Memory leak while using Nvidia GTX 560 Ti Primary and Nvidia GTX 285 as Physics Card :(

As the title says, i'm currently using the Nvida drivers 335.23, however i have tried the latest available at the time of typing this (337.88) and i get the same issue.

it doesnt matter what version i'm running X86 or X64 exe for BF4.

usually with my 8Gb ram it hovers around 47% total memory usage, however as with any memory leak i get around 100% memory usage.

I have tried the GTX 560 Ti on it's own and i had the same issue, however i did find that when i uninstalled a Logitech G15 Plugin called "SirReal" the game worked, this is also true of the GTX 285.

it just doesnt seem to like running with the GTX 285 as a dedicated Physics card ???

any ideas ?
