I def do see a difference between my 2gb ddr4 apu vega 11 graphics (ryzen 5 2400 g) and my rx 570 8gb asrock card in game. mostly in depth of field and the crispness of graphics.
But there was a real issue i was hoping to resolve with my upgrade that wadn't resolved. While playing eso during the jesters fest we would make the teleport runs from auridon to skywatch and then to the college and back to auridon. Regardless which grapchics setup it seems though, the result is the same. A loss of texture around the auridon wayshrine. THis was taken just a little while ago with my fancy card installed.
