I have upgraded to a GTX 1080, so no- the performance is not impressive but like I said, these scenes have had no optimization done and are purely made to test the foliage models I’m working on- my only personal requirement is to make it run at 30FPS at 4K resolution! I have gotten a Vive recently though which makes me very curious to see if I could make something of similar quality that runs in VR- might go for an all out optimized scene with big foliage texture atlases and crazy LODs but for now these tests are purely for fun/to improve my understanding of how the engine works with lighting. I’ll also try some baked lighting tests with this scene and see how much it improves FPS.
My scene is far less optimal than the Kite Demo- it’s just at a much smaller scale scene so I can get away with a higher density. Also not using DFGI which is a big killer for performance. I keep saying I’ll make a tutorial and then I keep finding more things to learn, so when I feel like I have a good understanding of everything (including creating much more optimized and performant scenes) I’ll definitely be releasing a scene for anyone to pick apart!
Yep, literally everything in the image was created with GrowFX 
That does actually indeed look useful, I might check it out in the future!
