There's no dedicated GPU. This is the AMD APU and what you are seeing is about right. You should shop around for a nice 1050 Ti card to get out of the basement.
So I bought a pre built dell inspiron gaming desktop and it has a
-Amd a10 -9700 processor
-Radeon rx 560 2gb
-8gb ddr4 memory
When I run fortnite on it, it runs good, I get above 100 fps on all low but I dont feel like I should be running all low settings when I do medium settings I get 60 but super laggy and stuttery same with all low. Is it my cpu or gpu I need to upgrade?
