I tried to see if the reduced trees and clouds textures would still raise my fps after installing SP1. To my amazement installing the reduced textures even lowered my fps! Okay, it was just 1 or 2 fps, but in an environment were I got about 10 to 12 fps (with very high settings) I got 9-10 with the reduced textures!This might of course be due to something in my setup, but before people with not to good systems start to install these reduced textures, be sure to backup the original textures before you do so becaus there might be a change you will have to go back to the original ones!All in all everything is VERY FINE over here! In the places where I usually fly (Norway, Switserland, so lots of trees, mountains and a few small cities) I get a constant fps above the 20 with a few higher settings than I used to use. I now got autogen and scenery objects at extremely dense: wow, what a detail!!! It looks so real!!! Awesome! (For people who don't like autogen: don't forget that the more you use, the better it looks!) I can even fly around KLAX and La Guardia without dropping under 10 fps! With autogen etc. at extremely! And the textures on the airfieldbuildings don't disappear anymore like they used to (makeing everything look grey). When I look around after taking off, I see everything the way it should be. Very nice! :) Before SP1 everything slowed down to 5 to 7 fps and it got choppier and choppier... But now I can even look around with my Track IR without a big drop in fps. AWESOME!To end this all, for anyone who is interested, here are my specs and settings:- I got a E6600 with a 8800GTX and 2 Gb Ram, Vista Home Premium - FSAA is at 8x in the Nvidia driver panel- I set visibility to 10/16 in the weathermenu, which also saves some fpshttp://i16.tinypic.com/53fbzva.jpghttp://i5.tinypic.com/549w111.jpghttp://i19.tinypic.com/4mlz1x0.jpghttp://i11.tinypic.com/6f9upg8.jpghttp://i10.tinypic.com/4xz6nox.jpg

Some things which might help your FPS a bit.First save your settings so you can reset them in a few seconds.Move water effects up to Low 2.x - this adds reflections to water and helps avoid a flat look by adding a tint of blue from the sky reflection.Set the Mesh Resolution to 10M unless you actually have some mesh better than 10M. That's the best I've seen so far.Move the Autogen down to DenseMove the Clouds down to one knotchLeave the Scenery Density slider on the maximum setting - it's very important to keep the airport Jetways.

Needs Vista and Quad support, in the hangar until de DX10 update... another 6 months aproximately stopped the simulator, love FS2004 meanwhile.

I would change ground scenery shadows for medium 2x water settings or light bloom. Those two are way more noticable (graphiccally) for the same performance in my opinion.

To my amazement installing the reduced textures even lowered my fps!I did the same thing (TreeX v2, reduced clouds) in my SP1 installation, and I noticed further improvement over the "stock" SP1 install. As always, *back up* your originals before applying any tweaked files (I did just in case), but in my case, the slightly lower res trees and lower res clouds futher improved my experience with minimal visual quality loss.
