GPU usage low, FPS low, how?

[kemperkipie]

So I have 2x Palit Jetstream GTX 680 4GB in SLI, assisted by an Intel Core i7 3770k to give me best gaming performance.....
All powered by a 1050W PSU from XFX

Now my problem is, games like COD:BO2, AC3, GW2, etc play BELOW 60 FPS most of the time, while my GPU usage is around or under 70% at both GPU's. I just can't see why they won't run 100%, and give me a solid 60 FPS gameplay..

I play on 1920x1080 only, with all settings maxed out! Txaa and everything applied.
Why won't my system run it properly?!
GPU temp stays around 70 C at gaming, CPU at max 50 C

I don't see the problem, :S I just want to run it smooth above 60FPS

have you tried overclocking the cpu?

 

[Sunius]

You have to overclock the i7. It will help.

 

[rene13cross]

What happens when you disable SLI? The GPU usage should go up to 100%. If not, then at least you know it's not an SLI limitation/bug.

 

[alvine]

overclock your processor, if the usage on both card increases it means your cpu is the bottleneck

 

[ilumunus]

OC Cpu is probably your best bet, you might be bottlenecking a bit

Eh people, he should still be getting MUCH higher framerates with a 3770k, even at stock clocks!

driver problem?

 

[kemperkipie]

At all the overclock requests: I already overclocked to 4,2Ghz, but my CPU doesnt hit near 100% during gaming.... Besides, some people with worse cpu's max out the games better than me with this i7..

If I use 1 GPU, the usage reached 100%... So I also thought it's something with SLI.. But what can be the problem? I mean, I have 1050w PSU, which is an overkill.. I use 2 SLI-bridges, just in case.. temperature stays safe... I don't see what's limiting them :/

I use the most recent driver, and have tried out every driver they released with GTX680 support... all have same problem.. Had it on Windows 7 and Windows 8... Same problem

 

[Kari]

fyi you dont have to hit 100% on the cpu to be cpu bottlenecked, as long as any thread maxes out its single cpu core/thread it becomes the limiting factor... and with 8 threads on the cpu it's going to be mighty difficult to determine such occasion based on load % alone.
But yeah, you shouldn't be cpu limited...

what's you mobo? have you checked for a bios update?

Disable hyperthreading in BIOS. It might help.

 

[kemperkipie]

I don't have time to test now, maybe later this weekend. But could you explain how this might help? I don't really see the point. I've heard from people disabling it before, especially with overclocking. But still don't get why..

 

[Sunius]

It sometimes doesn't work properly with games.

I have the same problem with my 2500k and 7950. I wonder if u have fond the solution. Please teach me. Ty 🙁

 

[kemperkipie]

No sorry, I guess it's the game... Because some games use around 90~100% such as Crysis 3

Disabling Hyperthreading didn't work as well....

 

[David Li]

I am extremely interested, because if I max out my settings on Crysis 3, I hit 95-100% usage, but I want more frames in multiplayer, so I set everything to medium, and only get 50% usage as a result. Why doesn't the game use more GPU resources to get more frames?

 

[kemperkipie]

I know... I have no idea.......
I just guess it's either the game or the drivers and that I can't do much about it..
So far no luck :S

Bad PSU

 

[angeldeschain]

I have now the very same problem with my two gtx 770s I reached max 60 percent of use and if I low settings the gpu usage gets down too.
Did you find an answer, any solution?

 

[kemperkipie]

Bad PSU

How is that?
How can I test this without using another/new PSU. I don't have one to test.

 

[Taruntj5]

Same here with battlefield 4. Gpu usage go down when I turn down the preset.

are you at 60FPS with VSync?? VSync will stop your FPS from going past 60FPS

 

[kemperkipie]

Since this is almost three years ago, I forgot.. However, I think it the games were just poorly optimized for my GPU at that time, or something like that.
