4K is 4 times heavier than full HD for the GPU, even if you limit the framerate to 30 fps the 1080 Ti will be pretty much always at 100%.

Reduce the resolution scale slider if you want lower GPU usage, however normally being GPU limited is the desired situation.

Your GPU should be pegged at 100% - it's what you paid for and it demonstrates the game is able to 100% utilise the graphics card.

CPU magic numbers are between 50%-70%. Much higher than that and your system ain't up to the game.

As it was already said, 4K is an extremely demanding resolution for pretty much any GPU-heavy game nowadays, and this simulator is no exception. It works vastly different to Prepar3D and the other ones. Even the RTX 2080 Ti would be extremely stressed in such a scenario, and I bet the RTX 3090 will not breeze through that either.

Well, my 1080 is at 40% on neo cockpit, giving an awful performance (14 fps). I would prefer it working at 90% like in external view with 36 fps.

So, believe me. It working at 100% is not the worst kind of issue.

I'm not having much success with 2020. I'm running a 4K monitor and I know that has some impact, but blimey, I fail to see why my GPU is stuck at 100% load most of the time. I have hyperthreading turned on. Trying top get smooth performance with frames above 30 is proving a trial. Settings are set at high, with many options switched off. Has anyone any idea why my GPU, especially a 1080ti, is loading out like this?

Hello Howard,

 

it is interesting to read about you GPU struggle, I have the same GPU but older CPU as you can see in my specs. I run 4K and high preset (tested also some ultra settings and GPU handled well). After playing with render scaling value I use 100, and scenery detail 120. I use external vsync from nvidia CP (fast sync option), and external FPS limit in Nvidia CP (30fps).

My GPU works between 70-90% it never reaches 100%, even over NYC,London etc...I’m very surprised by smoothness, which I didn’t expect. CPU HT “on” removed pauses,stutters, but GPU was always handling well High settings. In Nvidia CP I also enabled threaded optimization and set max performance under power option. I don’t use antivirus.

Some interesting posts, thanks for all the replies fellas, appreciated. From my way of thinking, if a GPU is running at 100% then there would be some strain on it... clearly from what has been posted here, my perceptions are unfounded. I have to say though, as much as I love my 4K 43" monitor, it looks beautiful, I sometimes question my decision as I often fight for good performance. Most of the time in P3dV4.5 things are great, very rarely do I have an issue, but from my first tests with 2020, it is appearing that it struggles, and I wonder how it will pefrorm when PMDG release their NGX.

This sort of usage is only harmful to a GPU if you're stressing it 24/7, like for mining or folding workloads. For standard consumer usage like gaming it's fine as long as its cooling is good enough to prevent dangerous temperatures. Make sure to keep an overlay open and check on that while playing.

Why don't you try running at 1080p, and then fill up the resolution scale until your GPU is loaded. You get a less sharp image, but potentially a much better overall experience. People seem to forget that resolution is only one puzzle part of the simulation experience. It shouldn't govern the attempt of getting a fluid sim. The 1080ti is not up to the task of 4K in this sim (at least not with much details), so why trying to crawl up that hill?

This is perfectly normal.  I have the same GPU and see the same thing.

In answer to your question:  because it's doing what it was made to do.  If you don't limit your frame rates, then either your CPU (specifically: one of it's cores) or your GPU will hit 100% (in an ideal world, both would).  At 4k your GPU is the limiting factor.  If you want more fps, you will have to lower settings.  I find 30 fps, on a screen (i.e. not VR), perfectly acceptable for this title.

Sorry if I've repeated what someone else said, but I didn't bother reading the other comments.

My 1080Ti is running extremely good  @4K HDR. 43" Samsung TV. Using a mix of Ultra and high in game settings. Smooth as butter. I find your statement mis leading, and not factual.

No crawling up a hill here.

Fair enough. I am always seeking maximum detail, and I found the card to top out at around 2.8K. I am not saying it's Ultra on everything, once you get your hang of the settings and their impact, there's a LOT of performance to be found. What's your average GPU load? I usually am around 70%, but it tops out at 100%, without performance degradation. It's those scenarios I think 4K might be a problem.

Smooth is relative. For some people 20 FPS is enough. Others will not accept anything below 60 FPS, or even 144 FPS.

More information on your settings configuration would make your post more helpful though. There are some settings that cause a minimal performance reduction between High and Ultra, and others that cause a huge one. Also setting the resolution scaler to anything less than 100% means that you are not really running at 4K anymore.

Using these settings.https://forums.flightsimulator.com/t/how-to-graphics-settings-and-performance-guide-8-18-2020/132407 resolution scaler set to 100. I have my frame capped at 30FPS in NCP  and native resolution @ 30Hz. Having no stutters, even in big cities is the main goal, not whether you can reach a 60 or 120 fps target. And using a TV, I am hardly likely to aim for high numbers.

My 1080Ti has no dust build up ( only 8 months old ) and it might be generation older now, but is still no slouch.

What bit do folks not understand.

Your GPU should be at 100%.

If your CPU is at anything between 50%-80% then you're good to go.

Your Rig is realising the Game to the utmost.

Go Fly!

Mine is, and very happy about it. Means its doing what I paid it to do
