GTX 680 4gb renders really slow

Hi, I was checking this thread
http://forums.creativecow.net/thread/2/1019120
and i decided to test my graphic card. The problem is that it renders very very slow and i dont seem to understand what im doing wrong here. I have GTX 680 4gb/ 32 gb ram/ i7 3930k (12 threads)/ intel ssd. Its a good system and i render that benchmark scene in around 7 minutes.. Is there something wrong with my graphic card or im missing something inside AE? thanx alot

How about providing us with EXPLICIT details of the scene?

BENCHMARK AVAILABLE HERE - http://www.teddygage.com/AEBENCHCS6/

Its this scene from this post: http://forums.creativecow.net/thread/2/1019120

I see others people's posts here that are half time than mine with much worse cards. I also noticed in GPU rendering in 3ds max that the times im getting are twice than others. So then i tried to do a bench in AE regarding my GPU and i saw same bad results there... I dont really know whats going on. Maybe my card is faulty? I dont think is a coinsidence that my render times are slow in both max/ae. Can u do a quick test on that scene? Im using CS6 latest patch/windows 7 x64. I need to do something inside AE settings for my GPU? I just wanna make sure that all is good in terms of settings in order to say that my GPU has problems. thank u very much

The difference in the render time of Benchmark Scene is just of few seconds(comparing your render time and the one posted in thread listed above). It is normal to get this much difference as the rendering speed also depends on many factors and not just on GPU and CPU speed.

By this I mean that how many applications you are running while rendering the file also counts.

Another factor that counts a lot while rendering is Multiprocessing.

Since the difference is of just few seconds. Don't think that your System is slow.

Vishesh, thanx for ur quick response. Well is not seconds is like 50% down. Check this:
"Okay finally my new GTX 680 4GB Phantom arrived and i did the same test again.

Win 7 64Bit
Intel i7 2600 @ 3,4GHz
16Gb Ram
GTX 680 4GB Phantom

2 Min 49 Sec"

This is half time from my system. I have nothing else open, i just have skype and my browser. This is so weird. Also when i do VrayRT (gpu rendering) i m like 50% slower than other benches i tested. Btw, since u mentioned multithread, i get this message in the specific scene: "incompatible artisan, multiprocessing disabled".
Despite that message which has to do with Raytrace engine,maybe something has to do with my drivers? Cause with new nvidia drivers i do the scene at 7:30, with some old drivers i do it on 6:10... Is huge difference if u see it like a percentage. And is far from the 3 or so minutes that i read from others. I mean i must have a huge bottleneck in my system or my graphic card is working on half of its power. Im certainly im missing something here but idk what :( thanx for ur help

my mistake. I didn't go through every post. I just saw the first one.

Btw, since u mentioned multithread, i get this message in the specific scene: "incompatible artisan, multiprocessing disabled".

I wanted to know whether you have Render Multiple Frames Simultaneously ON or OFF. Turn it OFF if it is already Enabled. Since you have just one GPU, there is no need for it.

Also Do you have the latest updates of AE?

Update AE
Check this article about GTX6xxx series:

http://www.studio1productions.com/Articles/AfterEffects.htm

There is information about the New Drivers too.

Hope it may help.

2 thoughts:

Do you have anything else plugged on that machine that could be using your PCIe bandwidth?

Is the GPU connected with that auxiliary power source cable?

If it ain't that, I don't know.

I started checking these things out last night, and i noticed that my pci-e was 2.0 instead of 3.0. I read some articles about that and i fixed it. NVIDIA disabled somehow the 3.0 from 680/670 cards for more stability in speed. I fixed that anyways but it said the only difference in speed i could see would be if i was using SLI.
Concerning power, i use a 1200W psu. How can i check if the card gets all the power it needs, with some software or something? thanx a lot guyz

ps.vishesh, i ve done all these things i read, which werent neccessary cause the card is new. I ll keep looking into it though has some very useful tips.
