I guess you tried to reduce the quality settings to the minimum. Also, not setting the rolling speed to high can help a bit. Could you tell me what GPU you use ?
I have a NVIDIA GeForce GTX 1050 Ti using nouveau drivers. Though I might just give up on getting them to work well. In some cases they work far better than the NVIDIA drivers.
The 1050 should be working fine, Potential even in 4K if nothing else is running (an with a single screen config). I didn't test it with the nouveau drivers though, but with one of the latest nvidia drivers : 435.
