Hi there, me and my brother both have a amd laptop with r4 graphics. He has the laptop with amd Pro a4-3350b apu with Radeon r4 graphics (512mb) and his r4 driver date is 21.03.2017. I have my laptop with amd pro a4-4350b 5 compute cores 2c+3g with r4 graphics (128mb) my driver's are upto date. And btw there's a huge difference in applications his laptop ran a game with 60fps performance while my lap strrugles even to open the game. Also my editing softwares run very slow.Is this the problem with the dedicated vram? Should i downgrade to 2017 version to get 512mb?? And btw we both have 4gb sodimm ram
