hello, i recently got arma reforger and i barely get 50 fps and drops to 17 fps

I dont know whats going on but i bought arma reforger hoping for a more optimized gameplay rather than arma 3, looks like arma 3 is more optimizated than arma reforger i get 59, 60 fps at arma 3 and in reforger i get alot of fps drops even on servers without mods i get like 40 and fps drops, any help?

My setup

Rx5600 xt 16ram i5 10400f
