Gigabyte on graphics cards important for Lumion?

Hi,
I have an ATI HD 6970 with 2GB.
Because of my 3d-package c4d has massive problems with ATI I´m going to buy a nVidia card.

Question: The more GB a card has the faster does is render? So - should I buy a 4GB card like the 4096MB Palit GeForce GTX 680 JetStream Aktiv PCIe 3.0 x16 for example?
Or any other suggestions which card?

The GTX 680 with 4GB RAM is probably an optimal card for Lumion at the moment.

More on-board RAM means that you can create bigger and more complex scenes with lots of materials.

Morten,
how long is the render time in % per frame comparing a 2 gb and a 4 gb graphics card?
I guess that you guys have several  work stations with different graphics cards...

No, we haven't got any benchmarks.

More on-board RAM means that you can create bigger and more complex scenes with lots of materials.

If your scene uses more memory than your graphics card and system memory provide (in Windows 64-bit), there is a greater risk of graphical glitches. In addition, Lumion will then be forced to use the pagefile on your harddrive as swap space and this will increase the render times significantly.

So if you are planning on rendering very complex scenes with lots of different models/materials/textures, you should buy a graphics card with as much on-board RAM as possible.

OK - I understood.
But I guess if the 4 gb is 10% faster than the 2 gb than it  does not make sense to spend that money for the bigger one.

I have a GTX580 3Gb - 24GbRAM.
Often I use more than 10Gb of RAM and 10Gb HD Lumion.

Hi all

It will be good if there is a way for us to submit our render times for standardised test scenes based on the OS/Memory/GPU/CPU used.

Maxwell Render had that function for users to submit their render times and enable us to figure which setup works.

Hi azazazaz, you're absolutely right - a benchmark scene in Lumion (or even a separate benchmark application) would make it easier to figure out what kind of performance you can expect from a given hardware configuration.
