How to change from SM4?

When I try to use landscape mode I get a message saying
“can’t create landscape with a feature level less than SM4!”
How can I change this?
Many thanks

I just found out as well,it means that the GPU:
“Graphics Processing Unit” isn’t good enough to support that specific task.
I’m on a macbook air,and it told me the same thing.
So,the only way to change that would be to buy a better GPU I guess.

Конкретно в моем случае движок выдавал такую ошибку когда Preview Rendering Level (в Settings) стояло на Mobile Android.
Изменил на Shador Model 5 - все заработало.
Translated by Google Translate: Specifically in my case the engine gave out this error when the “Preview Rendering Level” (in “Settings”) stood on “the Mobile Android”.
Changed to “Shador Model 5” - it worked.

stanislavEX tnx, it worked.
