March 22, 20179 yr I wonder, what is the actual visual impact (if any?) of running with Maximum (compressed texture files), or Maximum (no compression)??? I also wonder what the FPS impact might be between the two. I have tried both, and I don't truly see any real degradation of visuals, when running in compressed mode. Is there actually? A heapful of 'wondering' going on.... (rubbing chin...)
March 22, 20179 yr Moderator My understanding is that the texture compression option will convert/compress images into DDS compression when loading. See http://www.x-plane.com/kb/texture-compression/ So without this enabled, the images will be used completely uncompressed, resulting in possibly faster loading times, but much increased VRAM usage.

Ah, so, if I understand your explanation, if you don't see a large pause/lag in loading scenery in front of your position, or any pause/stutter, perhaps it is a good idea to just run in Maxium (Compression Mode), rather than uncompressed, if there is no true visual 'hit' for doing so. Thank's Tony!

If you have a graphics card with a lot of VRAM and on the same time don't use heavy scenery, you probably won't notice a FPS impact. But go, for example, to Drzewiecki's New York City or Miami with only a 4 GB card and uncompressed texture files, and you'll notice that 4 GB VRAM are not enough, and that will FPS suffer.

I'll play around, I did read on Tony's supplied link that using compress mode, does reduce visual quality, but...if you can run at a higher tex resolution, it can actually be better visual output, etc. So I guess one has to just run compressed, or uncompressed, and see if they can pick up any degradation. I might just log a couple of same flight path sessions with Max_Com and Max-Non com, and see what the average FPS on the flight will be, etc... visual quality of: airport at taxi, and at altitude...look for an A/B.... Thanks for all comments on the query, gents!
