RT are heavy and limited resources and one as to be careful with them.

This is what I wanted to know. Thanks!

RenderTexture internally creates an OpenGL context, which uses a significant amount of RAM.

Thanks!

Do you already have something running or even run into performance issues, or are you just paranoid about memory usage?

After creating a few hundred RenderTextures, the program hangs (when I run out of memory).

How do you measure the memory usage and specially the change?
Besides the RenderTexture is allocated on the GPU, so are you checking the GPU memory?

I'm creating a new RenderTexture every second and calling create(), and checking the memory in windows task manager. How would I go about checking the GPU memory?

Graphics / [SFML 2.0] RenderTexture memory usage

When I create a RenderTexture and call create(40, 40), it uses about 4 mb of memory. Is this normal?
