My goodness, news to me. Are you talking about 1.0.0? FG 1.0.0 is based on plib. No involvement of OSG whatsoever. None. And Simgear doesn't select plib/OSG by itself. Even when you use cvs-HEAD (NOT version 1.0.0) Simgear needs BOTH plib and OSG. You will probably find the Version 1.0.0 runs a bit faster than 0.9.10. OSG (NOT version 1.0.0) is significantly slower. HTH Vivian ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
