Hi Robert, Another observation I forgot to mention:
In a test involving only two screens, the left screen being 1680x1050 and the right screen being 1280x1024, I noticed that the image on the right screen does not have the right aspect ratio. The best way to see this is to try the osglauncher example.

I did some testing yesterday evening on Windows and here are my results: { Platform: Athlon X2 4200+, 2GB RAM, Windows XP latest patches, NVIDIA GF7900GT & low-end NVIDIA 6150, 3 screens } Running runexamples.bat for each threading model Single-Threaded =============== osgimpostor (extremely slow) osgplanets (corrupted image on center & right screens - left screen OK) - will double check my setup all other examples perform well CullDrawThreadPerContext ======================== osgprecipitations (slow) crashes for: osgdistortion osgdepthshadow osgimpostor osgprerender osgprerendercubemap osgshadowtexture osgsimulation DrawThreadPerContext ==================== osgprecipitations (slow) update processing seems to be out-of-sync (very fast movements when mouse is used) No smoke/fire effects visible for: (probably due to issue above) osgblendequation osgmultitexture crashes for: osgdistortion osgdepthshadow osgimpostor osgprerender osgprerendercubemap osgshadowtexture osgsimulation osgpick osgspheresegment CullThreadPerCameraDrawThreadPerContext ======================================= osgprecipitations (slow) update processing normal but performance generally sluggish on all examples crashes for: osgdistortion osgdepthshadow osgimpostor osgprerender osgprerendercubemap osgshadowtexture osgsimulation osgpick osgfxbrowser I will try to look at some of these issues this evening.
