I could suggest trying Tachyon, if you want something faster.
However you've got some problems with that:
1. Tach is every bit as old as FS2, except it never had any improvements.
2. Single player is too easy, multiplayer is where you would have gone.
3. NovaLogic just eliminated running servers, for MP, so there's no where to go
unless you hook up with someone direct. One fan has asked they be restored,
no response yet.
4. Once FringeSpace get's back up to speed again, then you've got
that as a far better replacement.
So yes, you want faster dogfights, modify your tables. You'll also need
to adjust the weapons, as we found out earlier too.
