massive fps drops

Hey

My Setup : Ryzen 5600x RX 6600xt 6GB ( ordered an rx 6750 12gb today becauze of the +40% performance for wqhd in benchmarks ) and 32GB Vengeance 3600mhz RAM.

When I play in the open world I have a constant 100-120 fps. When I go into battle it always drops to 45-55. I play witch minion build. I play on 2560x1440 WQHD but when I set it to 1920x1080 it's no better. I've already set everything to low, dynamic culling on, dx 11, vulkan, everything... nothing helps.

same situation, I really don't know what to do...
