I don't know if it'll work for yours but hey why not give it a try..
In the detail settings, try lowering the texture detail to say medium. keep the other settings to a medium or low setting but can make players and benches maximum.
When I've tried it in mine. Loading only took a few seconds. If you still see a little slowdown, try lowering the players and benches a bit. Hope this works for you all...
Tell me if it does...
