I also picked up an ARC 770 , but it's terrible in SWTOR , im running at 4k. I previously had a GTX970 and run smooth at High settings , i cant get a playable experience at Medium due to almost a stuttering effect.
Has anyone had any success with settings and or work arounds. Im on 4257 driver.
Currently looks like it will have to go back and i will have to spend more cash to get something that works.
Thanks in advance.
