FPS drop when you are next to a C-130 (VR)

[Makakas]

The fps drops significantly when you are near the C-130 and when you look in its direction.(On VR, Pimax Crystal Light)

Same on 2d, old system for me and newer system for friend. 
Best that I can describe it, is that it is in the far to close lod it happens and once "inside the near" it is fine and we did a lot of  close formation. 
This was seen before and after clearing the fxo and metashaders2. Same thing.

Adjust the lod slider in the game settings.

Why not? This will improve your performance.  
 

your other option is to buy a new computer.

Reducing LOD below 1.0 starts to cause some visual issues/quirks.

Because the LOD's seemingly aren't standardised from module to module, things can start to appear incorrectly. Disappearing pylons etc, or some helicopters almost disappearing entirely. It's a bit of a mess.

And if the OP's 5080 is running into this problem, he's only one tier below the fastest GPU money can buy atm. So upgrading the PC might also not work out.

Ideally ED would split up the settings so we could pick and choose which planes/modules we want to be rendered in high quality and which we don't. Or just even separate the detail setting on the module you're flying from all the others. This would help with performance, rather than have them all running on the same setting. But that's been on the wish list for years.

Please adjust per the devs' request. If you see issues with other models, those should be reported to the appropriate developer. If it's the core game, report to us, thanks.

One last comment on this: please, when you report a thing like this, provide me some type of quantification.

The original post says “fps drops..etc”. I mean… yes. If you point your camera at the ocean, and then point it at a bunch of geometry and textures, your frame times will increase by some amount. 

This is because your GPU is doing more work. This is not a bad thing. If your framerate falls by half? That’s bad. 

But if it just changes in a way you find measurable, my advice to you would be: simply turn off the damn frame counter, and enjoy yourself in the airplane.

I apologize for not describing the problem in detail. My friend's FPS dropped from 45 to 5 when he got close to the C-130 and did not rise any higher as he moved away from it.

Hello all,

Thank you for your replies! My apologies for not providing all the details and giving more context - Makakas was kind enough to make a post on my behalf, but I didn't have a chance to chip in yet.
So yeah, the specs are 9800X3D, 96GB RAM, 5080, and DCS is on a new M.2 drive. I also play with a Pimax Crystal Light (PD 1.0, 90Hz, locked in at half frame rate).

Both me on Makakas were on a sever with the Caucasus map, and what was happening is that when I was flying close or over the C-130 standing on the ramp, the framerate would drop from 45 to 5-7 fps (I didn't use the fps counter at first, but the drop was so sharp and uncomfortable that I had to check). 

I'm not sure whether this is an issue with the module, or the core game itself, but since it happened while we were messing with and around C-130, we decided to start here.
I'll try to lower LOD and see if that helps, also will try if it happens without the module present on the server.
