I had a few people asking me about performance of the grass so here are my specs:
i7 2600 cpu
gtx 570
16 gb ram
I created the default terrain and filled it with the grass completely. They are all being drawn, none culled. It’s also on epic settings.
Before with nothing in the scene I was getting around 60 fps or so, and after placing everything in the way I did it dropped to 20fps.
Keep in mind is using 1024x1024 texture map with no mips, and 3 different meshes being instanced.
Realistically would be a poor use of optimizations for a game, but I just wanted to show worst case scenario of how much resources the grass could use.
