lists. They seemingly pingpong work and never achieve 100% core utilization. The Primary thread is typically around 80-90% loaded, while the GXWorker threads are 15-40% loaded depending on platform.

It really just smells funny.
