I just took off at 11S in Orbx's PNW...with ASN giving a very heavy cloud base and overcast.  The sim today at this moment in time is giving me 18-22 FPS.

 

What is totally weird, is that under normal circumstances, whereby the sim is giving up only about 18 or so FPS...I'd get very little, but STILL THERE, micro stutter.

 

Today though...it is as smooth as glass, as I took off out of 11S and did a hard bank (in the Raptor) towards the coast..and then did a fly over of Seiku harbor.  I then flew inland at about 500 feet over the mountain tops (I'm in pause right now to post) and with all this heavy cloud (ASN), still have smooth as glass advancing animation. So...I don't know what gives...does P3D v2.2 have good and bad days?!!?  LOLOLOL!

 

Just thought to post this....so weird. So weird.

 

Tomorrow, I'll have a situation that only renders 18-22 FPS, and the micro-stutters might show themselves again.  

 

Oh well...I'll take what I get....and will at lest enjoy the smooth animation of this particular flight.....

Sounds like you may have some background service or program kicking in. Maybe AV, Windows, Acronis or some other program updating...

Most likely cause is Time of Day ... and if you have Cloud Shadows enabled.

 

I demonstrated the issue to LM and sent them the saved flight and weather so it would be easy to duplicate ... Sunsets or Dawn if you have a cloud in the distances that passes your view (between you and Sun) and you have cloud shadows enabled you can see a 50% fps drop as the long distance shadow calculation stress out the GPU while the cloud pass by the sun.  When I fly Sunset/Dawn, I turn off cloud shadows (they don't really add much visually at that time of day).

 

Cheers, Rob.

Hi Rob, yes..I have the entire Shadow Mask enabled.  It is about 1:40 PM that I am flying....and so very smooth...this is nuts!

 

 

Shadow Mask enabled.

 

I think you mean Cloud Shadows?

That could be, but to be fair...I always turn everything off...so this is the same working environment, that might tomorrow...or any other flight for that matter, I guess...give way to micro-stutter.  Boy..if I could only also 'dial this in'......!!!!

I think you mean Cloud Shadows?

Yes...all forms of Shadows, I have enabled.  Yes...anything that has to do with a form of shadow..is enabled in my flights.

That's it. It's over. Mitch is going back to (INSERT SIM HERE).

I second that: this is exactly my experience. Hopefully, they will change something in the cloud shadow logic to take into account the light incidence angle and minimize this weird effect.

You are kidding...RIGHT?!?

 

Just call me the P3D 'hook in the mouth guy'.   :lol:   I'm having WAY too much fun...so I expect some sort of federal tax to soon be enacted.  The P3D 'way-too-much-fun' Tax enacted by Congress at 7 %  :ph34r:

Wow, that's really interesting what Rob said. Being a P3D virgin I hadn't even thought of that. Nice to learn something new :smile:

The micro stutter issues go way back. Word Not Allowed's talked about, I talked about it, many had it, and with 2.2 it's still here. I don't have them anymore in FSX though.

One thing that was discovered  was it did not matter for the most part what your hardware situation was, nor the internal graphics settings. Even turning everything down, the stutters were still there.

It is a mystery.

Have you tried the Adaptive-Sync-Setting in the NVidia manager?

 

It works very well for me. P3D now is very (not totally though) smooth until I drop significantly below 20 fps. So with reasonable settings (oh how would I love to have dynamic settings in P3D) the experience is very good for me now. I will install the EVGA Precision-tool tonight and see if that improves things further.

This is what is killing it for me. I ain't gonna to move across to P3D and leave my lovely smooth FSX behind. OK, I know there are many benefits of P3D over FSX, but something as intrinsically engrained in every flight, such as smoothness, is a big deal for me. I wonder how many other guys share similar concerns and whether or not these concerns will be addressed by LM...

Well LM already got my money because I was convinced 2.2 would be the big breakthrough. I too have silky smooth with FSX, even around KSEA-ORBX and almost everything maxed and DX10. 

 

I'm good.

I was flying in the PFJ and forgot to check the Precision X when i had some minor stutter. They do vanish when enabled the limiter in Precision X. Down to 20 and its fine here. Autogen can stress the system though.

 

Why do Precision X sometimes disable the limiter by itself? Maybe after a system restart?
