Hi Filip, There isn't an option built into the OSG that you can just switch on to do the rendering incrementally and provide user feedback. If you want want to dig down into internals of the rendering backend you can implement something like this but it's not trivial, very much an advanced topic that I would not encourage someone new to the OSG todo.
I would add that the vast majority of users of the OSG will be rendering frames at 60Hz+ and very rarely having problems with really low frame rates. If you are having problems with very low framerates then I would suspect that that you are doing something inappropriate with your OSG usage. What this might be I can't say, but I can say it's very very abnormal to have problems like you are describing. So... I would recommend that you focus on working on why your scene is taking so long to render then fix the problems. Robert.
