VRay Speed - I'm not seeing it?

I've been using vray for about a year now but not often enough to have gained enough knowledge to work the program efficiently. I have some rendering settings that I've pulled together from various posts across the internet that have served me well with results but require a huge amount of time to complete. I've been reading more info lately about vray and the common factor is its speed. But I'm not seeing it. My machine is under powered to put it mildly (dual xeon 2.66 procs in HT with 2gb of pc3200 ram..upgrading to 4gb in a few days) but I thought I would bring my case to the experts and see if there are tweaks to be made to my settings that might increase my rendering speed.

Any suggestions that you can offer that may improve the speed of vray would be greatly appreciated. Once things turn around for us business wise I'll be looking to invest in hardware upgrades but until then I have to muscle it out with my current old lady.

 

Thanks

the settings are scene specific , so there is no universal setting , i do feel 100,50 is a overkill , i can get away with 50,30 most of the time,

your secondary bounces can be Lightcache but then it again comes down to the scene , so if theres an image if you are willing to share , then it will be better to suggest some speed improvements

Thank you for the replies, they are very helpful.

 

Maria - I hope the image below gives some insight to what I'm working with. Most of my projects are interiors that focus on office furniture etc. Of course I'd like to understand a lot more how vray's render settings affect time, speed and quality as much as possible but unfortunately as I mentioned I don't use the program that often. I plan on changing that as well.

Benjamin - thats a very interesting plugin and I will look into it and try the demo. I still want to understand the settings etc for myself but this plugin could by me the time to do so.

For a good quality/time combination, I would try:

 

IMAP - Medium Preset Subdivs 40/50

LCACHE- 1000 or 1200 subdivs (Use light cache for glossy rays active)

Image Sampler: Adaptive DMC - subdivs 2/5

 

Other settings depend on if you are doing stills or animations...

 

Don't forget that the world of render times is not only in your F10 key. Reflection glossiness and subdivisions in your materials, shadows subdivs of your lights and other factors affect rendertimes too.
