Memory usage in a LibraCad drawing

If a LibreCad document drawing uses lots of layers are they stored in the graphics card memory or the computer memory? Does LibreCad use much of the graphics card memory or swap in and out with the main computer memory?

I am having to change my card and have a limited choice which come down to a choice of a 2GB or 4GB card. The latter is much more expensive but apart from more memory has features that I do not need. Logic says buy the 4GB card for the memory but why waste money on features I do not need.

Many thanks for the clarification. It is very helpful.

2D usage of GPU does not require large video memory or fast GPU at all. I found no graphic performance issue playing LC on intel integrated cards with 256MB or 512MB shared video memory.

As for system memory, current Text implementation in LC consumes lots of memory and CPU. Try to get a system with fast CPU and large system memory(RAM). LC does run well on low end systems, as far as text/image usage is light.

actually, I keep switch

runs fine at
