I just got the best performance from MSFS 2020 on my i5 10400 and RTX 3070 with this new Nvidia Driver 472.12 DCH and two driver settings changes. I did an express installation and had no issues with the driver update.
Yesterday when I ran MSFS 2020 in developer settings I could see I it was CPU thread limited but today someone in this thread suggested going into Nvidia Control Panel program settings for MSFS 2020 and changing the following two settings which I did after updating the driver.
• Threaded optimisation was set to auto but I changed this to ON as recommended
• Low latency mode was off, I set this to ULTRA as recommended
Those were the only changes and the driver update.
Yesterday over JFK in a 747 my fps would drop to the low 20s but actually the stuttering would make it feel even worse like the 10s. I knew something was different as taking off the runway in a 747 from Newark Intl. the fps stayed in the high 30s-40 normally low 20s. Away from the airports fps would climb to 40. I have max frame rate set to 40. Flying low over La Guardia my fps stayed at a steady 40fps. I buzzed the JFK tower with my 747 and the frame rate at it’s worst only briefly dropped to 30 but was mostly in the mid 30s. Landing at JFK my fps only dropped at most to 35. My GPU utilisation was around 50-60% for the most part. This is with cockpit and external views.
All at 1440p HDR on Windows 11 with high settings 100% render scaling 100 LOD, all data on, photogrammetry, live weather, multiplayer, all airport traffic set to 100 etc. I use AiTrack + OpenTrack to provide TrackIR so this isn’t some easy to render static view, there’s a lot of camera movement happening.
I thought it would take a 12th Gen Intel CPU or later to fix the big frame drops at busy airports, turns out a driver and driver settings can have a massive impact.
I recommend these changes too.

DISABLE CPU & GPU OVERCLOCKING (ALL VERSIONS)
We advise against using overclocked systems to play Microsoft Flight Simulator. The increased voltage causes overheating and can gradually damage your computer’s hardware (CPU, GPU, RAM, and motherboard).
If your system is overclocked:
1. Disable Intel Speedstep on your Bios overclock menu
2. Lower or disable your CPU overclock values
3. Disable GPU overlocking for your Microsoft Flight Simulator game profile on Radeon Software or Nvidia nTune (this applies to custom user overlock settings, not for factory overclock settings of the manufacturer)
DISABLE FULL-SCREEN OPTIMIZATIONS
Having your monitor’s DPI set to a value other than 100% can cause issues with Microsoft Flight Simulator. As such, we would recommend disabling display scaling on high DPI settings for Microsoft Flight Simulator.
To do this, follow the steps below:
1. Find FlightSimulator.exe.
2. Right-click on FlightSimulator.exe and select “Properties” from the pop-up menu.
3. Select the Compatibility tab.
4. Select Change high DPI settings and then select the Override high DPI scaling behavior. Scaling performed by: Application check box.
USE GAME MODE
When you’re playing games on Windows 10, Game Mode makes gaming your PC’s top priority, so you get the best possible game performance. For more info, see Use Game Mode while gaming on your Windows 10 device.
