Hello there - so quickly some details. I originally had the "reference" RX480 on launch but got returned due to under performing. Recently I got a new Asus Dual RX480 4GB and have been getting slightly different issues to the first, reference one.
Previously I had an MSI R9 270X 2GB and it was working flawlessly. My PSU should be good enough since the R9 270X draws similar or slightly less power so I honestly don't know.
So, in this instance, the card feels to be under-performing but not FPS wise, instead it's jittering / stuttering very frequently in almost every game making it feel like the fps is way below 60 or whatever the game is currently performing at, feeling like more of a 25-35. Every game is played in boarderless windowed mode at 1080p. Radeon settings is also frequent crashing on opening the WattMan tab, this usually happens the second time I open the tab.
Here are some games and performances pulled from memory to help with my PC specs.
FX8350 4.3Ghz, 8GB Corsair Vengeance RAM, Asus m5a97 r2.0 Mobo, 500W Corsair builder series CX500M, Win 10 - Lastest update
Witcher 3 - High preset - 48-56 fps - Major jittering at times.
GTA 5 - Mostly High with a few ultra, MSAA x2 - 52-60 fps - Also major jittering.
Dirt Rally - Ultra preset - 60fps - Not so frequent jittering.
League of legends - Medium settings (preference) - 120fps - jittering every second or so. (Gif: http://imgur.com/voihMBp Notice the stuttering at a locked 60fps due to trying to see if V-sync would help)
Upon installing the card I used DDU to remove any 270x drivers and installed the RX480 fresh. New up to date drivers. I tried removing the drivers again and starting over however I get an odd error trying to remove them that I don't remember currently. I've tried increasing the cards power limit, decreased the stock frequency and currently... just out of ideas.
Sorry for the long post, and thank you.
