New Graphics Card Problems.

[TerrancePickle]

Hey everyone, having some really annoying weird problems with my new graphics card.
I Bought myself a new hd7950 just the other day, installed it yesterday.
HOWEVER, in battlefield 3 no matter what settings i'm on, it wont achieve a stable 60FPS.

At ultra settings (what it should be able to run with no problems), I gets 60 fps in buildings but it drops to around 30 in the open with vehicles and such.

It does this with every setting, even at low it drops to 35-40 in the open.
I've noticed that the graphics card usage never gets to 99%.
On ultra settings the GPU usage peaks at around 75.
On low settings the GPU stays at around 20-30 usage, i have no idea why it would be doing this.
When i stress test the GPU with Kombustor the GPU usage stays at 99% percent with no problems.

Here are my PC specs:

MSI HD R7950
Gigabyte GA-970-DS3 Mobo
AMD FX-8350 CPU
8GB 1600Mhz Ram
1TB Sea gate HDD

Things i'm sure it isn't:

-CPU bottlenecking, The CPU usage never goes above 75% on Ultra.
-Overheating, The GPU never goes above 75 and the CPU never above 55

Thanks for the help everyone.

I'd say your CPU was bottle necking it. Also, what res?

I'd say your CPU was bottle necking it. Also, what res?

It's at 1920 x 1080, so the card is definitely good enough to handle it. I'm sure it's not the cpu bottle necking it, loads of other people are fine with this gpu/cpu combo, and the cpu usage never even goes above 75%, so it can't be that. surely?

There was a thread on here a few weeks ago showing a 2500k getting bottlenecked on BF3 but it not with a 2600k but yes at 1080p you wouldnt really expect that to be the case.

Edit, this was the thread ...

Your CPU could be throttling due to your motherboard..

This is a big gripe i have with the 8*** CPU's they need a proper high end 990x motherboard (£150+) for them to work to there full potental. The motherboard you have while being good is holding the 8350 back due to it being a power hungry chip (more power than its rated for). This in turn is bottlenecking your GPU.

Overclocking your CPU will just back you even more into a corner and may lead to crashes.

Not sure what solution i can offer, sorry.

The 8350 can handle BF3 at >60fps no problem.

The motherboard unfortunately can't handle the 8350 properly (it's not in the CPU support list, even). The VRMs will be overheating. You could ask Gigabyte for a heatsink, which might improve it slightly.

You don't need to spend >£150, an Asus 970 EVO 2 is absolutely fine.

e.g. look at the chips above the socket in your board:

and on the Asus:

It's not the only difference, but essentially no heatsink = no 8350.

edit:

If you don't want to replace your board, if your BIOS allows it you could try disabling some cores.
