Laggy computer.

[*Delete]

Whilst rendering enclosed scenes for a current lighting project (with only a couple of simple materials & Light sources) my computer interface becomes amazingly laggy.........this I believe is because I am a fool & dont have a seperate GPU - instead I'm relyin upon the integrated HDgraphics in my i7 2600K CPU.

Therefore, I am wondering what GPU is going to best to accompany VRay for RHino
I was considering a Quadro 2000.....but would appreciate some advise on whether this is the best route - (please note that I do absolutely no gaming on this system - merely Rhino, Adobe Photoshop&Illustrator etc).



I'm sorry for bringing this age old debate back up, but I'm amazingly bad when it comes to PC Hardware & just cannot find a definitive answer.
Cheers.

V-Ray for Rhino does not currently use the GPU so it will make no difference. How much RAM do you have? Are you running a lot of stuff in the background? OS? All that good stuff.

I thought this might be the case with Vray - was a while since I did research into Vray, so all the info has dribbled out my ears.
Currently have 8GB hooked up (on Win7 btw & its only a 5month old PC)

This is the thing, I wasn't doing anything in the background for the simple fact that I couldn't - it was laggy with simply Vray+Rhino - (this is not useful since as a student as I need to beable to get on with Photoshop etc)

I use Vray at XP64 since years and have no problem to work on my machine during a rendering is running. Did you enable low priority at the Vray options?

Indeed, I did enable low priority to minimize the impact Vray has upon other programs - had been following the supplied Vray manual since I am somewhat new to this software.
This is somewhat baffling since it was a small enclosed scene & of a low res output.
The issue seems to rear up randomly (sods law right when I have a close deadline) as vray normally behaves absolutely fine the majority of the time

I would buy a seperate GPU, something like a GTX 260 ... 295 should do a good job. I would try to get a card with much memory for many highres textures at the rendered viewport.
