Yes, UE4 looks far better here. The cryengine screenshot actually looks like its all billboards.
Also, you have to keep in mind that speedtree has quite some stuff enabled by default that eats a lot of performance. Mostly the speedtree wind, you definitely have to disconnect that for all materials (not just the leaves) and also the color variation which aren’t few nodes when you look at it, so those also eat performance. And you definitely see that cryengine has no color variation there.
