Not sure if this helps but check your sound settings and change them to something other than "default device settings" like I did and see if you experience changes in your FPS when switching views.





Let me know if your FPS changes.

All of my issues appeared to be caused by by recent Windows Updates changing my default sound settings.

Monitor with speakers using HDMI connected to my 1080ti which had previously been disabled was re-enabled after the updates. This monitor then became my default sound device instead of my headset.

Hard to believe because the settings were changed that it would drop my FPS below 5.

Once the sound issues were corrected, my FPS was back up btwn 20 - 80.

I just have to remember to check these settings each time after an update and before I use P3D.

Did you have the OP's posted problem of FPS drop when switching views?

Hi,
I tried to using p3d with a couple of my headset but nothing happen, I'm considering the idea that maybe the problem is my logitech Z623 audio system, beacuse if i deselect audio by pressing Q or set primary playbck and voice playback to Realtek digital output or C24FG70 NVIDIA high definiton audio as you can see in the screenshot,in short, anything, excluding audio speakers, p3d works perfect with 100 fps but of course with no sound, i have another logitech speaker+ subwoofer which i'm using with my PS4 in my room, i let you know if it will work.

I've tried to run p3d with an another logitech speakers+subwoofer as i mentioned before, but the issue persist unfortunately, i don't think is my sound card, beacuse it's new and my PC is not even a year old.
I don't know ):

Hi,
Today i've ried another couple of speakers of my friend but issue persist, is more than 2 month that i have this issue, i'm really frustrated, if anybody has my same issue, i would really appreciate some suggestions.
Regards

Was a Windows Update the only thing that changed on your system since your last good flight?

Which aircraft are you testing?

Which version of P3D?

Yes Windows Ubdate was the last thing i did and Nvidia Driver 416.16 whql(But i also try the older ones without any effekt) ... and i try normal F22 Aircraft or the Smaler Turboporbs ! I Use P3D 4.3 ! I Think Windows 10 v1809 kill P3D

Hi, now have a same problems. Update last version of win10 and have this issue with p3d. Very very bad :(

...in my case try to test a different drivers nvidia, but don't resolve. Now at moment investigate on audio parts.

and...if press Q (during fps drops), no problems, fps go to high value...when reactivate audio...fps down to 3/4fps :(

Windows 1809 killes our Sounddriver in P3D V4.3 and set it too default !
Now i deinstall all my Sounddrivers and Install the Sounddriver from Motherboardsite again ! AND...
IT WORKS NOW ! No more FPS dops right know !! Now it runs for me

Reinstall realtek drivers...and at moment no problems!
