I set these way and worked well sometimes still dropping fps but was in a first try I will try some other changes latter.
I'm trying to not lose my head with these thing but if the game runs ok it's fine.
Like the guy said before DCS 2 is almost here, and I want to do some upgrades on my pc and than will see.
Latter I do some other changes an see how will work and post here.
Thanks a lot guys.
