big drop in fps with gtx 680

[johnlewis804]

Hello

I have a MSI GTX 680 2GB. In every game i play it seems I always get a drop in FPS. I can be at a steady 50+ fps and then all of a sudden it drops to 30 and sometimes to 15 fps for a few seconds then it climbs back up to 50+.

Current System Specs
Windows 8
AMD FX-8120(3.10 GHz)
Nvidia GeForce GTX 680
MSI 760GM-P34
8GB DDR3 1333MHz
Corsair GS600 600W

Find a tool to monitor your GPU frequency, if the card was defective it might be forcing much lower frequencies (lowest is around 300MHz).

Drops in frame rate are also common but it also could be the game, the CPU, or even a software glitch causing a bottleck.

Was it working BEFORE and suddenly now it's not?

When I monitor my gpu with Afterburner i can see my power % dropping and then my frame rate will drop also. Once the power % goes back up I return to back to normal fps

It's the GPU FREQUENCY that you need to monitor (in game or Close and look at the history). The power could vary I suppose, but the GPU FREQUENCY should stay between the BASE and BOOST frequency (example 1000MHz to 1050MHz) while gaming.

If the GPU FREQUENCY drops far below the BASE frequency during a game then you have a problem which may be the card itself, and I think this information is more useful to report to the manufacturer.

Other:
1) run the game with VSYNC OFF if you haven't been to prevent VSYNC from resynching at a lower refresh rate.

2) Also try enabling "Prefer Maximum Performance" for the game in "Manage 3D Settings" of the NVidia Control Panel.

Don't do #2 globally. It should force the GPU to run at the base/boost clock rather than the 2D idle mode. However, probably pointless to force this if your GPU FREQUENCY isn't dropping below base anyway.
