Games stutter (with NO fps drop!) when I have a video or stream playing on second monitor. Please help me friends!

[Andrew Ray]

This has happened to me ever since I got a second monitor. At first, I only had a GTX 780, and I ran both monitors off of that. I recently acquired a GTX 1080. Main display runs off the 1080, second off the 780. The issue persists. I was told once that it may because the monitors have different refresh rates. I set both refresh rates to be 60Hz. The issue persists. No idea what could be the issue. Please halp me so I can actually make use of my second monitor!

I have a 1440p 144hz monitor AND a 1080p 60hz monitor running off of my one Gtx 1080. I went into my nVidia app and set the monitors up as if I was spanning the screens. Everything worked just fine.

Try hooking both monitors to your main card and see if that works. It very well may be a conflict between your 1080 and 780.

aside from 2 video cards what is the rest of your system like ? CPU/motherboard, ram ?

No reason to keep the 780 in the computer unless you need to add alot more monitors.

You could offload PhysX calculations to the 780, but the 1080 is more than capable of doing them on its own.

I tried spanning the two monitors off the one GTX 1080. Max refresh rate I can get is 60Hz so I can't really keep that or notice if there is stutter since it looks stuttery to me lol.

Some of you are saying there could be a conflict between the 1080 and 780 though. But like I said, I've tried using just the GTX 1080 and the issue is still there.

Also the rest of my specs:
i7-4770K no OC
16GB 2400MHz RAM
Mobo: Asus Z87 Deluxe

odd , you had stutter with old video card and now with both cards in , I have a very similar system as you do and I run 2 monitors watching a movie on one and playing game on other and never experience this on one gtx 970..hummm

And again, ZERO frames dropped. Weird :/ Even the animated banners of subreddits cause this issue.

When I get home (at work right now) I'll post a SS of my exact setup.

Have you tried your 1080 on a single monitor and does the problem persist?

The video would be in the background with the game in the foreground and there wouldn't be any effect

Yes and no. Try playing said game in windowed mode and shrink the window. Do the same with said video/stream, too.

Tested. It stutters.

Update: Playing in Fullscreen fixes it. Borderless Windowed is a no-go. Kind of makes using two monitors impossible when in Fullscreen though. Lots of screen tearing in Overwatch, even with a consistent and steady framerate. V-Sync on even produces tearing, so...no matter what I do I am screwed.
