autogen tweaks, curious.

Folks,First of all, I'm new here, so hello to you all.I'm pretty new to tweaking FSX.I was using FS2004 for quite a while and then tried FSX and ended up building a new computer to run FSX. My wife and kids call it "The Monster", but with FSX it's not so much a monster after all ;)Anyway, I found this autogen tweak here:http://forums.avsim.net/dcboard.php?az=sho...=&topic_page=12The one by Matt Fox for trees and roofs.I also found something for smaller textures for autogen buildings.Now, I was getting my hopes up... I noticed that no matter where I looked, the file was missing for download.I saw a message that NickN posted that said those tweaks should no longer be used with SP2. I pretty much take anything NickN says to heart so, ok, understood. I can't use it for SP2.My question is, just from curiousity is, why shouldn't we use those particular tweaks with SP2. Did the devs implement those tweaks in SP2? Or is it that using them will break something? If someone could clarify, that would be great.Also, the reduced textures for autogen buildings that I found, is that also not to be used with SP2?Cheers and thanks,Teddie
