AMD Crossfire works with PUBG? :: PUBG: BATTLEGROUNDS General Discussions

So i got an asus rx 480 8gb and was thinking about buying a new one and use them in crossfire. My question is, does pubg use crossfire, will there be fps improvment or will i eperience issues?

However I can confirm that PUBG as of January 2018 foes not support Crossfire, just like it didn't before. I have 2x R9 270X`s, and as soon as I turn crossfire on I get stutter, freezing and about 40% less fps than running just one card.

Looks like you guys have a similar experience. If a game doesn't support CF/SLI you'll see either no improvement, or lower frames. There is a reason AMD/Nvidia has dropped multi GPU support. I would honestly just stop trying to use them both for gaming.
