Graphics cards
show user profile  antoin_currie
What cards are you running for rendering?
I used to have an nvidia GTX 275, I know it's just a gaming card but it wasn't bad at rendering in mental ray.
It was a lot faster than my current AMD HD 7870, which is just terrible at rendering.
It's also not that great in games either so I'm looking to upgrade soon.
Maybe to a GTX970 of some kind.
Anyone have this card?
I want a good all rounder, one I can use for gaming and rendering.
I'm not going to buy a quadro or firepro as I can't afford them and don't do enough rendering to justify it anyway.

All comments welcome!!

cheers

I've got the Asus GTX970

http://www.asus.com/uk/Graphics_Cards/STRIXGTX970DC2OC4GD5/


I could not be happier with it. It runs cool, fast and quiet. For most games, it doesn't even need to use the fans, the cooler is that good. When the fans come on, I can barely hear them.

It is fast. I've run all my games on ultra, or highest settings, and I've not had any slow-downs.
It's got 4GB or RAM, which is fairly good for GPU rendering.

However, your graphic card makes no difference to MentalRay render times.

Hey Nik, ive been reading into the 970, it appears to be wider than normal, do you have a special case of some sort?

Hey ijzerman,

It's a double-height card, so it will take up two PCI spaces.

However, my main problem was the length. It's quite a long card, and although I did some measurements, I had to flex my case slightly to get it into the slot. It's fine now it's in, but I can see it being a problem for people with small or tight cases.

This is the case I have:

Hi, thanks for the info!

About the Mental Ray rendering, it doesn't use the GPU at all?

I upgraded last year from an AMD phenom 9900 something or other to an intel i5 3570k OC to 4.2GHz and I swear to God my rendering times are a hell of a lot longer than they were before that.

That's why i assumed it was my graphics card, thought that nvidia with CUDA support and all that was making the difference, when my AMD card doesn't have CUDA/.

You're welcome!

MentalRay won't use the GPU for rendering yet*


* Unless you are trying a hidden, prototype feature: http://blog.mentalray.com/2014/07/07/mental-rays-gpu-accelerated-gi-engine-prototype/

Just can't believe that old CPU was faster at rendering, maybe my work just wasn't as complex!

Yes, unless you are using a renderer that uses the GPU, a new video card won't make any difference in the rendering. It will help viewport speed though.

>>Just can't believe that old CPU was faster at rendering

if it was a x6 phenom then its not that far fetched, running at the same clock it would beat a quad core IB chip by ~5%
