Hi all,

thanks Björn for the MSAA pointer - it was not the cause of the issue but
the explanation on the 75Hz helped me solve the problem:
I had to remove the V-sync setting from the driver configuration.

Works like a charm now :)

So to keep a smooth experience the osg application must be able to render
at 75Hz for both eyes - is that correct?
This is an important tip to keep in mind...

I also have some questions about post-process but I'll switch to a
different thread.
Thanks again!
Ricky
