GCard: GTX600 x1
Render time: 18Hrs
GI: PT

nice image, a lot time 18 hours, maybe you should try use diffuse or AO
regards

Yes, I agree with Merid888 that is quite a long render time. Here are some options for you to try.

* Use diffuse GI or AO as Merid888 suggested.
* Reducing material brightness and reflection where possible, except for things like glass, will speed up render.
* Reduce emitter resolution to low as possible if you use meshes.
* Turn fake shadows on for light to pass through better. Reduces noise.
* Try PMC and tweak to these settings

maxrejects to 100
caustic blur to 0.03
lower the exploration strength
make direct light importance higher

Also very good render .

Thanks.

Awesome shot Royk!

Actually, I tried many ways, ....diffuse GI and PMC, but the rendering time is slower than PT, thats why i chose to PT for final render. ...anyways Thanks you're comments.

Did you output too larger render size than what is currently here.

Lookign great .

BTW your GFX card info seems worng? GTX600 is what ? 650, 660, 670, 680, 690 ???

sure it is long rendertime but for 2+ years single card/GPU not so unexpected either.

Actually this is not true, even if a GPU is older does not always mean less powerful. I previously had a GTX 470, which now is 4 years old and that was a fast card but such a beast in terms of power consumption and temperature and for that I have a GTX 750Ti and I can still get interior renders with PMC in a couple of hours and I use a least powerful GPU than say a Titan. I don't believe it is to with hardware completely, but also it is the software and how it develops that will now determine how fast you can produce a render. Period .

What's not true ? Where did i said that his GPU means it's less powerfull than what ? Can you please point me to part of my sentece what's not true ? Does he have 1 GPU ? YES. Is it 2+ years old GPU (6xx series) - YES. So what's not true here ?

I think you are reading between lines something I didn't say or what you want to believe i said.

Forget it, it does not matter.
