Rust in OS X is very bad

I am from Russia, and in our country we love rust. So, let's start from my computer.



It is MacBook Pro 15 mid 2014 (MGXA2)

-2,2 GHz Intel Core i7

-Intel Iris Pro 1536 МБ (Intel Iris Pro 5200)

-16 GB 1600 MHz DDR3



And my problem, and problem of many computers.

You need to know, that on my macbook games like Mafia 2, Grid, Assassin or CS:Go work's great with max options.

So, and what about Rust ? It's does't work. Rust does't need so much good graphic or memory, but whet it have much of it, it doest't work.

What problems I have:

-Bag with dark floor (texture) when i have max options

-Low fps (With my mac, it should be 30-60 in middle options

-Bag with sun

-Bag with trees

-etc



So, if someone from Rust read it, please, make optimization !!!



AND ALL MAC USERS, WHRITE HERE YOUR CONFIG OF MAC(OR YOUR MAC) AND YOU PROBLEMS !
