I can't find any drivers for this card, I am using Windows 10 and need to update to play Company of Heroes 2 without crashes. The AMD site doesn't have this card in it and autodetect can't find anything.
There is no such graphics HD4600...it probably says HD4600 SERIES...which is a series of cards.
What is your processor/APU?
Use GPU-Z and select 'Lookup' it should tell you the exact card you have:
Pressing lookup doesn't get me anywhere, I believe my computer is blocking link pop-ups like that. Here's my GPU-Z window http://prntscr.com/r74sdh
My processor is Intel Core i3 2100 @ 3.10GHz
the best driver is already on windows update
