My system: CPU: I7-4790, Graphics: RTX 2070, 8GVRAM, Memory: 25G, OS W10 (64bit). X-plane version: 11.31.
Graphics driver Nvdia 418.91.
Maximum fps single monitor: 17-18 occassionally goes above 20 but never higher than 25., dropped significantly as two additional monitors are added (in the range of 7-8.. Checking the GPU utilization via task manager, only about 10%.
I looked at and followed the video by Q8Pilot, but to no avail.
I have downloaded and reinstalled clean versions, again no change.
I hope some of you more experienced x-planers will have some ideas.
