I have a 32 inch 4K monitor powered by a Nvidia 1070. If  I run monitor at 30 hz flight sim and mouse on screen are not smooth, but running monitor at 60 hz resolves the situation.

Is you monitor capable of 60 hz ?

 

Regards Brian

The option isn't on Nvidia Control Center to go to 60hz at the 4k resolutions, only the lower 1080p resolutions. I think I am currently running 1920x1080, at 59hz. 60hz give me stutters.

I'm running a 4k monitor on a 3770k with a 3gb VRAM GTX 780 just fine. I do have to run the graphics sliders at medium settings. Your hardware is fine, something is messed up with your configuration.

I suggest to start:

1) Disable Nvidia Inspector.

2) Then delete your P3D.cfg and your sliders folder, start p3d, let them rebuild, and then run P3D with the default settings. If it runs fine, bump your settings up slowly one by one.

3) If that hasn't cured it, reinstall your Nvidia drivers doing a clean install then repeat step 2.

Almost make sure your monitor has the correct settings and you are connected to the correct input port, this is especially important if your monitor is a TV.

A lot of people have made good suggestions, however you have not provided enough information on your system configuration and addons. Your problem could be either of those.

If you are using Windows 10....well then it could also be a bad forced update from Microsoft.

What I have suggested is just basics to try and clean up your setup. If they don't work you will need to provide more information and dig deeper. The reason you are getting 5 fps is not due to your video card unless it is faulty or has a bad driver or physical install.

Here is what I will try tonight:

• Nvidia Inspector Disabled
• Nvidia Control - "Prefer Maximum Performance"
• Texture_EXP set to 9, NOT 10 (See if this is still visually appealing at 4k)
• Untick "Use High Resolution Terrain Textures" in P3d World Settings
• Vsync On - Tripple Buffer On - Unlimited Frames
• 4xMSAA
• FXAA OFF
• Anisotropic 8x Filtering
• Resolution 2048-2048
• Water Detail Medium

From there, I'll adjust scenery settings. I would like to keep Dynamic Lighting, however, I've always kept dynamic reflections off

I have a Samsung 4k monitor tho I use a 1080Ti I have regularly seen between 8 and 10 GBs of the Vram in use at 4k with a terrain setting of 10, all the important sliders to the right and 8xMSAA (flying either the Twin Otter or the PMDG 737. I suspect if you are trying to run the same visual performance levels of 1920x1080 res now at 4k that is the strain for the 1080 Vram which I believe is 8GBs? I know my 980Ti was struggling with much lower sliders because of the 6Gbs in it. I moved to a 1080Ti from it with my old CPU (3930k @4.4Mhz) and the stutters and loading issues disappeared.

A 1080TI makes a huge difference from the 1080? 

What are heaviest hitters on the GPU? Shaders, Texture_EXP? What else can I try adjusting. I want good visuals, as well as a smooth experience.

Try setting frame rates to unlimited  in SIM and VSYNC on. I don’t use triple buffering coz I can’t see any difference and feel it’s not quite as smooth. (Hard to tell)

Make sure your Nvidia settings are default, delete your shaders and Check your FPS. It should be at 30 if your monitor is set to 30hz.

You need to be holding 30 FPS for smooth stutter free fly’n.

Ive dropped my 4k 65”tv to 25hz to eliminate stutters at big 3rd party airports where I could’nt hold 30FPS.

If you’re still getting lower than 30FPS at a default airport in a default aircraft then you’ll need to have a look at other settings and drop them back. Dynamic lighting and speed trees or high autogen and shadows are big hogs.

As an example I have a Titan X (pascal) similar to your 1080 and have textures set at 4k and most slides maxed out. I use Dynamic Lighting (no speed trees) only MSAA and hold a constant 25 FPS most of the time. My CPU is an old 6800k but OC’d to 4.6.

Im guessing, but your machine should see similar results.

Tried the above, set frames to unlimited, VSYNC but NO triple buffer... same issue

Nvidia was set to default except for "Prefer Maximum Performance" - Same issue, frames hover around 30 for a few moments then drop to less than 5fps, whenever I change external views or start flying

It's very possible you are exhausting your video memory. Are you running MSAA or SSAA? At 4K resolution with a 1080 I wouldn't go higher than about 2x MSAA.

I went down to 4xMSAA. 

I also reset my Nvidia Inspector and NVC to defaults, but immediately changed to "Prefer Maximum Performance"

I run Texture exp at 10. Does 9 make much of a visual difference at a 4k resolution on a 28foot monitor?

I don't care what you do, you're going to have heck of a time getting a 28 foot monitor to run smoothly.  

I got it for a steal! 

I just bought a brand new 4K Samsung 28' monitor today in hopes of getting some buttery smooth frames at a higher resolution... 

My PC Specs, i7 6700 4.0, and Nvidia 1080, 32gigs DDR4 memory, liquid cooling etc. the good stuff :)

I had some problems with micro stutters, and I heard that a 4k 30hz refresh rate monitor would make P3D Beautiful and smooth.

Unfortunately, total opposite case for me... I load up the default F-22, at add on scenery KSEA... I have Vsync, and Triple buffering on.

Smooth for a few seconds 30fps,

then I switch views to spot plane and my frames hit 5fps OR LOWER, and they stay that way... 

So i turn off Vsync a triple buffer, same thing, 5fps or lower in any view, almost as if the sim is freezing momentarily. 

After trying a lot of different things, I'm basically using the same resolution as my old monitor, but on my new 4K capable monitor, which is depressing... I'd love to be able to take full advantage of high resolution. 

Any suggestions, or thoughts on why this might be happening? My system is totally capable, but I'm not sure why i'm having this issue?

Any system or P3D settings you need, just ask.

I feel like this can't be a P3D issue, but a system issue... Is my GPU overloading? I've used task manager to monitor CPU while experiencing 5fps or lower, and CPU usage is very low... surprisingly low actually.

Thanks for your help!
