Low FPS with RTX 3090 and AMD 5950x

you have your MSFS resolution equal to the native resolution so no upscaling is happening. MSFS is rendering the screen to the full resolution of your monitor so essentially eliminating any performance help DLSS could provide.

This isn’t how DLSS works. DLSS will render the sim at a resolution lower than your monitor resolution, then use AI to upscale the resolution to the same as your monitor. You can see this in the FPS counter on the Dev Mode. With DLSS enabled, your render resolution (which is what the GPU renders at) will be lower than the screen resolution. There’s nothing special you have to do regarding resolution.

Another user asked something similar awhile back, perhaps this can be useful.

FPS counter interpretation

The screen resolution is the resolution pushed to your monitor - the render resolution is the resolution rendered by your GPU. If your render resolution is less than the screen resolution, you either have render scale <100% in your graphic settings or have DLSS enabled. DLSS will render at a resolution below what’s set, then use AI to upscale to a higher resolution.
