Has anyone tried Nvidia Smooth Motion on 4000 series gpus with fslabs ?

Hi, what do you mean with this question? Looking at the Nvidia Center, this is a setting only available for 5000 series gpus and it's also meant for "games not supporting DLSS", which both MSFS's support?

With the new developer beta driver it is allowed to turn it on with 4000 series.

In order to use smooth motion you have to turn off DLSS-FG and rely on raw FPS, not sure why I would do that with my 5090 and it has been added to 4000 series but still no point for MSFS unless your game doesn’t have DLSS-FG

I think the only interest in this would be on MSFS 2020 with DirectX 11 (where you can't have FG). But the drivers who supports Smooth motion makes the sim CTD on initial loading with DirectX 11
