Iray Painfully Sluggish

Daveman

I fired up the Beta 4.8 and tried following a really AWESOME tutorial on YouTube by SickleYield
https://youtu.be/L5FZ5gS9v50
But wow! WHen I turned on the IRay - things ghosted, nothing appeared like hers at all - and every tab and setting I clicked I made was taking forever to change on screen.

Could it be my system?
Windows 7 (64bit)
AMD Athlon II 3.0 dual core
2GBs DDR system ram
Nvidia GeForce GT 630 (1gb dedicated v-ram)

DAZ 4.7 does as well as I can expect., but the 4.8 beta everything is just odd - at times it's almost like working with Reality 4/Lux Render - then things go wierd with every adjustment I make to the scene - taking forever to respond.
Thanks for any help or suggestions. Im on a SUPER Low Budget and cant afford a gaming monster machine. Whats the most MINIMAL changes i need to make on my system? Or is my settings wrong?

I would imagine that your GPU is not powerful enough to cope with rendering with iRAY and at the same time updating your screen. Your system specs are very low. For example 2GB of system RAM is the absolute minimum for running Win7 x64. If you can, upgrade your RAM and GPU and I think you'll notice a difference.

Try updating your drivers to the latest one...from Nvidia.

Thanks. Yeah I may opt to switch to my other computer (one I built myself) - which has 4GBs ram and dual core - and replace its Radeon with a Nvidia GPU. Im guessing iRay will not work well with my 2GB Radeon GPU. Just my luck :-)
The better GPUs are so darn expensive. I may have to save up for a really good one. OR gradually build a newer FX computer system. By the time I get all the parts iRay will probably be outdated - LOL

My main computer is an older model, which I upgraded from a single to dual core and 2GBs ram is about the maximum that particular motherboard will handle. Anyway - thank you again.

I didnt think about that. I'll check and see if there's a newer driver for it.
Thank you for your assist.

You could also check the settings for OpenGl in the prefecerences-interface-menu. I would recommend switching Anti-Aliasing off and Texture Resources to performance. Also Display Optimization to best. That should help a bit.

IRay does not take advantage of a GPU on any AMD/ATI or older Nvidia graphic cards.

Thanx - I havent turned the anti-liasing off (yet, but may end up doing so) but my work around which helps some is using the Texture in the Viewport when constructing the scene instead of the Iray view which was in itself a horrible experience. I have some programs running in the background that I cant track down and eating the heck out of my system ram! Im talking like 80 to 90% of my ram! I tried tracking it down and closing some start up programs., and cant find anything to account for the massive memory use! I ran MalwareBytes and still came up with zip.
Increasing my Virtual Ram to just under 1GB helped take the edge off enough to make my first Iray render. It took forever but doesnt look too bad, considering I ended up using a preset scene and the standard lighting that came with it. I posted it in the gallery..., http://www.daz3d.com/gallery/#images/61733/

My Nvidia 1GB DDR2 graphics card I installed it about a year or 2 ago - but still I'll probably end up ordering 2GB Nvidia card - something in my limited budget of course.
