Indigo Renderer Forum

hi guys.my question is that if i have a quadro graphics card will that acelarate my render?and by how much?if somene have experience with this matter that could share would be great. and i know that is a long shot but is it possible to soft mod a graphics card from a notebook (geforce 8600 256mg) so that it would work like a quadro (a weak one lol) but would help in doing the render faster?
Thanks in advance

David

nope, graphics card isn't used at all by Indigo.

thanks for the quick reply ono:).
Too bad.
and if i use windows 64bits in a quad or dual core and indigo 64 bits will there be an increase in render speed against the 32bits version?if yes how much?

Thanks ofr the answers and thanks for indigo;)

David

Yes, and about 10-15% in my tests (Ono has seen similar)

You'll get another ~5% out of Linux 64-bits vs. Windows 64-bits, as well.

thanks zsouthboy. hmm im becoming more atracted to change to 64bits operative system with 4 giga ram but my bigest concern is sketchup not using the full 64 bits and with no big diference between one and the other and beeing my work tool of choice im basicaly just changing for better render speeds. is there many incompabilities with 32 bits software on windows 64 bits?

Nope, 32-bit on Windows 64-bit works flawlessly. You'll have two "Program Files" directories, one for 32-bit programs and one for 64-bit, but you shouldn't notice the difference otherwise.

Some drivers, especially for older stuff, *could* make problems... (as they often aren't updated any more....)

What about a 64-bit linux distribution just for indigo that can be put on a usb pen drive and booted to, so the user gets this 20% increase in performance (64-bit vs 32-bit and linux vs. windows) without having to totally install a new operating system?

That doesn't sound that complicated with all the various distributions out there, and I could probably do it myself in a weekend, except that I don't really used 64-bits on my own desktop....

Would anyone be interested in this?

I'm a 32bit/32bit windows user and I'm interested in a linux+Indigo rig on an usb key too, something easy to manage. a prompt for the igs when OS has loaded would be neat (not to forget resume option) !

That sounds like a great idea. I'd try that as well.

Thanks for that, will check soon ! Can Indigo use more than 2GB on Linux ? I have only 2GB but maybe virtual memory is ok ?

Yes, and yes, but it's painfully slower than RAM.

What about putting the virtual memory on the pen drive? Granted, that has a tendency to wear out the flash cells, but modern usb pen drives are pretty resilient and the random read times for them are at least an order of magnitude greater than with magnetic hard drives.

Still a bad idea.

Just buy some RAM, it's cheap!
