Does DX12 have a frame rate restriction

Hi
I’ve just tried DX12 again on my system and I note the my FPS seems to be capped at 30fps , it does seem to matter which aircraft / airport.

I’ve looked at my settings and played but nothing seems to make it go above 30 FPS.

On the same settings on DX11 the fps is not capped

Any ideas

No it doesn’t, I get up to 90fps with DX12.

Check settings in both MSFS and NVCP

Have you got vsync on in the game settings or NVCPL?

Had vsync in game , turning it off made no difference, nothing in nivida control panel. Will continue to play
