As many already know very well, different LOD settings matter. But changing them "on the fly" has until recently not been possible. AutoFPS enables this by dynamically changing TLOD+OLOD, in order to maintain a target FPS. With the right settings in the app, and the right hardware, it is possible to get higher than default TLOD + OLOD. Default is limited to TLOD max 400 and OLOD max 200. And remember: TLOD has a huge impact on CPU load (and probably VRAM), OLOD to a much lesser extent. As I've spent quite some time with this excellent app, I've been able to experiment a great deal with different settings. I'll take this opportunity to demonstrate different TLODs in different situations. TLOD is important as it relates to the terrain draw distance - how far in the distance (both horizontal and vertical) that terrain textures are being fully rendered. On the other hand OLOD influences object draw distance (trees, buildings etc). High TLODs won't matter much at low altitude or on the ground, as one can not see very far into the distance anyway. Conversely, high OLODs won't matter much at high altitudes, as objects are too far away anyway to matter much. How does high TLODs affect performance, I'm sure many people are wondering. This depends highly on hardware, especially the CPU. I have a high-end system and can run relatively high TLODs without having a significant performance impact. Sometimes e.g. when doing scenic flights in GA aircraft, I'm willing to sacrifice performance for terrain detail. I'll show two examples: Lofoten Islands, Norway at 11,000ft. TLOD 1400 OLOD 20 and FPS 50: New York City at 3000ft. TLOD 600 OLOD 1000 and FPS 80: I'll demonstrate the IMHO quite significant difference of different TLODs in various common situations: Runway detail Final approach Overflying a photogrammetry city at low altitude Looking at mountains from low altitude Looking at mountains from high altitude To obtain the highest TLODs in the following images, I had to reduce my target FPS. So the highest TLODs shown are mostly for demonstration purposes. Runway detail TLOD 50: TLOD 400: Final approach TLOD 50: TLOD 400: Overflying a photogrammetry city at low altitude TLOD 50: TLOD 450: Looking at mountains from low altitude TLOD 400: TLOD 600: Looking at mountains from high altitude TLOD 400: TLOD 975: To easier see the difference, click on the images and use the arrow keys on the keyboard to switch between them.
