GPU Usage Spikes Causing FPS Drop?

Hi chaps,

Until recently, I had been gaming perfectly fine on my 'gaming' laptop. Specs are below:

i7-2670QM
GTX 560M
16GB DDR3 RAM

I had managed to get Battlefield 4 running smoothly with a mixture of low and medium settings, and I had overclocked the GPU by a small amount with MSI Afterburner (original core clock 775 and memory clock 1250 increased to 845 and 1575) but yesterday I began to notice a stuttering drop in FPS despite no settings changing.

I purchased X Rebirth and also noticed that suffered from quite a severe FPS drop despite all settings being on low, a friend's 'preview' copy of Assassins Creed Black Flag (yes, I know...mentioning here for emphasis on the issue...) also suffers with a drop in FPS every few seconds/minutes.

I'm wondering whether I have killed my graphics card in some way, as these FPS drops were not happening before yesterday. Nothing else has changed, with the exception of uninstalling Avast and replacing it with Panda Cloud AV.

Having looked at the MSI Afterburner stats, the temperatures for both GPU and CPU look perfectly fine (max of 71, average of mid 60s) but the GPU usage shows an up and down spike of around 94 and then 31 and so on. Every few seconds, it's up, then down, then up, then down.

In contrast, the CPU usage for all cores seems to stay at right at the top of the 90's, hitting 100% every now and again.

Now, I haven't noticed this before. I don't know if it's normal and I just haven't noticed, or whether this is a new issue and it's causing the slowdowns.

Any ideas, guys?

Just to add - I have the latest Nvidia drivers installed, and reinstalled them again yesterday using the clean install option to wipe any settings errors.

what procesess are using the cpu the most when the usage hits 100%? Check windows task manager. I'm thinking the new antivirus software might take a good chunk of the cpu every now and again slowing the game down (ie creates a cpu bottleneck situation so the gpu usage drops). You could just disable it and try the games again...

OK...
Have you tried with stock settings without the OC? At least lower it a little... The VRAM OC seems quite high, maybe it is not stable anymore. I'm not sure how the 560m handles VRAM errors but at least some cards retry the ram operation if it detects an error, so it has a negative effect on overall performance.
