Low GPU Usage? SLI 470's

post #1 of 17
Thread Starter 
After I put in a second 470, I've noticed that in a lot of games my GPU usage has significantly decreased. Almost every game I try I experience unusually low usage (such as BC2 - 50-75%, when it should be 90%+). This is when overclocked - when I'm not overclocked, my usage is somewhat normal in BC2 (80%+). I've also noticed these problems in games such as Crysis, Crysis Wars, COD: BO, etc. In Metro 2033 and while running the Heaven Benchmark, I see 99% use constant.

Here's my usage after some Crysis:

I remember with 2 4870's I was almost always pinned at 99% usage, so I'm trying to figure out why my usage with Nvidia is so low. I don't think the CPU would be a bottleneck, but is that possible? I switched from an OCZ StealthXStream 700w to a XFX 850w thinking the PSU might be the culprit, but that hasn't helped much.

Any help is greatly appreciated!!

More powerful GPU's need to use less horsepower

vsync enabled?

Shouldn't I still be seeing 90%+ use though in games like BC2 that are demanding? One of my friends has SLI'd 580s and he is seeing 90% use in BC2, and I would think I should definitely be getting more use than him, since the drivers for the 470 should be more mature. Thanks for the quick response.

Edit: No, Vsync is not enabled.

It's your CPU...

Turn up the anti-aliasing and see if the usage improves

AA is maxed in every game I try. 32xAA in BC2 and 16xQ AA in Crysis.

And amd at 4ghz is not always enlough for that kind of GPU power, even my 480 doesnt spike at 99% in games most of the time, always below that in crysis, bc2, Moh.

My 1075T used to bottleneck my Crossfire 5850's so you're having the exact same problem I had.

The 1055 just can't push the cards to full capacity.

The only time I ever saw 99% load on each card was in Metro 2033 and STALKER : COP when the God rays were about.

Or when I turned on Edge Detect anti-aliasing...

So if I OC to 4.2 GHz I should see an improvement? Or is my only option to buy an i7?
