Just bought a new PC - Intel I9 13900K and nVidia 4090 - so a pretty powerful beast - particularly as I had come from a Intel i7 6700 and nVidia 1080.

The previous set up worked Ok'ish - but one thing I noticed is that when I went to external view - I often experienced 'lines' or the screen going black. Strangely when I went back in the cockpit - the views were fine.

Now with the new PC beast - I am still experiencing a degree of the same issue in external view. If for example I set GSX to load, fuel, catering and passengers and switch to external view - I get flickering and sometimes a black screen.

When I take a look -  CPU is at 1 or 2% - yet GPU is at 100% (and remember it is a 4090)

Is there a way that I can share the load between the CPU and GPU in a better ratio? - or is there something else I need to do.

All suggestions and thoughts welcomed and appreciated.

Safe flying.

 

 

 

This is not normal. You shouldn't be getting black screens and flickering!

I have a 4090 as well, along with a 5800X3D, and never saw anything like this. I play at 4K Ultra.

What's your power supply?  

I have a 4090 as well (and 7800X3D) but haven't experienced anything you mentioned.
100% GPU load is extreme.
Also my question would be: what is your power supply?
For a system like you, an 800-1000W supply would be the minimum, as far as I know.
I have a 1000W PSU

Edit:
Maybe install HWINFO and run it (the sensor part) during a flight.

My power supply is 1000w and I am also playing at 4k ultra.................................any more thoughts.

Out of interest - I am connected to the monitor with a display port cable - which I have just replaced - in case that was the issue.

There's definitely something wrong here. GPU should not exceed 50-60%. Is this new Windows? Have you tried other games on how powerful your GPU is?

Yes., I upgraded from Windows 10 to Windows 11 pro

Not tried any other games - as I only play MSFS2020

Do I need to do something with hyperthreading?

Where are are you "taking a look"?  Windows Task Manager?

Also is the GPU at 100% all the time, interior and external views?

Lastly, try setting fps to 30 in the MSFS settings as a test.

Or try to cap frames in nvidia control panel. I have same system as you and don't have any problems. I have frames locked at 115fps, vsync on in ncp, dx12, frame generation on in sim.

Same here. Same system and very similar settings and I also do not have any problems. 

A 4090 running at 100% seems really strange as others said, unless you also turned up resolution scale to something like 200... Besides this, screen turning black and flickering might be more related to your monitor setup. What kind of monitor do you have? Do you have G-Sync active? Did you change anything regarding Hz numbers of the monitor?

I ask because for me, it took me quiet some time to get rid of the flickering which was due to my freesync pro monitor using G-Sync. Now I found a setup that is somehow working for me, still some tests to do.
