Stuttering only when I have more than 1 monitor

I have this computer:

  • Intel Core i5-9600K CPU @ 3.70GHz
  • 16,0 GB RAM
  • 1 TB SSD Hard disk
  • NVidia GeForce RTX 3060Ti (updated with the last drivers)

First of all, I have to say that I have very good performance when I use only one monitor at 1920x1080 resolution, with 70-80 fps, smooth as silk and no stutters.

BUT, the problem is that I have a modest cockpit with two monitors. In the second one, I run some programs that I use during my flight. As soon as I plug my second monitor (no matter if it’s empty) the simulator begins to stutter: Every 1 second or so, it completely freezes for several milliseconds, and then it starts again, with high performance between these stops.

It’s very annoying. I’d prefer having, say, 30 fps without these micro-pauses. I know that probably you will think, “well, the solution is using only one monitor”. But that’s not a solution for me, as I absolutely love the programs that I run in the second screen.

Nowadays, you can find dozens of tutorials in the internet that tell you how to improve performance. But I can’t find little information about how to do the same with several monitors.Prueba3

Have you tried rolling back the NVidia drivers, or better still, a clean uninstall of the NVidia driver, reboot and let Windows update install it. It does seem to fix a few issues. The latest NVidia drivers should only be installed if they have a specific fix or feature supported by the Sim. Most of the time you are better letting Windows install the driver.

Give it a try and let us know how it goes.

Thanks, XR219. Interesting solution. Everybody says that the first thing to do is update your NVidia drivers, but you say just the opposite.

I’ll give it a try.

What are the refresh rates of your monitors? Do they match?
Any gsync or Vsync used?


Yes, Years ago I always kept them up to date from the Nvidia website, but then I realised that often they would just be adding functionality for new games, and quite often breaking existing ones.
In December 2021 for example the completely broke the sim for many people and the solution was to roll back to Novembers version of Nvidia.

Since then, i completely uninstalled the Nvidia supplied drivers, restarted and let Windows Update install the Nvidia drivers. These tend to be older than the latest releases available directly from Nvidia, but they are more stable in my experience.

I don’t use VR or have any other specific requirements from the driver, so while it works for me, it may not suit everyone.

Both monitors are at 60Hz.

They are relatively old, so I don’t have G-Sync or V-Sync. I also have G-Sync deactivated in the simulator.
