Choppy Camera in Games

I recently purchased the MSI GS70 Pro w/ GTX 870M, and a problem I've encountered is that in some games (FPS games are the best example), although the framerate is up to par and the games run essentially lag-free, the camera is very choppy when I turn the screen to look around in the game. Moving the camera diagonally, it moves in a jagged (zig-zag) path rather than smoothly.
Some games in which this happens are Bioshock 1, Bioshock Infinite, Battlefield 3 (although there's no issue with Battlefield 4).
I'm using the same mouse that I used with my MSI GT60, and I did not have this issue with the GT60. I've scoured the interwebs for a solution but can't find a concrete one. Please help :cry:

 

It might have to do with the GS60 overheating like hell (especially the CPU) resulting in throttling and unsteady CPU/GPU frequency.. I would honestly return it and hold on for 1-2 months as there will be a new GS60 with NVIDIA Maxwell cards which should run much cooler and have much better performance overall...

 

Thanks for your response.

It's not caused by the throttling issue:

Firstly, I've applied the following modification using Nvidia Inspector to cap GPU temp at 90 degrees, which is below the 93 degrees throttling temp: https://forum-en.msi.com/index.php?topic=182568.msg1311345.

Secondly, I've put together a cooling modification consisting of several fans that bring the GPU temperature down significantly below the throttling temperatures ( http://forum.notebookreview.com/msi/760098-msi-gs70-stealth-pro-2pe-024-mod-2.html)

Thirdly, the choppy camera issue is occurring while the games are running at a smooth, high framerate, and while temperatures range from 60-75 degrees, which is far below the throttling temperatures of 90-93 degrees (mostly thanks to the cooling mod).
In fact, several more demanding games bring the GPU to a higher temperature (mid 80s) and yet I don't experience a choppy camera with those games.

 

And what about CPU temps?

 

The CPU is always below 70 degrees

 

Anybody ever thought it could be screen tearing? Most FPS games are gonna run way above his 60Hz on a 870M.

 

I avoid screen tearing by enabling vsync (the choppy camera occurs regardless of vsync). It doesn't look like screen tearing anyway, because when turning the camera, the frame is always in one piece rather than torn.

 

Do you have Skype open and/or getting messages while gaming? Skype has been known to do that (by me) on some games. Otherwise, I don't know really. I just know I've had choppy-ish feelings (though the game is running at the correct fps) when some things trigger it. Also, windowed mode may do it in some games (SSF4 AE 2012 and USF4 do this)

 

I run all games in full-screen and without Skype. I don't record my gameplay either. Thanks for the ideas though.
