Beam NG Fps Drops

So I've been playing beam NG since 2017 and ever since I've gotten a new Pc for Christmas beam NG has been having so much Fps drops there's nothing i could do. The new Pc i have has a NVDIA GeForce RTX 2018 Ti in it and it can barley run Beam NG with out the Fps dropping from 120 to 50 for not even a second and it ruins the game for me. also if i even spawn in 2 cars the Fps drops like crazy.

If anyone can help me please reply
