Sorry, just need to clarify some things...
1) Should I put the fs2_open_3_6_9.exe in Wing Commander Saga and Babylon Project, then select them in the launcher to improve performance?
2) How do I get that same launcher to run for normal Freespace 2 so I can choose the fs2_open_3_6_9.exe? Or, is it as easy as just putting that file in the Freespace 2 folder and somehow it just works off the best one?
3) Is fred2_open_3_6_9.exe superior to normal FRED? If so, should I therefore put them in the Freespace 2 folder as well as the two stand-alone-games and work out of those to produce better quality missions? (NOTE: Minus some HTML error I am able to byepass, the FRED utility DOES work for Wing Commander Saga...thanks again Starman1

)
4) How does 3.6.9 help things along?
Sorry about all the questions

Hope I'm not causing trouble.
