Hello.
I have a laptop (Asus X550IU)
CPU: AMD FX-9830P Radeon R7
Display adapter: RX460 4Gb
RAM: 16 Gb
---------------------------------------------
The problem is Display adapter
It uses only 1 Gb of 4Gb RX460
In the AMD UI it shows correct value but I can never use that amount.
It seems I have only 1Gb GPU memory.
More details Screenshots below.
