Importance of double precision performance?

Hello everyone!

I would like to know if the double precision performance of a gpu affects rendering times at all? I have heard time and time again that the new tesla cards will be about as fast as the fermi gtx cards. However, because the new tesla's have much more double precision performance ...

Re: Cuda to OpenCL! Read this!

Thanks for your reply Radiance,

Good to know that you have been researching these possibilities. I guess nothing is ever as simple as it seems
(especially if someone doesn't know anything about code).

I am referring to me of course hehe.

Thanks for your input Maryus3D :)

I have heard the same from various sources yes.
However, if this "Swan" program can make it really easy to make the switch; why not offer Octane in two flavors? Cuda and opencl? This way everybody wins!

Re: Please give me some advice (ram)

note that we're working on a new import option in 2.3 that will practically halve the memory requirements for meshes in octane in 2.3 (we hope, halve, or nearly halve),
with no visible differences. (it's optionally however).

We're also working on making the voxelisation stage quicker and consume ...

Re: Please give me some advice (ram)

Thanks for all your input guys, I appreciate it.

I have decided to wait a while, nvidea is just crazy asking us to spend 2,300 euro for a 3gb card. It is unacceptable for me. If I was looking for a solution to just play around with, then sure the 480 would be a cost effective route, however I want ...

Please give me some advice (ram)

Hi all!

I want to create production quality, near photo-realistic renders for animations @ 1080p. Would a memory size of 3gb from the Tesla c2050 suffice? I know it depends on many things, and I would test this out, but I have an ati card at the moment. I was considering getting a gtx 285 2gb to ...

Re: HARDWARE SETUP

TO OCTANE TEAM: in a previous post you told me that i can use 2 GTX480 for rendering and 1 fx 580 QUADRO for displays. IF THE QUADRO CARD IS GONE EFFECT THE PERFORMANCE OF THE 2 GTX (IN TERMS OF AVAILABLE MEMORY) PLEASE CLARIFY IT!!

sorry for the caps but i am in the process of ordering a 4500 ...

Re: HARDWARE SETUP

octane will allow you to use the amount of vdeo memory of the lowest card that's used in a multi-gpu memorry setup.

Radiance

Does the limit cap effect pass on to other cards even if it is the dedicated display card while you have one or more dedicated (not plugged into screen(s) rendering ...
