[SOLVED] Cannot get DLSS 3 to work with a 4090 in MSFS 2020 ?

Good morning everyone,
We have Microsoft Flight Simulator 2020 running on our sim, with a 4090 and a Ryzen 9 5950X.
CPU is making a bottle neck, we get at 4K Ultra with DLSS 2 in Quality about 70FPS, and the game in DX12 has the option to enable Frame Generation, we enable it and we see no difference at all, it seems like it does not enable.
We have enabled HAGS in Windows 11 configuration, but also it does not make any difference.

Any ideas why that could be? Any setting on Nvidia Panel?

Btw we are running the MSI 4090 Gaming X Trio, we bought it yesterday

Another thing, we also have plugged in a tiny quadro to add outputs for the central displays, might this influence?

Ok, nevermind, the internal FPS counter of the games with DLSS 3 is not correct, as the frames are generated in post, so you must use an external counter, we where indeed getting the correct framerate, but we didn't see it!

cpu bottleneck maybe?

Yeah, we do have a CPU bottleneck, but the DLSS 3 Frame Generation should improve the performance in this case AFAIK, I mean, in fact it is a good feature when you have a CPU bottleneck.

Also I've seen various different benchmarks with this exact build (4090 and Ryzen 9 5950X) that when enabling Frame Generation gets 150FPS on avg.
