Ok, weird problem, I've no idea how to fix it.
I have this problem, where on my 7970, it's only using 500-600MB VRAM usage in BF3 (which is causing me to lose frames), the only way to fix it is by deleting the files at Documents > BF3 > Settings (which after doing so, VRAM will shoot up to 1.5GB+). However, that only works temporarily, as soon as I exit the game, go back into the server, the problem is back until I delete those files again. I really don't get it, it has me stumped! The problem only started early yesterday, though it could of been going on longer without me noticing, it was only through noticing I was lacking frames that forced me to monitor the memory usage. (I know this because I always run FRAPS when playing, so I know what kind of frames to expect in maps, so I can compare that to what I'm getting now, plus is feels sluggish now, so it's visibly noticeable e.g. In an empty canals server, I'll get a solid 190-200FPS, with this problem, I'm getting 120-150FPS oh, and yes, I like to run on Low settings to get the most out of it
) The only thing I changed on my machine before then, was the CPU voltage (decrease), and as much as I know very little about hardware specifics, I'm pretty sure the CPU core clock wouldn't have anything to do with the GPU RAM (correct me if I'm wrong)
Another forum suggested that investigate my card PCB for any damage, and so I dismantled it and investigated it the best I could, whilst taking pictures. The conclusion was that there was no damage, everything looked how it should be (the pictures in question: http://imgur.com/a/zdDtR#0). The people at that forum can no longer help me so now I bring my problem here (hence why it's my first post).
What I've tried so far (to no avail)
Full system specification
i7-3770K @ 4.6GHz
8GB DDR3 @ 2400MHz XMP Profile (Kingston HyperX Beast)
MSI MPower Z77 Motherboard
Corsair TX750M PSU
240GB SSD + some more hard-drive storage

What I've tried so far (to no avail)
- Complete re-install of Windows and of BF3
- Cleaned out the drivers and re-installed them (even tried older drivers)
- Disabled overclock on CPU (that's all I had OC'd)
- Installed the latest BIOS
- Tried posting in the Battlelog Tech Support forum, but post didn't receive a reply and is now buried
- Disabled cloud storage in Origin
- Manually installed DirectX
