Sorry if this sounds dumb, but I don't really know much about the hierarchy of graphics card.
I've owned this game for about 1 year now, running on the 11 inch 2015 laptop Mac with the Intel 6000. I had emailed the ESO support about the cursor issue (different forum) and they replied to me saying they can't help me because my graphics card is not supported. I could've sworn that ESO used to support the Intel cards...? Or am I getting something mixed up here?
Also, is the Radeon Pro 560 with 4GB video memory enough (the one in the iMac 21.5 inch desktop)? I really can't tell if it's more/less than the minimum "AMD Radeon™ 5870 (1GB of VRAM) with OpenGL 4.1;"
