First off, my system:Athlon XP3200+1024 DDR400 RAM512MB Geforce 7600 GSFirst time i started up FSX it took about 5 minutes before the main screen appeared. I then went to the settings and set everything to around medium high. I set autogen and scenery complexity to normal and switched off the main hoggers (light bloom etc.). I then selected the A321 and set my location to Seattle (to see the worst :) ).On load i found i was getting 10fps sitting on the runway in the VC. I was pleasantly surprised by this. I have heard the stories of people with high end systems getting 4fps etc.I then took off and flew around the surrounding area. It was a little choppy but not too bad. I then tried one of the GA aircraft and sat on the runway in VC mode. I then went to this site (http://www.fox-fam.com/wordpress/?page_id=41) and downloaded the fixes and installed them. I restarted FS and went to Seattle in the A321. I found i was now getting 11fps sitting on the runway (an improvement of 1). In a GA aircraft i was getting 13fps.I took off again. I found even though i was getting 10-11fps it was fairly smooth. Not silky smooth but not as bad as i imagined 10fps to be like. I switched off zone alarm and that saved me 2fps more.Overall i find the sim just about playable when flying the heavies. The scenery is gorgeous and stunning. If you are into bush flying and flying around small airfields you will have the rub of the green. If you want heavies and flying into major airports you will struggle a little with a system like mine. It depends on what your tolerance is.I also changed my anti aliasing/anistopic filtering/screen resolution up/down and found they made little difference to the fps, probably due to to my graphics card being a beast.I set a thunderstorm in Seattle and was presently surprised to find that my frame rates did not dip. I guess the replacement clouds have had some effect :)The only way i was able to get 20fps was by removing the autogen but i cant live with it so i guess i will have to settle for the 10fps i get around the major cities.I also get alot of blurries when flying in the cities and the quality of the autogen and scenery is noticable lower as my system struggles to cope. Fly outside major cities and FS looks and works like a dream.

Im also having a great time now, ive applied all tweak like you and i dont even to bother to look at FPS anymore as it constantly achieves 24 (locked at 24). The biggest one was to lower all the ground textures in size (from that site above also) made a massive difference....The one last problem I have now before I can go off and take some screenshots/make a video is the fact of stutters! Every few secs it seems like a texture file is loading somewhere! goes from blurred to sharp, the ones in the distance. causes an annoying split second paus in sim while it loadsIve got all tweaks applied, and have my fibre frame rate setting at 44, and texture bandwith multi at 80....tried various settings with no difference made to this one last annoying prob!!So one last prob to go and ill shoot a video of an approach into innsbruk with traffic driving along motorway :(IanAMD AM2 3800X21GIG DDRII667mhzRADEON X1600XT 256MB

Sounds great Ian. I didnt do the "lower textures in size" so i guess i should give that one a go.I think we need 2gig of RAM in our machines. When FSX is running, i hit CTRL-ALT-DEL and checked the memory performance and it had been virtually eaten up :)Will try lowering the textures in size and see what that does.

Hi AllHas anybody realised yet you do not need the DVD in drive to use Flt.sim X. Thank you Microsoft,my 2004 disc.has just about had it.I use an AMD 55fx and I am still tinkering with settings, up to about 15 FPS now. I know it's a pain, but we get this all the time with a new Flt.sim. Has anybody flown in england yet, do you see those awfull rectangler buildings all over the place, not very good at all. cheer's Derek.

Did you try the PC-12 autogen fix? It allows adjustments to the maximum trees and/or buildings displayed and is completely configurable from 10-6000 I believe allowing one to adjust autogen to a desired compromise between performance and autogen density. Ian.

Ive used every tweak possible...the sim is running 9/10 now, just the stutters are annoying me!!! .... it seems to be whenever an airport comes into view the sim skips while it loads the textures? if these were lowered wouldnt that solve these issues??? Ive lowered all the ground textures, so I hope someone makes a fix to lower ALL textures to the same effect! Ian

Because I do not experience the pauses you describe.RhettAMD 3700+ (@2.5 ghz), eVGA 7800GT 256 (94.47), ASUS A8N-E, PC Power 510 SLI, 2 GB Corsair XMS 3-3-3-8, WD 250 gig 7200 rpm SATA2, CoolerMaster Praetorian

Those of you with 512 meg video cards probably aren't going to see much improvement by using lower resolution textures. FSX seems to choke very hard when video card is overloaded with textures. 128 meg cards reach this point very quickly. 512 meg cards are probably fine.The issue around cities might be from airport terminals and jetways. The LODs on those models aren't all that great. I've noticed that you can still see the jetways and terminals from 30 miles away. Not good.Matt

Hi All,I got my FSX Deluxe yesterday - i've resisted tweakin under the hood so far, just played with sliders a bit. Biggest gain i got was setting FPS to unlimited (i know there's a trade off somewhere for this but i can't see it yet). It has effectively double my frames and i got to push some sliders a bit further up.As another poster says, flying slower aircraft around some of the beautiful scenery is a winner with FSX. I am absolutely delighted and in awe with the way FSX looks. I'm getting anything from 20-45 FPS in these 'lighter' areas with fair weather and 15% traffic (cars and boats included). I will use FSX like this for the next 6 months and watch the technology develop some more and use FS9 maxed out for instrument flying heavies around cities etc.... RgsEd

For FS9 I cured the microstutters by lowing the global textures down a notch. Maybe give that a go.Ian.

It really really helps if you upgraded to 2 mb ram!

what are your system specs please?
