Hi Julen, It sounds like you have a single View but with two slave cameras, once slave for each window. This would mean two graphics context which will mean a performance and memory overhead. Sharing contexts would help on the memory consumption front, but it'd only be safe to run the view single threaded otherwise the OpenGL objects could get corrupted.
