TurfFX Effect Layer
The TurfFX Effect Layer is an Effect Layer type which is used to render grass (and similar foliage). As with all effect layers, turf is painted onto the terrain and automatically generates appropriate geometry for the area surrounding the camera. As compared to the Clutter Effect Layer, TurfFX offers less flexibility but substantial improvements to performance which in turn allows for greater density at greater draw distances and effective wind-synchronised animation.

Hardware Limitations
As an NVIDIA-provided visual effect, there are some hardware requirements and limitations which apply to TurfFX.
1. TurfFX is currently supported only for Windows.
2. TurfFX requires a GPU with substantial amounts of VRAM. Whereas Trainz will typically run (albeit slowly, or at reduced settings) on below-spec computers, TurfFX may need to be disabled entirely in the GPU is insufficient.
Trainz offers a fallback mode which effectively replaces the TurfFX layer with an equivalent Clutter layer. This results in a weaker but still acceptable overall visual result. Alternatively, the user may opt to disable TurfFX entirely, in which case the TurfFX Effect Layers become invisible.
