Hey! A few random fixes that might help:
- Swap to Borderless Windows if you haven't already
- Update to latest NVIDIA drivers (419.35)
- Turn off background software that might be hogging resources
- Turn off Vsync if you are running a GSync monitor
- Change from DX11 to 12 or vice versa
If neither of these works, please contact support and they will help you troubleshoot further, as well as get your information to our devs. Thanks!
