Help - Weird FPS Drops?

[Zef Pomp]

Specs:
4770k
Evga 780 Ti
16GB Ram
512GB Samsung Pro SSD

Monitor: 27in - 1440p

Computer was just built, everything is on default.

Finished BioShock infinite with no problems..

I then started to play dead space, I am getting major frame rate drops. They seem completely random..only last for like a second or two. I also tested it with Crysis 3 and the same thing is occurring.

On a side note FRAPS is only showing 30 FPS on dead space, it never changes, until a drop occurs..

Hopefully someone can help me out, thanks!

Are those games more cpu bound? Just shooting in the dark though.

Unpark cores. http://www.coderbag.com/Programming-C/Disable-CPU-Core-Parking-Utility

Ah, I need to get on origin and download dead space for free if it's still up!

Not sure about Crysis3, probably driver related.

Disable in-game vsync in Dead Space, and enable in your control panel profile.

@BroHam - CPU should not be an issue

@skiddierow
I disabled vsync and the framerates went to like 150-400, however, the GPU had a bad coil whine...

Enable adaptive Vsync, then Vsync will only kick when the framerate goes above your refresh rate. By limiting the FPS your GPU will use less power (if power management is set to adaptive) and prevent the coil whine.

Beyond that, unparking CPU cores eliminated the stuttering issues I was having in a lot of games. Windows 7 would only use 3 out the 8 logical thread on my CPU no matter how loaded the system got before unparking the cores. My system has an i7-4770 and GTX 780.

I unparked my cores, and that seemed to work wonderful!, no more drops in FPS

Dead space is still stuck @ 30 FPS even with adaptive vsync though

Never saw any stuttering in any Dead Space game on any hardware or os but I never had an i7 until I got Win 8.1 which does not have the core parking issues of Win 7. And it makes no sense that you are getting 30 fps if you have the games vsync off and using adaptive from the control panel. Really there is no point in using adaptive anyway as its not like any Dead Space game will ever drop below 60 fps with even 1/4 the specs you have.

Its a know bug that Vsync doesn't play nice with DS1, I think its because of the poor console port. Have you tried using a program to limit your FPS? I use RadeonPRO, I don't recall the Nvidia alternative.

The NVIDIA alternative is NV Inspector. It allows you to edit every driver flag for any game, including one for limiting FPS. It even lets you reset to factory defaults in case you fudge something up beyond recognition.

Vsync from the Nvidia control panel has always worked fine in any Dead Space game.
