Use Dx12 for better performance!!! It will stutter when u load onto a new map for the first time because it will be compiling up all the shaders.. So as you go everywhere on a map, the compiling will be complete and stutters will disappear.

Some times Dx12 wont work out but i suggest you give it a chance..Dx12 also reduces the burden on the cpu.

You can also play on Dx11 if you're ok with that but make sure you turn on *Future frame rendering* or gpu usage will be low.!

*Tips to reduce cpu usage:
1. Set Lighting quality to low
2. Ambient occlusion to SSAO or off
3.Disable steam/origin overlay

There could be other settings which might help with it but im not sure.

Thanks!
