mikee Posted May 25, 2019 Share Posted May 25, 2019 Hello guys , I am running Prepar3DV4.5 ( plus hotfix ) and everything was Smooth up to Now with no problems ! Today I tried to load a flight and choose a different Aircraft from my Selection favourite list ! It took approximately 2 min. for the aircraft to load !!! Then I tried to choose a different aircraft and still the same long loading time !! I then exit flight sim. and start it again , choosing a different flight with a different plane ! It took again 2 min. to load the aircraft ! Any Idea what is going on ? I never had such an issue before the hotfix or with any other versions of Prepar3d ! Any help will be much appreciated !!

Nick Cooper Posted May 25, 2019 Share Posted May 25, 2019 Hello, thanks for the question. Do you think it might be better asked at the P3D forum? Link to comment Share on other sites More sharing options...

Thanks Nick for your reply ! I just thought maybe someone from ORBX forums might encountered such or similar issue ! I will go ahead and post my question in their forums !

paj Posted May 26, 2019 Share Posted May 26, 2019 I've recently experienced very long load times to populate the aircraft list. The cause in my case was corrupted shader files. I fixed my problem by deleting: C: ► Users ► <Your username> ► AppData ► Local ► Lockheed Martin ► Prepar3D ► Shaders and the shaders were recompiled on the next run of P3D Link to comment Share on other sites More sharing options...

I followed your advice but unfortunately it did not fixed my problem , still long loading times ! Maybe it is the Combination of REX Environment Force and PTA that created the issue !

I have finally good news ! Today I Installed Couple of Sceneries and some Planes and when I tried to select a plane for my flight , everything worked perfect , In a matter of seconds my plane was selected ! I have No idea what caused the problem ! Thanks again for your help Mike Link to comment Share on other sites More sharing options...
paj Posted May 28, 2019 Share Posted May 28, 2019 I use REX EF too and it was during beta testing of a new build that my compiled shaders became corrupted which, in my case, caused the problems with the aircraft selection screen. Im glad your problem resolved itself. Link to comment Share on other sites More sharing options...

Thanks. sherm Link to comment Share on other sites More sharing options...
paj Posted May 28, 2019 Share Posted May 28, 2019 From my understanding of how shaders work, no. They get partially compiled at the end of the P3D launch sequence (just prior to the initial display of the Scenario screen) and fully compiled once a scenario finishes loading. But the compilation time is quick... usually a few seconds or less. Shaders are called on the Scenario screen, aircraft selection screen and whenever in flight. Whilst they affect rendering performance at these stages I don’t thInk they should affect loading times?? Loading times are instead proportional to the quantity of scenery and traffic bgl’s, texture files and simobject mdls. Link to comment Share on other sites More sharing options...
shermank Posted May 28, 2019 Share Posted May 28, 2019 Thanks paj, for that comprehensive explanation. Obviously we are dealing with a complex and layered software. Add to that the various scenery files we use, and the sorting out we expect of our computers. It is lot of zeros and ones we expect to be set in perfect order. maybe slow loading time is simply the cost of doing business for some of us. Comparing it to the preflight checks of a real pilot, from Cessna 152 to Dreamliner and military aircraft, it is like no time at all. sherm Link to comment Share on other sites More sharing options...
