Hello Robert and Jason, Thanks for the fast response. I didn't want to create my own render loop as I thought I read somewhere that the rendering could be multithreaded (the const part of the culling could overlap the rendering phase for example). But I guess that this happens within the call to viewer.frame(). So creating my own implementation should be fine.
Btw. I can't find the page explaining this anymore. Was I dreaming?
