Hello guys,as soon as I activate scenery (even at minimal settings) FSX starts stuttering and boring me. I run up to 120 frames per second (40 in big urban areas like NY) and i tried everything i could to fix this problem but nothing...My specs:Alienware M18X2720QM Sandy Bridge I7 CPU 3.3GHz (8 threads)8GB 1600MHz RAM2x6970M ATI Crossfire graphic cardsMomentus XT Hybrid SSD Hard DriveWindows 7 Home PremiumNo AddonsNo extra gaming hardwareIf anyone can help it would be much appreciated, thanks

Try locking your FPS at around 28 to 30 and it will probably smooth you out. There is also an external FPS limiter that some use, but you could try locking it in FSX first to see if it helps before you venture into using the external FPS limiter.

Your rig is a nice one. I'm sure it runs your other games just fine. There isn't a rig out there that can run FSX maxed with addons(which you don't have). And everyone has their own formula for making FSX work.FSP means almost nothing in FSX. So yes, try limiting your frames. Some folks run different frame rates depending on where and what they are flying.FSX gains nothing from crossfire.Turn down water to low 2 or high 1Turn down air traffic to 50% or so.Turn down cloud draw distance.If you know what the fsx cfg file is you might try deleating it and restart the sim.You might look into the many tweaking guides that are out there.Good luck.Bob

Normaly, you get smooth flight when lock fps to 40 or below, try with or without external limiter.

Try the affinityMask setting that helped me and a lot of other who had stutters. 14 will use cores 1, 2 & 3 and leave core 0 to run windows and background processes. Has a greater impact for some than others. Also turn off hyperthreading.I I found road trafic also had an impact - try turning that off and see what happens.Do you still get stutters if you turn down your graphics setting by one knotch accross the board?This can also occur if your videocard settings are too high - no more than 8x AA and 16x AF is needed.To get the best from fsx, you would need to overclock that Sandybridge. It should go well over 4GHz if you have decent cooling. Ive read reports of over 4.7 GHz if you have cooling and are brave enough.If that don't work, then go over to Simaviation FSX formu and read NickNs guides on how to set up your system to run fsx properly.IAN

Stuttering is a problem in FSX that is real tricky to find the cause for. I notice quite often that after having installed FSX and addons that after a while stuttering starts to appear. Funnily enough all the great suggestions to turn down the settings dont really help as I find that I get stuttering in turns even with all the graphics settings turned down to zero... which points to a hardware situation or a driver situation or a windows 7 OS issue.I am about to do a clean install even of the OS as my stuttering FSX (even locked at 30fps) is bothering me and it used to be silky smooth...I am using a Sandy Bridge 2500K at 4.7Ghz, 8GB Corsair Ram + GTX570 so I have plenty of horsepower.....Any suggestions would be great...Hamish

Hamish, maybe a defrag would cure the problem?

CarloYou might try turning off Hyperthreading in the BIOS (2720QM Sandy Bridge I7 CPU 3.3GHz (8 threads)) it looks like you have it activated and that can lead to thread collisions and hence - stuttering!RegardsPeter

Bojote's tweaks? See my sig...AND - Torkermax is right, moving as many fsx-related utilities off to a networked computer is the key.
