What ways are there to reduce vram (GPU memory) usage in blender? I am rendering a scene and it's taking a lot of GPU memory. I have a 2GB card. What are some methods? i am pretty sure this has been asked before, but i didn't get the answer i needed.

The 2 main things that'll take up video mem are gonna be:
how big are your textures, and how many vertices are in your scene.

Use the decimate modifier on your models effectively.
Try out scene simplify. I'm certain you can look those up for more info.
