Hi,

 

Looks like Pete Dowson found a way to trap and prevent P3D from crashing from the dreaded g3d.dll error. The fix is in his latest offering of FSUIPC (ver. 4.827) and is available for download at his website. Seems its the same fix that was required for FSX.

Grateful for Pete for putting this into FSUIPC for Prepar3D despite his initial reluctance. I share his sentiments though. I wish this was addressed at the core of the sim and there wasn't a need to depend on a workaround to stop a sim that is actively in development from crashing. I'd understand if this was a new error but G3D crashes have been around in FSX forever and just carried right over into this one.

That's great news. I repeated some of my flights in FTX PNW Seattle area where I usually experienced CTDs after 5 min or so. After I had installed the new FSUIPC I was able to fly 2 hours in Seattle area (high settings, fps 15-25). Even with heavy clouds and dusty weather settings (4096 REX textures) the sim kept stable.

 

I would say the problem is fixed.

Hey Mike, I have been away from the FS side for quite a while, how do you know it is a g3d.dll error? Does it come up when it crashes as so? Last night I got an "Prepar3d.exe has stopped working error," but it didn't explicitly say that it was a g3d error.

If you check event viewer you can check the crash reason.

That is what I figured... I will have to check next time. Thanks Paul.

If you have any parking without a path link to aprons runways etc the scenery will crash by g3d.dll. Try to inspect your scenery .
