Hi Tobias, What graphics board and what driver revision ?
Do you know what threading model you have selected ? If its standard osg viewer try running with --SingleThreaded option and see if it helps. I was investigating some Windows / NVidia / multi-monitor / multi-threading problems recently and observations are rather sad. I was unable to get it to work without either setting OSG to SingleThreading, switching off one monitor or turning off one core on the CPU. So it looks like mutimonitor/multithreading issues in the OpenGL drivers. Do you still have OSG 2.0 can you check what mutlithreading option is selected ? If its not SingleThreaded then it might be interesting because it may mean that some changes in OSG trigger these probles somehow.

Using OSG 2.0 there isnt any problem. Using OSG 2.2 to compile the project, the second output window suffers from enormous performance loss and produces only small framerates (>1fps). When I minimize the first window, the second window runs with full performance. I think it is a thread-management-problem in windows XP (SP2) based on specific settings in OSG 2.2. Does anybody know a solution?
