Hey everybody,

i've got some problems with my AMD Radeon R9 390.
Everything is working well, but the screen is flickering.
In the options i saw that OSX is using just 5mb of my vRAM.
But how can i change it? I already tried to install the .ROM file of my GPU,
but i did not know how it works.

Can you help me?

Thank you!

Some ATI Radeon Graphics cards have problems. You may want to check this guide out. Radeon Compatibility Guide - ATI/AMD Graphics Cards Hope this helps.

Thank you for your quick answer!
I already tried to do it with this guide. But most of the things did not work (or i did not understand them as well)....
