Stuttering is confirmed for 2.4 too.

 

It is not only a micro-stutter - the whole simulator is stopped completely for split second, skipping input. The more higher settings you have, the more pronounced problem is, but even at almost blank world this stutter can be felt, for less periods of time and with less skipped input, though. For the biggest pauses, spikes on CPU graph could be clearly seen, where main processing thread core usage drops by ~10 percents down for no reason. Affinity mask setting makes no difference, whether it is absent or set to 14 (for my 4 core cpu).

 

My configuration is Core  i7 860 at 3.7 GHz, GTX 480 x 2, BenqXL2411T in 120Hz lightboost mode. I tried both single card and SLI - but stuttering stays the same regardless of SLI settings.

 

I'm a long time quake player, so I know what is a smooth game and what is not (as well as fully aware about related placebo effects) - and Prepar3d, right now, is a bit jerky. However, I'm agree that it can be my configuration which acts funny exclusively in Prepar3d - but please note that other games I play (QuakeLive, BF4, War Thunder, World of Tanks, DCS World, Arma 3, DayZ and lots of single player titles) are running smoothly or very close to it.

 

P.S. I did my testing on clean Prepar3d 2.4 install, with no other add-ons installed, default flight from LM.

 

P.P.S. I think I am up to something - after unchecking Hardware Tesselation option in settings, I don't have now any serious stutter with input skipping. Will do later more experiments with and without it checked, but now it seems that reason for stutters is somewhere in tesselation related code.

Ever thought about the idea that your system is not powerful enough to run Prepar3d v2? Seems quite ancient to be honest...

Not the best hardware for P3D v2.4. With this rig you're at the bottom line what can run P3D v2.4

The problem I am experiencing (periodical complete freezes of the simulation) has nothing to do with overall system performance (i.e. number of frames per second my system can achieve). This is two different beasts. And BTW the FPS which I can achieve on my system is totally suits me (18 FPS in CS777, other crafts have 25-40+ FPS with all sliders to the right). Also, if you would read my post, you would notice that it seems that disabling Hardware Tesselation removes stutters altogether.

 

But I can assume that you are partially right - starting from some time Prepar3d may not be tested well enough for older configurations, like mine, and hence, some bugs were introduced in the later builds. Need more testing though in order to either confirm or deny it.

 

Soon I will upgrade to GTX 980 - but I'm sure that stutter and microstutter problems will not go away with this upgrade. According to my gaming and 10+ years programming experience, if program is poorly coded, then it will behave poorly on any hardware, no matter how powerful it is.

 

Anyway, later this week I will do more profound testing. Right now I have not too much info to base any conclusions on.

This GPU with your existing CPU?

I really don't understand what you are talking about. My system fully conforms to recommended requirements, specified here: http://www.prepar3d.com/product-overview/ And apart from this stutter problem caused, probably, by bugs in tesselation code, everything else works without a hitch.

As if it could bottleneck my current CPU. But if it will do it (I really, really doubt about it) - then I will promptly upgrade to latest Core i7, they are selling for two weeks in Ukraine now.

wrong post

More than once when using the "clean install" I've seen stutter issues appear after a roll back.  The only method which has worked 100% of the time for me is to uninstall via the windows control panel.  But enough of this sidebar....back to flying...(or complaining about stutters).

 

As per nvidias instuctions and communicated via NickN at simforums, the only way to install a new geforce driver 'clean' is to remove using the control panel first, reboot and then do a 'clean' install option from the new driver.

 

Just selecting clean install without removing the old driver is not the correct way.

 

FYI,

 

After many fights with my notebook I found what was the cause for my periodic stutterfest problem. My Cpu was having overheating when the temperature reach 96 C the system reduce the frequency for half causing stutter.

 

I changed my power settings for reduce 12% of my frequency cpu and now i have maximum 76 C and no more  periodic stutters.

 

ok! My problem was solve. 

 

Please folks check CPU temps when you are using p3d.

 

 

I dont think many will be running P3D on a notebook.

 

This program chews up and spits out CPU's and GPU's for fun on even the most powerful desktop.

 

 

disabling Hardware Tesselation removes stutters altogether.

 

 

+1 but then P3D will crash with an R6025 error . Which P3D say they cannot replicate despite lots of people suffering with the same issue.

 

Let us know if your V2.4 version continues to work fine with tessellation ticked OFF. I haven't tried it ticked off yet but am fully expecting another CTD.

Have no fear...where I had 'some' micro-stutter and screen update, (and my system is very powerful...) in v2.3, the first thing I noticed was that now, I had  (in v2.4) very serious stutter..and as you had seen...almost a pausing of animation. It is not your system...it is the coding in v2.4.   I went back to a full install of v2.3, and all such micro pauses and other stutter artifacts...went away. Man..it is what they did to the coding to 'fix things'....

i5-3570k 4.2 Ghz, GTX670, just purchased P3D V2.4 yesterday, installed FTX Global, Aerosoft A319, ASN, FSDT, Flytampa Montreal, and ported 2 sceneries with EMT, setting up this tweak : http://forum.avsim.net/topic/444793-one-tweak-to-rule-them-all-how-to-set-affinity-mask-correctly/?p=3013604

 

No stutters loading up the F35, but i'm currently having MAJOR stutters (at least 4 seconds freeze) with the A319, CPU reaching 100% prior the freezes. Still looking for solutions. (Current AM = 14 )

Excellent guide but I think you do not need AM with 2.4 - correct me if I am wrong

Indeed I think the AM = 14 is redundant so I removed it. Trying to reduce my cloud settings to 1024 see how things will go. Very little to 0 stutter on my Majestic Q400 so far. A319 Aerosoft is still a major pain in the (@#^$!

You running unlimited frames with 319 - thats what I do have no problems - I am using 512 res clouds also

Im using these now: http://www.robainscough.com/P3D_V2.php

 

Where do you change the 512 res clouds? on REX4 settings? or via P3D.cfg?
