June 6, 20179 yr I venture the guess that P3D is now just optimized to use what you have. I have a meager 970 with the usual 4G, and the program is using about 3G of it. If I had more it would use more.

That explains it. It's currently possible to push VRAM usage to the limits of modern hardware. Your add-on and setting choices do not do this. If you turned on all the graphics and scenery settings in the sim you would use more VRAM than your cards have. Since you don't do this, you're probably fine with the cards you have.

If I had more it would use more. That's possible to a degree at least. VRAM usage varies by scenario though. Users have reported P3D using less than the amount of VRAM which their graphics cards possess, depending on settings and add-ons. e.g. 4GB used with an 8GB card, etc.
June 6, 20179 yr Author In P3D V3.0 (never went past it) certain sliders greatly impact my GTX Titan. It's mostly dense clouds, presumably that is the AA issue, and pretty much everything on the Lighting slider. What I've never been clear on is what part of the total GPU utilization is coming from autogen and vegetation and other scenery elements, versus Lighting slider and cloud density. What I end up doing is running GPUeze to display GPU utilization, and back down on those sliders as needed during a flight. Now if someone could make a utility that does that so one doesn't need to modulate lighting sliders in realtime by stopping the sim, that would be killer. And, as well, get rid of AA in clouds that's something that should have been addressed 10 years ago! With what dense clouds can do to the sim I have a hard time believing GTX 1080Ti or anything else will cope with this.
