video cards
Mar 14th, 2009, 2:59pm  
I have a quadro 4600 at work and I have a 4 year old nvidia card with 128mb on my laptop.  I have been making a particle system project and importing the open gl library in the "sketch".  I have noticed that my old laptop card is faster than my one year old high end workstation card!

The next time I buy a laptop it will be for doing live VJing type work.  Is a gaming card going to seriously out perform a workstation card in Processing?

I have been doing 3d work for the last 6 years and this issue still alludes me.

I thought there were no such things as stupid questions Sad

The question isn't stupid, I suppose we lack useful data to answer.
But sure, if I buy a cheap computer with on-board integrated generic graphics chip today, it might very well be outperformed by an old computer holding a state-of-art (at the time of computer buying) graphics card aimed at gaming.

I would have said the same thing, integrated graphic cards are really slow, even an AGP card beat them (that was the case of my previous PC).

But maybe you get the same bug as me if your workstation is running on a dual screen setup (see my post http://processing.org/discourse/yabb_beta/YaBB.cgi?board=OpenGL;action=display;num=1235056546), where the OpenGL sketches actually run at half the speed they should be running.

Additional note: my work discarded old computer and as they are allowed now in France, they gave them to employees wanting them.
So I got at 5 years old computer, which was much better than the 10+ years old I had at home... Smiley
It has a Nvidia GeForce4 MX 4000.
I found an interesting Java application (JGears) making an intensive usage of various 2D graphics features.
I found out that I was running on standard Microsoft driver. After upgrade to the latest Nvidia driver, it was 50% faster!
