Have you checked the task manager when it happens? Is the BF4 process using all the memory, or is it all 'paged pool' memory?
bf4 starts using a lot of memory like for example goes up to 90%, then I quit the app, the leak doesn't go back to normal. I still have to reboot system. Its wierd that you have the same card, and this fixed for you. While I am still experiencing the same issues.
so this is my fix
downloaded this software called parkcontroldist64
and diasbled both ac and battery. Now all the 4 cores are utilized to max capacity. No memory leaks so far.
I can confirm the registry tweak doesn't work for me. I will give it some more time, but so far, no difference.
