stutter on landing solved!

Recommended Posts

As I posted earlier, it's not about the effects (except we do know that runway skid effect file in fsx/effects must go away) for the PMDG jet, I noticed my touchdown pause was caused when having any form of fiber_time_fraction=## in my fsx.cfg. Getting rid of the fiber_time_fraction command solved the touchdown stutters !! I know it makes no sense (or does it ?) .... but it does work, try it if you're having the same slight pause on touchdown! FTF command seems to do nothing anyways in my ******* tweaked .cfg.. I am not sure why I was so anxious to put it in again...

I think Peter, that FTF is pre-SP2, and is not required. There is a couple of other tweaks that ******* tweak guide puts in that are also pre sp2, cannot remeber which they are now, but some tweaks can have a negative effect.

Peter do you have frame rate locked internally in FSX? My understanding is that FTF only comes in to play when you have frames internally locked. I run FSX in UNLIMITED mode using an external limiter, in which case FTF has no relevance. Even so, it sounds suspiciously like a red herring that FSX so commonly produces. Noel

Noel, FIBER FRAME TIME FRACTION - With ANY multicore processor AFTER SP1 USELESS WITH TEXTURES However this can be used with systems that run TILE PROXY http://www.simforums...D=170479#170479 [sCENERY]SmallPartRejectRadius=x AFTER SP1 TOTALLY USELESS<<<<<Another ******* tweak

"Totally useless" is not accurate - what Phil Taylor said is that it probably won't work on batched objects - not all objects in the sim are batched. The command was actually added in SP1 - it's SP2 that does the batching stuff.

I have finally solved all stutters, landing or otherwise!simple: use NO tweaks at all... let fsx rebuild its .cfg and go from there!! Sharper textures, LESS framerate than with tweaks.. yes, that's right, but not much but way more steady without pauses and surges... and NGX will run way better than you've ever seen!

Very interesting. Guess it can't hurt to try for a flight. To be clear though, did you meen higher or lower framerates?Also assume Highmemfix is still required?Regards,

For myself I have noticed, that NO TWEAKS at all is also the best way to run FSX. Only things to apply - highmemfix and widescreen + 4096 thing. All other tweaks lead me to the stutters or blurries. :( Ok, maybe it's just my own "curved arms". Yes I am using external FPS locker, internally set to unlimited.Running on Quadcore@2.9 GHz, 8gigs, GTX270 win7 64bit.

I don't recommend using this tweak if you want to see traffic or your buddies in multiplayer from far away.

yes, frame rates are boosted slightly by all the tweaks (like *******' etc.) yet, they cost you a price in stutters, pauses and jerks... I do run antilag however, and keep FR at 30... and I am using PMDG ngx with the low res VC gauges, on my good laptop, it runs so smooth and still looks great

Hey, i know what you mean i am getting a small stutters, sometimes for about 10 seconds, i dont know why so annoying, i have started a topic about it, seems that no one could help me, i have done this: http://www.venetubo.com/fsx.htmlis it the cause to the stutters? if so how can i repair it? also my resolution is on high, is that matters?, Daniel, regards

That doesnt work for me. I got a highly tweaked cfg and my experience is completely smooth and stutter free, with next to no blurries and generally awesome visuals. If I run a default cfg i'm getting horrible stuttering, horrible blurries and a way way lower framerate. YMMV

I got about one million tweaks, far to many to mention here. Have a look at nickn and bojotes guides. Dont just blindly apply every tweak tho, its critical that you understand what a tweak does and how it will respond to your system before you apply it. Remember that every system is different and require different tweaks. The by far most important tweak for me was UsePools=0 combined with the internal framerate limiter at 29 fps

HEY, thanks!, where can i find these guides?

Any tweek that might be causing FSX to freeze? I've been getting freezes since upgrading to service pack 1. Using Bjote's tweeks. I've had the suggestion that I should back off my overclock to see if that is the problem. Haven't gotten around to it yet. Cleaned my fans and heatsink and still had a freeze on my next flight. Never had a freeze before SP1. Very frustrating. Can't understand how my overclock could suddenly become unstable after 6 months of flying...

I'm trying different tweaks at the moment (including ******* ones) with my aging PC (C2D E8600 @ 4,2GHz, Nvidia 9800GTX+ running the latest drivers, 4GB RAM, Win7 64bit) and to be honest I cannot see any improvement so far :-( I was expecting "wonders" using external fps limiter and online *******'s tweaker and saw no really any improvement so far. Still NGX is very flyable with 30+ fps in not very demanding sceneries but on some airports I have ~10fps which is quite frustrating (but then I remove AI traffic and is fine again).I think I will start over with a clean fsx.cfg again as Peter has sugested. :-) Gregor Gresiaczynski

Over 4 months of testing with all the tweaks out there, I found out yes you can get slightly better FPS performance, yet at a cost... added stutters, weird pauses that occur in random locals... not related to defragging etc..... it was all the tweaks.....once I rebuilt fsx.cfg the "natural way" and just ran the NGX on fsx ... with no tweaks at all...none, nada, except for custom shift-z stuff, autogen trees fix and the TBM brought to 80, that's it!and you know what, for ME (not everyone here certainly), but for me it was back to stutter free, lower frame rate variability (the tweaks really added variability and the external lockers too did that) ... and things are so much nicer... yes, the FR is less (I use the FSX limiter built in the menu) .. but it is steadier!!Try less, it really is more, you may be surprised ! no blurries either with a default fsx.cfg

Out of curiosity, what are the shift-z and autogen trees fixes? Could you share your knowledge with us, please? :-)Gregor Gresiaczynski

Be interesting to hear how it continues to perform. I have found as I'm sure many have that FSX can send you out in relatively the same scenario and generate significantly different performance. One time up it's smooth as silk, the next a little less so, even though you're in the same or very similar situation. This makes it so difficult to assess cause and effect. Keep us posted and thanks!Noel
