New tweak suggested by Nick Needam - External FPS limiter
I bumped into this while looking for news of GEX Europe. It seems it has helped a few people with stutters. I intend to try it but haven't got round to it yet. It seems that Nick is endorsing it so it must be good:
It seems to be an external FPS limiter that works better than the internal one. The internal slider must be set to unlimited. I must admit that in my Quad I get much better FPS when I set the FPS to unlimited ingame but I do get stutters so this might be the answer. I'll try it and let you know the results.

Thanks..This was previiously been discussed before....
If you get stutters with your frames unlimited thats usually the cause...
Try setting your Texture_Bandwidth_Multiplier to 90...Thats what I use
Also try 40-50-60-70-80-90-
Lock your frames too...Mine are locked at 60
Running unlocked frames is basically telling FSX ....Hey, see that town out there, yes, that one, 90 miles away, you can't see it for 80 more miles but draw it anyway..... Hence the stutters....
I get 60 frames almost solid (except large airports, I have traffic at 50%) and no stutters at all..Very smooth.....On a E8600 duo....

We have indeed discussed locking frames before and my observation, which is btw similar to some other users of quads, was that setting the frames to unlimited increased my FPS from an average of 10-15 to an average of 25. I know it does not make much sense but this is how it was on my system. Locking the frames only throttled it for some reason. Unlocking, unleashed it. I do use the Texture_Bandwidth_Multiplier entry too.
Now this external program might take care of some internal MS issue that is causing it. Nick specifically reccomends it to i7 people in particular. Might be the same issue with quads. I'll let you know how it goes.

Please report back your findings.....
But remember.... If locked frames only gives you 10-15 are they smooth frames? that is the question......
BTW Do you use the Job Scheduler tweak Dimus?

Yes I do use the Jobshceduler and it helps indeed.
I just saw in Nick's thread that this does not work with DX10 and this is what I use. Any of you using DX9 (and it is most of the people here I understand) may try this. It does not seem to work for all. I'll just stay as I am for the moment. My recent OC seems to be the best tweak I've done so far.:d

If I run unlimited in FSX I get an average of 30fps or so depending on where I am, with drastic swings and spikes occurring now and then which causes some stutter. If I try to fix this by locking at say 30, I end up with a true fps in the mid 20's or so... below what I set it at. Seems I can have higher fps with unlimited, but get stutter from the frame rate spikes or lower fps with less stutter while locking via FSX. Even if I lock to 99 I end up with these locked, but lower frame rates.
With this external limiter (which I've been using for a few days now) I can get the benefits of running unlimited in FSX, and a real proper frame rate lock at or around whatever I set the app at. If I set it to lock me at 30 I'll see frames in the 30 to 35 range, but no higher while not having to deal with the lower frame rates that framelock in FSX gives me.
It seems like this limiter works the way the one built into FSX should work, but trimming off the high fps spikes and yet not reducing your overall frame rate downwards. It's a simple run once to create a batch file, then never think about it again... at least for me.

I'll have to give this a try as well.

It's one of those "you have nothing to lose" type things.

Well... I didn't like it. Using the FSX limiter at 24 my system holds 23-24 and smooth unless using a FS9 aircraft and/or flying in a graphics intensive area, then my fps drops to 18-20, but still smooth. The external limiter (with the FSX limiter set to unlimited) set to 24 or 30 gives me 30 to 35 fps with routine dips to 17 and seems to increase the stuttering. Leave it to me to throw a wrench into the works!

To kill the stuttering raise your Texture_bandwidth_Multiplier to 70-90
