Long Frames/Stutters

Recommended Posts

Hi,

I'm in P3Dv5.3 HF2 and I have it working fairly well.

The one thing I've noticed is that I get (I don't know if the term is a stutter or a long frame) every 2 seconds at my FSDreamteam sceneries; particularly KJFK, KLAX and PHNL.  PHNL also has crazy elevation issues after long flights (certain objects floating, on angles, etc.)  I haven't seen this behaviour at any other complex add-on airports.

Is it just that these sceneries are now old enough that the techniques used to create them will always have issue in v5, or could there be another cause?  If the latter, any suggestions on where I start?

i8700k (OC to 5.1Ghz), 32G RAM DDR4, RTX3090, Windows 10 Home 64. 
Using nVidia Control panel to half refresh rate (30 hz), Frames unlimited

 

Thanks,

Daniel

Just try to revert to HF1. I did, and I can fly anywhere without stuttering problems!

I have FSDT's PHNL, KJFK, KLAX, etc., and do not see the elevation problems you describe. I'm also using P3Dv5.3 HF2. It's likely something in your configuration is creating the stutters and elevation issues. Though I'm sure smarter folks than I will suggest better things to try, and not knowing what you've already tried, suggest clearing the P3D shader cache. 2d, suggest researching and/or posting this in the FSDT forum. They are very helpful and can probably pinpoint the problem fast.

Post the [JobScheduler] section of your Prepar3D.cfg. Let’s see if it’s properly configured for HF2.

They are all unoptimised for v5. 

Compress the textures, turn off msaa.

Also, considering trying to monitor your CPU individual core usage using something like Project Ted Lasso. 

It could simply be that you're pushing 100% on the main P3D core, which would cause stutters when loading is needed.

For FSDT sceneries, you will have issues if you use 1M or 2M texture resolution.  Stay at 5M or higher.

It has been like this since the FSX days, and many of their sceneries for P3D are still based on FSX files.  For example PHNL will have most objects floating above the ground if you use 2M mesh.  Switching back to 5M fixes the problem.  Also causes issues with KDFW.  Here is a link with more information:  http://www.fsdreamteam.com/forum/index.php/topic,24718.0.html

Just uninstall client of HF2 and install client of HF1.

That's all

Hi Ray,

Thanks for the offer - I haven't done anything with this, it's honestly confused me.

I had the mesh set @ 1 or 2m to hopefully get around the issue at KSFO (RW28L) where the plane slams into the ground crossing the threshold.  I think I'm still safe there @ 5m, though.  Thanks for this.
