Overlays benefit from transparency anti-aliasing. It's most noticeable on overlay grass (High super-sampling transparency anti-aliasing [http://wiki.flightgear.org/images/2/2c/Rotor_downwash_of_the_Aircrane_on_grass%2C_Florence_Airport_%28LIRQ%29%2C_Tuscany%2C_Italy_%28Flightgear_2018.x%29.jpg example]). Transparency anti-aliasing can be enabled in the control panel for NVIDIA and AMD GPUs. However as of March 2020, this is also applied to things like trees. High vegetation density with overlays can cause a bottleneck depending on GPU. Transparency anti-aliasing cantake up a lot of GPU time. This is in addition to overlays being demanding. The Multi-sample (MSAA) option has the best results without too much slowdown. It's recommended. The super-sampling option is slower. If not using overlays transparency anti-aliasing does not make too much of a difference. | Overlays benefit from transparency anti-aliasing.
