So my brother recently got an Asus X550iu with amd Rx460 (4gb) gpu and r7 (1gb) integrated gpu, but many games just detecting the 1gb integrated gpu for example watch dogs 2 (yeah not a good title for amd, only got like 15-20 fps with lowest setting), but this also happened on rome 2 total war, which also only detect 1gb of vram. can i somehow disable this switchable graphic nonsense altogether and just forcing the notebook to use the rx 460 card?
