:-lolMe Too... I can taste it now :9:-beerchugLee

But even with EVERYTHING off, fps is max 12 with autogen at Dense... Turning of 2x water has no effect at all.

You can fix this yourself with FSX KML... very easy to do.Here's how1. Run Google Earth, and locate your airport2. Draw a polygon in front of the runway where you want to "cut down" your trees.3. Save your KML file4. Make sure FSX is closed5. Run FSX KML and open your KML FILE (click ADD KML)6. Tag your polygon with a landclass that has no trees, eg LandClassPoly_Grass.7. Click build, the scenery file will be created and copied to your addon scenery directory8. Run FSX and hey presto! You should have grass in front of the runway and not trees. NB: You need to have the FSX SDK installed.See my sig below for download instructions. FSX KML is available in the AVSIM libray.

I noticed that on 1x water things are much faster with lot of autogen.When you say shadows, do you mean aircraft shadow or just ground object shadows?

>I think I will start the weekend early and by tonight, my>world my be a little blurry>>:-bla I started the weekend hours ago with a few margaritas...X-PLANE FOREVER!!!! :-hah

Hi Matthew.Turn off all shadows, otherwise another rendering pass will occur.I cannot believe someone with a high-end machine would have any problems with a stock FSX after SP1. Maybe addons are messing with the sim, or something is wrong with the computer, or the FSX.cfg file is messed up ( or bloom, shadows, or 2x water is still on ).I fly Chicago with autogen full on, and 15% air traffic with a solid 26 FPS. No bloom, no shadows, 1x high water, 10% road traffic, and 10% for the boats.Core2duo 6300 with 2GB memory... nothing fancy.Dick

There seems to be a problem with trees in SP-1. I can fly over San Diego with max scenery complexity and extremly dense autogen with about 25 fps average. The same for LA fps drop to 20fps. I go to Lake Tahoe and fps drop to around 12 to 15 with horrible stuttering that I cant fix at all. RTM used to hit fps in the cities bad but in the mountains is was much better. And for those whos say you need 3 or 4 seperate configs one for each variety of terrain WTH?? Lets say I fly from LA to Lake Tahoe, the same config that gives relativly smooth performance over dense urban terrain goes to a stuttering mess once over dense forrested terrain which kind of defeats the purpose of my flight. When I was using St.Maarten as a test area I noticed how now buildings are first priority in terrain rendering followed by trees then max ground textures (which is probably why blurries are happening). I am leaving FSX alone for awhile now (too many hours trying to tweak this sim has gotten on my nerves)

But I've got a E6600, 2 Gb Ram and 8800GTX and setting autogen to anything higher than Normal limits fps to 10-12... regardless off other settings.

Glad (not really though) to hear someone else has the EXACT same problem: good fps above cities, low fps above mountains. Up to now only one other person said he had the same problem. May I ask what your config is? CPU, RAM, graphics card, OS? There MUST be something wrong somewhere in 'our' setups...I also have only been tweaking and testing ever since SP1 once released. It does get very annoying, but I just want FSX to WORK!

Looks like you are the perfect candidate for the trees per cell tweak. I have my autogen at very dense with reduced trees and it still looks very nice. Lots of buildings around and it runs very smooth. Just experiment with different values f.e.:{TERRAIN}TERRAIN_MAX_AUTOGEN_TREES_PER_CELL=800then work your way further up (1000, 1200,...) until you find a good compromise.Just an idea and worth a try.Heiko

Hi J.Could you include a zipped FLT file so we could try the flight to check the same thing on our computers? If possible, also include a saved CFG file from your display menu.Attached is a Chicago FLT and the saved CFG.Dick

Okay, here's a cfg with EVERYTHING off (called Alloff.cfg) and only the autogen at Extremely dense. Also included is the flight I use for testing (Trees test.flt). As soon as it's loaded I look down to the left where all the trees are. I included two screenshots, one looking in that specific direction and one looking straight ahead (yes, that's how FS X looks with everything off! ;) ) As you can see on the screenshot looking down and left, fps is 11.x: it hovers between 8 and 12 while flying. With everything else off. I'm really curious what results others will get!http://forums.avsim.net/user_files/172477.zipP.S. The zip was too large with the images, so now it only contains the flt and cfg files: here are the images:Looking left and down:http://i13.tinypic.com/6f7zat4.jpgLooking straight ahead:http://i14.tinypic.com/543m839.jpg

Hi J.I ran the flight with and without your CFG settings. Not really much difference! And, yes, the FPS are surprisingly low. I am getting around 14FPS at the worst views, and about 25FPS at the best ( as you have the target setting at 25 ). The worst views seem to be either right or left.As the flight progresses, all views eventually rise to 25FPS... and when set to unlimited, I eventually get a low of 25 and highs in the 80s ( where my refresh rate is set to 85 ). Near the snow-capped mountains, I get even better FPS.There are 3 factors I can see.1) The virtual cockpit presents more GPU and CPU load.2) Using the 50% zoom level of your flight will lower FPS, as more autogen are vithin the viewport. This is true of FS2004 and FS2002 as well.3) This forested area has several utility corridors... and I suspect they may actually be the worst offenders. As the flight progresses away from the utility paths, the FPS significantly rises.I'll play with it a bit, and see if eliminating the utility corridors, or altering them is the key.Dick

Hi J.What I did was to disable all the scenery elements by renaming all the #4910 files in the 0610 folder...this gets rid of all scenery other than autogen and mesh ( even no water ).The result?The trees still bring down the FPS significantly, even if the zoom is 100%.The only cure is to reduce the autogen settings down to Dense or lower to restore the FPS. Essentially, just what you've stated.However, I'm still getting better FPS than your system. I get a low of no less than 14FPS with a 6300 Core2Duo and 2 GB of memory with a Nvidia 7900 GTO ( 512 MB ). Most views are getting 20+ FPS. There is something that is dragging your system. My system is stock FSX SP1 with only a joystick attached. No addons or special hardware.I can get decent FPS ( 23 for a low ) with a Dense setting for autogen. You apparently need Normal, with a much faster system. So now we're back to the idea that you are using Vista, or you have background processes interfering, or your FSX setup is not stock, or has extra hardware dragging the system.But, yes. The trees are causing a slowdown in the FLT you have attached. And a TERRAIN_MAX_AUTOGEN_TREES_PER_CELL=2000 setting isn't really helping... the density slider needs to be turned down. I would suspect this is could be a problem when flying over forested areas. Phillip Taylor suggested having several CFG settings for different flight areas in a recent blog, and I thnk that is good advice.My only question is: how much more CPU / GPU/ Memory would it take to resolve FPS difficulties in forested areas? And is it the number of trees, or is it the MDL of the autogen?Dick
