AMD crossfire low gpu usage.

Zobbar · Jul 14, 2014

Hello,
Most of the time, I can't get above 60fps (I'm getting 40-50fps, though sometimes it can go up to 80fps on 150% res scale) on my 60hz monitor. I'm running a 7870XT (tahiti) and a 7950 in CF. As you can see in the picture the usage is very low. I get the same fps on 1080p ultra 100% res scale 200% res scale, and 25% res scale! How can I fix this. I'm using 14.7 Drivers, 14.6 and 14.4 also don't fix it.
Important:
6Gb ram
FX 8320

Thanks for any help!

Sounds like you have Vsync enabled, remember to disable it in-game as well as in CCC.

Eduello :

I don't have it enabled, and what's CCC?

Eduello · Jul 14, 2014

Catalyst Control Center.

Eduello :

Yes it is disabled... Any way for me to fix it?

Eduello · Jul 14, 2014

So the fps never goes above 60? What program did you use to measure that?

Eduello :

Is my stock FX 8320 too slow? Do I need a OC?

Thanks

Eduello · Jul 14, 2014

A stock 8320 should be able to do over 60fps in most games, but you could try OCing to see if it helps.

Eduello :

Oh well before I do that, do you know how I can fix this problem, in total I spent over 12 hours of my time trying to fix it and I'm wanting to throw my PC out the window!
Thanks

Zobbar :

Probably not. Remember that you will only get as fast as the slowest gpu. So the 7950 won't be fully used (Most will)
The amount of ram is a bit low. 8GB is recommended nowadays for gaming. The 8350 should not bottleneck. They are basically 2 higher-mid end cards, not 2 High end ones so it should be fine. Are all the drivers up to date?

Eduello · Jul 14, 2014

What game are we talking about? You could try running a virus scan and shutting down all unnecessary processes.

Zobbar · Jul 14, 2014

Eduello :

Battlefield 3 and 4.

Yes the drivers are the newest?

Any help?

Eduello · Jul 14, 2014

Tried the virus scan and shutting down programs that are running in the background?

Zobbar :

Could there be a saturation in the PCI-E lane? Unlikely but still.
Try to disable one of the cards and see if each can max out without any issue. Do a torture test on each. If they work fine alone, then it has something to do with the crossfire.

This may not be right, but cant you not get above 60fps on a 60 hz monitor? like 60hz maxes at 60fps while 144hz would max out at 144fps...?

Zobbar · Jul 14, 2014

Anheanz :

No you can go above 60fps as long as Vsync is of.
