second screen stutter?

[Thekwango]

hola folks - hoping this is the best section for this.....

1 have 2 screens both 144hz (i know mixed resolutions causes funky issues) if i'm gaming on the primary and have a twitch stream open on the second the twitch stream is janky and stuttery as hell when i'm in the game, but tab over to the second screen and all is fine, though fps tanks on the primary screen.

i know mixed refresh rates cause this issue too but struggling to find a fix when both screens are of the same refresh rate.
system specs are ;
3700x
vega64 watercooled
16gb ram @3200 c16
both screens are connected with good quality dp cables and system isn't overly taxed with plenty of headroom.
doing my nut in trying to find a fix as google predominantly brings up results for mixed refresh rate issues.....
anyone had this problem and found a work aroung or fix?

i've tried disabling freesync on second monitor....changing refresh rate on second monitor (read somewhere that changing the second monitor to 120hz fixed it for some folk).....disabling/enabling recording....everything is upto date sriver wise

cheers

What browser are you using? Try turning off hardware acceleration, especially in chrome.

Does it happen in a particular game, that changes your main monitor to 60hz?

oops sorry missed that from my op - tried the hardware acceleration trick too. and happens in most any game i play.

I had a similar issue when I had a Radeon 7970, IIRC I ended up running the second monitor on the iGPU, and disabling windows aero in win7. I did have different refresh rate monitors back then though.

The best fix I found unfortunately was changing to an Nvidia GPU, which fixed it on the exact same setup, before I upgraded the rest of the system, and bought a second 144hz monitor, and switched to win10.

Short of it, if disabling hardware acceleration didn't fix it, I don't think there's an awful lot you can do as it's an AMD card / driver issue, that requires bios editing. At least that's the conclusion I remember coming to when I was researching a fix for this long ago.

EDIT: I never used Freesync, but I know that, and G-Sync can cause issues, make sure that's off on both monitors, and turn V-Sync off globally. I also used to switch between firefox and chrome as my browser of choice, turning hardware accel on / off, I could usually get it to stop stuttering, but it would never just work.
