Momentary lapse of reason

Recommended Posts

In the moment of my weakness i jumped to P3D 3.1

 

But from the beginning.

I set brand new Win7/64 installation first.

I installed P3D 3.1.2.15831 and then ORBX Global / Vector / REX Texture / ASN / REX Soft Clouds / FlyTampa Vienna and the rest of those.

My GTX760 is supported by latest NVIDIA driver 361.75 WHQL.

Apart of PFPX, Adobe and Auslogic Defrag my Win7 is free from other software.

 

I start up P3D on default airport with default Mooney.

During first circles around airport i already have noticed stutters.

Initially i was thinking that my settings were too high.

I started to change graphic settings, from very low to very high.

Regardless of settings stutters are present.

I have tried to : 

 

- change screen refresh rate 60 to 30 Hz

- set VSync in game in in NVI, no VSync

- tesselation on/off, and different tesselation factor

- different shadows, no shadows 

- water settings from low to ultra

- scenery objects density

- HDR on/off

- limited/unlimited fps

- limiting fps inside P3D or NVI

- for sure some more but do not remember now...

 

Apart of adding 'affinity mask=14' ( i7 without HT ) i did not change anything in P3D.cfg

 

Whatever i set stutters are present on default airport with default plane !

 

Will spend coming weekend reading and testing, but i am afraid that after weekend i will apologize my FSX ....

Artur,

Based on some other threads, check the "Dynamic Reflections" setting.  If this is set at the high end, move ot down and see if that helps.

Just a guess...

Good luck.

When I install a new sim, I just install the default sim and run it without any add ons to see what happens. Then  I add one  thing at a time, and check the result. Makes it very easy to find something that is causing a problem.

Have to agree with Bobsk8, I don't understand trying new program and dumping every add-on you have in it before finding what you have with the base program.

 

It totally bypasses the 'learning-what-you-have" before loading up additional burdens.

 

Having said that, I still believe you can run P3D 3.1 just fine. Others are. 

Might also help if we knew comp. specs other than 760 nividia card

Jimcarrel - if i have to skip any of mentioned addons, then better i skip whole sim and get back to FSX ...

As i said, i was testing sim on default airport with default plane, without ASN.

I have no FPS issue, so far it looks like this sim is stuttering by it's nature.

 

Neucoas - i unchecked most of Vector options, beaches and few other left on.

 

Alderon57 - Dynamic reflections are compulsory unchecked ( this option is not for my computer )

All of the OP before mentioned addons and many more work flawlessly on my sytem (win 10, P3Dv3.1, i7 3820@ 4800, HT on, AM=85, GTX 780, 1920x1080). So it seems to be not a P3Dv3 problem but rather a  hardware / settings problem.

I found that a proper affinity mask, limited frame rate, and an overclock reduced my stutters in relatively cloud free conditions. You can see my journey from nauseating stutters to smooth flight here.

However, in cloudy conditions with AA, apparently I need a GTX 970 or better to render clouds at a good frame rate (a little ridiculous if you ask me).

You are not following my logic apparently. Install P3D, and nothing else at first. See what FPS you get and how it runs. If it runs good, then something else you installed screwed it up. One at a time, add all your add ons until you find out  the culprit. Stating that  you have P3D and half a dozen add ons and it doesn't work, so what's wrong, would be impossible for anyone to figure out on your system. It's called troubleshooting.

ailchim - that was good, LOL :LMAO: 

 

So far i test my stutters taxing or being precise, making slow circles.

I do not fly, no ASN so clouds cannot be the issue, not yet ...

Have you tried taxying in slow circles at a default P3D airport? Are there still stutters? What about in flight? What is performance like away from the airport?

Traffic Pilot - i'm doing my testing only at default airports with default Mooney.

 

Daniel Moser - very interesting study. So far after few hours of checking and testing i found out that internal limiter is better solution than NVI ( contrary to FSX ). Also i see that limiting fps at 40 is best so far. Anything below 30 is not smooth. Vsync is not changing much. Frankly, also Affinity Mask seems to have minor if any influence.

Beardyman - if you want to save some time and aggravation

 

1) uninstall everything

2) Install p3d 3.1

3) MAKE NO TWEAKS AT ALL

4) ADD NOTHING AT ALL

5) Fly - set the sim to get the best visuals and performance WITH NO TWEAKING

6) when happy - add your addons ONE AT A TIME and retest\

 

 

also what cpu are you using?

good call: HT on, AM=85

 

also keep addons off of core zero (LPs 0 and 1) with a .bat or proc lasso or similar if possible

Also, I found that Tesselation at highest settings, coupled with fps set to 27 in P3D, with vsync off,

got rid of the stuttery scenery for me.

Never really had a blurries problem.. just slightly stuttery scenery

On my system things are getting better when FPS limit is going higher.

27 fps - things are not so smooth, 30 is better, so far 40 is best.

Other graphic settings seems to have no influence really.

Tesselation - i do not see any difference if this is set to low or ultra ( graphically also cannot figure out any difference )

So Artur,

 

It's common to find that the FPS is maintained at a lower rate than the prescribed limit, and that raising the limit can get you closer to the rate at which you originally wanted.

 

For instance: A limit of 30 FPS may actually only get you a 27 FPS on average. Raising the limit to 33 FPS then may yield an average of 30 FPS, and then so on.

 

This may be special to only system, but lowering the FFTF slightly brought the average frame rate closer to my prescribed limit and made things smoother. You can experiment with that as well.

Hello Daniel - now i turned on HT and checking if this will give any improvement.

FFTF=0.1 seems to have no influence for me.
