Rust weird FPS issue in window mode.

[Spool Lyger]

Hey,

 

I've been trying to figure out why I get very low FPS while playing Rust sometimes. I was playing around with the game in windowed mode and noticed that if I had the game window more to the left of my screen I would get 100+ FPS int he client, but then if I moved the game client window to the right of my screen the FPS in-game would drop to 50 fps. There is literally this vertical line on my screen where if a game in window mode cross that lines the FPS gets halved. I cannot for the line of my figure out how this could even be possible or why. 

 

I'm currently running a GTX 1080, i7-4790k, 16 gigs ram, H97-Gaming 3 motherboard in Windows 7 Pro. I have a 27 Inch Agon AG271QX 144hz monitor with a dual screen setup, the other monitor 24inch 60Hz screen. I have tried disconnecting that screen and it does not affect this weird issue I'm experiencing, I am also running the latest Nvidia drivers which I updated to today as well. No change. 

 

If I place my client here on this side of the screen I get 100+ FPS

If I move the window to this side of my screen I get 50-60 FPS,

Basically, if I move my game client past this red line my FPS drops down to less than 60 for some reason,

So this means I can make my game client this big without any FPS drops, but as soon as I stretch the game client 1 pixel more to the right over where this magical verticle line is my FPS drops to 50,

When I run the game in full screen my FPS is just be limited at the 50-60 range (Full screen and windowed, it does go above 60 from time to time so it's not verticle sync, plus full my monitor refresh rate is 144Hz anyway). Also, it doesn't matter what graphics settings I have the game on, maxed or minimum, even running the game at a non-2k resolution I have this same issue with not getting above 60 FPS, or getting 100+ fps while my game client isn't going past this red line.

 

Does anyone have any ideas what might be causing this?

rust is a weird game, whats your settings in it?

It pretty much doesn't matter what settings I choose. If I turn everything on really high or low I get this same issue with the client running at half its FPS if the game window is positioned to the right of my screen. If I run full screen I just get the halved FPS (50-60). I've definitely had very good FPS in the past but just for some reason now I get really bad FPS all the time. Almost seems like its build to build of Rust that my FPS is either good (120+) or bad (50-60 and feels really choppy, as if it's a lot lower than 50-60)

The real question is, why would the game have 120 FPS when the game client is on the left side of my screen, and then I move the window to the right side of my screen and suddenly I get 50-60 fps?
