182 Memory leak P3D V5 HF1

Post by Kaselite2 »

Hello,

I posted this research over at P3D: https://www.prepar3d.com/forum/viewtopi ... 22#p220622

I thought the simulator was leaking but it turned out to be windshield.dll. (version installed is: 20.5.10)

Please note that this is a fresh install (incl. P3D V5 HF1) from the V5 installer with the additional update using the checker in the installer. (i also ran the checker manually to make sure there was not another one).

I have renamed the DLL and all the memory leads are gone (cockpit is a little windy now... just kidding).

I found the issue through this post: viewtopic.php?f=94&t=70594&p=536781&hil ... ry#p536781

Hello Kaselite2,

It sounds like you're using multiple monitors. Do these make use of multiple undocked windows, or is it one, full screen window stretched across multiple monitors?

Thanks,

i have two GPUs with 2 monitors in each GPU. I'm using view groups across three of them and a Realsim gear on the fourth. The memory leak occurs even when im using just 1 monitor i.e. no view groups. I tested that too.

Thanks for the info.

Just to clarify, when using just one monitor, does the memory leak occur only when just a single P3D display window is in use? i.e. when there are no secondary, undocked windows running?

Hello, i applied the recent update but then i renamed the DLL again. Flew without a windshield for a while. Yesterday i has a little time so i reinstated it again did a few test of short flights and it was ok. Today, at 28 mins into the flight it happened again. It's still happening with multiple monitors but its happening with in my case 5 monitors. My config is:

GPU0 (2080Ti) - three monitors (Foreward, left/right windshield)
GPU1 (2080Ti) - three monitors (left/right window and 1x gearsimgear gns530)

If you want any addtional info... let me know.
