I have a multitude of freeware and payware addons for MSFS2024 and I'm guessing that they include a lot of 4k textures that must be hogging my nvme drive and causing performance drops.  Can anyone tell me how I can identify these and the easiest way to reduce them to 2k?

FSLTL of course has a lot of 4k textures, but I've decided to leave these be for the time being as I read somewhere that after converting them to 2k, the json file had to be recompliled, though I'm not fully understanding why this is the case or the easiest way to do this.

Thanks to anyone who can shed a bit of light on this for me.

Full HD only here ... and FSLTL@1024

Thanks, yeah I saw this and I believe I tried it out on the fsltl textures and have ended up with a few pink planes.  Not sure if it can be used with sceneries or is just for fsltl textures.

I do all my paints at 4k - lower looks bad.  Sometimes I'll even do a few textures at 8k.  So if you have any of my paints you'll see higher vram usage.

It's a good thing i don't have any of your repaints then Ryan 😄.  Thanks for making that point though - perhaps I would be better off keeping my textures as they are then.

First of all I do not use MSFS 2020 very often, not sure how this will work.  I do use P3DV5 and the best program for resizing P3DV5 DDS textures is the freeware Paint.net program. I did try one image from the MSFS 2020 default Cessna and it seem to work.  Backup your original image just in case something goes wrong. Load the image in Paint.net, resize and save.  I save the new file as a BC3 (Linear, DXT5) file.  Let us know how it works.

What texture resolution do you have set in MSFS2024?

I understand that, unlike FS9/FSX/P3D (that set a max resolution), MSFS sets the level of "downgrade" to be applied. That's why I find 1024 px textures for traffic awesome in FS9, decent in FSX/P3D and a blurry mess in MSFS, all in the same 1080p monitor.

Texture Resolution is at Medium

Would you mind explaining your reasoning for the 8k textures? I would have thought that with a 4k monitor there would be no discernable visual difference between 4k and 8K textures and I doubt that there would be many simmers with an 8k Monitor or TV.
I would have thought 8K textures is really just using up resources.

Thanks Ryan.

I use 1440p as my monitor.  On some aircraft such as recent carenado addons, the fuselage texture is just one giant texture.  If that's the setup I absolutely have to do 8k to make the curves sharp.  On some 24 native aircraft there are hundreds of textures.  In this case 2048x2048 is totally fine.

Thanks very much for the explanation.
