    Problem still exist on Unity 2019.1.8f0 ...


    3 Layers painted on it
    1 sort of tree made with Speedtree (a small Bush)


    AMD-FX 8320e 8 core
    nVidia GTX 970 4GB
    32GB DDR3


    CPU 1%
    RAM 18%
    GPU 2%

    Cant see why there is a frameratedrop to 13 fps because GPU and CPU is almost doing nothing.

    AMD FX 8350 4.0 ghz, 8 gigs ram, Radeon HD7850 GPU 2gb video ram.
    Getting 16-30 FPS at 1920x1080 Max Settings in Rust. Fewer trees = better FPS.
    Please focus on this problem asap as it appears to have been reported in 2013. :(

    I'm begging you to focus on this issue, it would really improve performance of your engine.

    Please fix this. Severely regretting that we switched to Unity 5 because of the performance hit. : (

    Please fix this. It makes Rust quite an issue for most players

    This is the main problem me and the company I work in are dealing with at the moment, please fix this, as it seems like this ambitious shift to Unity 5 is not a good idea on our part so far.
