Aspire 3 A315 21G 2GB Dedicated VRAM underutilized?

ArilAfiq · June 2018

When I open up task manager and look at both the GPU 0 (Link 0) AMD Radeon(TM) R5 Graphics and GPU 1 (Link 0) AMD Radeon(TM) 520 under the performance tab, the listed dedicated GPU Memory are 80MB while the Shared GPU Memory are 1.9GB for both Links. The advertised AMD Radeon(TM) 520 is 2GB Dedicated VRAM, did I misunderstood?
But when I look at the Generic PnP Monitor and AMD Radeon(TM) R5 Graphics Properties, The Total Available Graphic Memory is 2114MB, Dedicated Video Memory of 128MB, 0 System Memory and 1986MB of Shared System Memory. I am confused.

Also during playing games, I noticed that for both Links, dedicated graphic which are only 80MB are used instead the larger 2GB Shared Memory.

Please help me understand.

Shouldn't my AMD Radeon 520 also be listed? I have set the Switchable graphic to Maximize Performance for both on battery and On-Plug
