I am looking into the Multiple Draw Buffers (or MRTs in DirectX terms) issues in Opengl. But I found there is problem when I try to increase the buffer size over some threshold around 2048x2048 (and have totally 4 rendering targets ). I would like to know if there is any specification about this ? Thanks to all OGL guru here :)

When using frame buffer objects you can query MAX_RENDERBUFFER_SIZE_EXT for the maximum size supported.
When rendering to texture I assume the maximum texture size is the limit.
