'''Transparency anti-aliasing''' (NVIDIA), called '''Adaptive anti-aliasing''' by AMD, is a 2nd anti-aliasing option (article with [https://www.anandtech.com/show/2116/13 explanation] <small>- [http://web.archive.org/web/20150715074320/https://www.anandtech.com/show/2116/13 archived]</small>). Transparency anti-aliasing can be enabled in the control panel for NVIDIA and AMD GPUs. | '''Transparency anti-aliasing''' (NVIDIA), called '''Adaptive anti-aliasing''' by AMD, is a 2nd anti-aliasing option (article with [https://www.anandtech.com/show/2116/13 explanation] <small>- [http://web.archive.org/web/20150715074320/https://www.anandtech.com/show/2116/13 archived]</small>).

Transparency anti-aliasing is most noticeable on overlay grass (High super-sampling transparency anti-aliasing [[:File:Rotor downwash of the Aircrane on grass, Florence Airport (LIRQ), Tuscany, Italy (Flightgear 2018.x).jpg|example]]). However as of March 2020, transparency anti-aliasing is also applied to things like trees by FlightGear. High vegetation density with overlays can cause a bottleneck depending on GPU. | ||
Transparency anti-aliasing can take up a lot of GPU time. This is in addition to overlays being a demanding on the GPU. Anti-aliasing and overlays don't need extra CPU time, and you can try turning them up if you are CPU bound, or your GPU has FPS to spare. | Transparency anti-aliasing can take up a lot of GPU time.
