...vs being turned off completly. Just tested: When zoomed to ground, on map with dense grass, with my computer:Grassdetail is completely irrelevant knorke, because at detail of 3, the grass only renders when it;'s about 10 feet from the camera.
No grass visible: ~100 fps.
Zoom just a bit until grass shows: ~60 fps.
Does not matter so much for me because fps is still good enought, but for some it can make a difference.
