Max Settings and it works flawless on both my machines

1. Ryzen 7800X3D X670E-E GF4080S, 64GB
2. i7 6850K X99 GF1080ti, 64GB ( lesser FPS but quite above the 70-85+ FPS range )

As with most MMOs in crowded places the server can't handle the best load to all and downs you a bit, but not feeling it to the level you describe on either machine...

If running windowed mode, you could try and go Fullscreen. with the new DLSS and FSR Setting you can try and set it to run at max FPS all the time,,,


Function is in System Config - Resolution - Frame Rate Treshold - set to always enabled.
