I have an HP notebook with AMD A9-9420 radeon R5 processor, compute colors 2c + 3g 3.00gz. Ram 12 gb. graphics card: amd r5 (main) 512Mb, R5 520 2Gb Secondary. my problem is when I start games like ghost recon winbleland the game only takes the card of 512 same runs but not fluid, pro evolution 2017 runs but with the main doing that can not play in full of the options takes like vram 512. and so with several games. How can I change the main card for secondary to start from 2 gb not 12mb, how to occupy secondary card?
