What does the CPU usage look like when real-time is running? Is there an increase/jump in cpu usage when you move your mouse across the screen?
Are you running your monitors off the integrated GPU or do you have a dedicated GPU?
If you have time and the ability, I would be interested if it helps to run just a single monitor setup with a ~1080p resolution. I’m ultimately curious if it is related to your specific video setup. I can’t reproduce any issues here on a i7-6700 running 2 1080p displays.
Do you have any anti-virus software running other than windows defender? If you have any other heavyweight software running it might be interesting to see if closing it out helps any. This might be a long shot, but setting the PC to the high performance power plan might help, go to the “power options” menu in the control panel and set your power plan to “high performance”.
