Yeah, I'd try plugging into the rear headphone jack just to see if the noise lessened or went away. It would give you a starting point, at least.
Turns out theres a headphone jack on the front of my case i just never thought to use before, and its flawless! All the staticy buzzing is gone
I tested a couple more games last night, Alien Isolation runs fantastically. Maxed, at 4K, i got between 30-40 fps. I bumped it down to about 3k i tihnk, and it ran 60fps solid.
Unbelieveably i got almost the exact same results in AC4 Black Flag. I really expected that game to run awfully, as my 770 could barely manage 20fps at 2560x1600.
At 4K it was 30-40fps, soft shadows on low, physx off. Soft shadows really affected the framerate tho even on medium. Took about 10fps off.I could get a full 60fps solid (and this was running around in one of the cities) at 3K.
I do get a bit confused as to the actual resolutions tho, as im on a 16:10 display, so i get these really weird resolutions now like 3360x2400, or 2580xFlubber or something
