For those having lag problems in the mission editor here are a few suggestions.
1) Turn your terrain detail to Low (even if it's for the mission editing, you can turn it up later)
2) Go into the flashpoint preferences and in the texture tab change the texture sizes down.
eg:
cockpits and objects from 2048x2048 to 1024x1024
(i don't think any addon makers are using 2048 texture sizes so you should notice no difference)
landscape to 512x512
(as above I dont think any addon maker islands are using texures larger than 512x512)
This should help in the mission editor. Don't forget that Tonal is a 512x512 island meaning it has 262,144 land points that need to be calculated as opposed to the Nogova 256x256 (65536 land points)
Adjust figures depending on your specs (the above work fine on a AMD2100 ,512 RAM, GFTi4200 64meg
