Display accelerarion disabled
Is it possible to enable the display acceleration with this PC specs (see printscreens below) or to do something that will stop glitchy previews? It's happening only when the position and scale keyframes are used, and when I'm using for example pins to move parts of the layer, previews are smooth. 
Display drivers are all up to date. I've tried to google out the solution, but I could only find for Nvidia graphic cards, and nothing for AMD.
Also, I've noticed that in After effects I cannot set ray-tracing to GPU (AMD Radeon R9 270x), only CPU ( AMD Fx-6300).
