It’s probably because you’re demanding 48fps. Try lowering it until core 0 isn’t at 100%.

What CPU and AM setting do you have?

Ray, but he wrote that he tried minimal settings, and I am sure that with them it is easily possible to achieve 48fps and much more.

I asked him about his power management mode setting in NCP because if you go back a few posts earlier, you can read my discussion with Steve W that if you leave that setting at "prefer maximum performance", core 0 will always be 100% if you limit FPS via NCP regardless of the graphics settings (it doesn't mean that smoothness can't be achieved). Only if you select "Optimal power" will core 0 load be lower if there is performance overhead.

@Afterburner, I have a profile setup for P3D with Prefer Maximum Performance and can confirm core 0 drops below 100%.

But I have a 30Hz monitor with VSync enabled so don't use NCP to control it. Maybe that's a factor.

On an internal flight in Japan here's my CPU loading as I overflew 3rd party Narita at 8000ft.

Yes, your 30Hz monitor in combination with Vsync is an important factor that is not affected by the prefer maximum performance setting. If you want to test, you can set your monitor to 60Hz and limit the fps in NCP to 30fps and check your core 0 load.

Will do but probably tomorrow now.

LATER: Just done a quick check. 60Hz on monitor, 30fps set in NCP, VSync off in P3D. Max Perf in NCP.

Slewing 200ft up at RJAA and then slewing through 360 degrees Core 0 does hit 100% but only when the main airport is in view. It drops to 77% when less demanding parts are in view.

But I'll drop down to Optimal Power as I only set Max when I was having DXGI CTDs and that setting was recommended.

Additional info

The only way I can get my main P3D core to drop to below 100% utilisation is if I am in stock scenery in a stock aircraft. And then it's about 95%. Or else turn down the settings so far to the left that it looks like FSX again.

I don't suppose I can view your P3D settings anywhere, @Ray Proudfoot? Would be interesting to see how mine differ. We have comparable CPUs and GPUs in this case.

I’ll post them tomorrow. I prefer more Ai to buildings so my settings are modest.

But as I said earlier I suspect your demanded fps is far too high. Try 30.

No changes with 24, 30, or 36.

If it isn’t affecting performance don’t worry about it. Post screenshots of your settings if you want further help.

A simple thank you would have been nice.

I've never experienced a complete 100% CPU use, and never messed with Nvidia power settings.  I just vsync in P3D, and set my monitor to either 30 or 50hz as required.  All with max settings, obvs complex a/c raise CPU use but never to 100.

I think I recall @SteveW discussing that CPU counters might not be always accurate with overlays due to some reason or other? Maybe the input from NCP is skewing the CPU use output somehow?

Sorry for the delay Neil. Here are mine. Just reverted to EA off as I couldn't cope with dark cockpit and some runways.

In FSUIPC Traffic I set it to remove Ai once the fps drops below 27. That seems like a good balance between fps for landing and keeping a decent number of Ai (AIG) in the sim.

These are impressive Ray. I've finally made a full reinstall and your settings are just in time to play with.

Thanks.

You're welcome Dirk. Have fun.

@Ray Proudfoot thought I'd replied to this already to say thanks... evidently not. Sorry! And thanks!

Was going to say that your settings are not dissimilar to mine. I guess it's the aircraft that really pushes my CPU hard in the current case. I was able to sit in the default flight with rather higher settings than that with Core 0 at 50%, so it's definitely possible for me.
