I just upgraded from GTX 1070 to RX 5700 XT today (Very satisfied with the purchase and happy to join the AMD family) and noticed that while having DX 12 setting turned on in the settings, it causes a lighting bug in “Your Company” menu while inspecting your soldier or while trying to customize your weapon. This bug is fairly annoying as having DX 12 gives me a significantly better performance in FPS (Especially in some not well optimized maps like Operation Underground). Also it’s a problematic bug as I cannot customize my soldier and weapons as well as not having this lighting bug as I can’t make out the details and colors that well :/ And it seems like this bug is only happening on AMD graphics cards so I figured I'd post this problem here to raise some awareness.
I've also posted this problem on EA's Answers HQ and it seems like someone back in JANUARY encountered this problem as well. Not sure why Dice hasn't fixed this problem yet, or it's a problem on AMD's side?
This is a well known issue, safest bet is DX11 for recent Battlefield releases
I tried DX12 on my RX 480 8GB in some games and it did not crash but I did not test any EA games for 64-bit VRAM use recently.
