P3Dv4.5 hotfix released

SOH-CM-2025
The P3Dv4.5 hotfix version 4.5.12.30293 has now been released. This is primarily intended to fix some performance issues some
people were having with the original 4.5 release version 4.5.11.29713. Release notes are here:

https://prepar3d.com/news/2019/05/115307/

Personally, I wasn't having any particular issues with the original 4.5. I don't know if the hotfix is severe enough to require new updates
from those developers who have already updated to the original 4.5, such as FSUIPC and Active Sky. I guess we'll have to wait on news,
but I might give it a go just to see. I guess I could always roll back to the original 4.5 client if required.

Thanks for the HU Rob.
I've installed the new client and on a very quick test have definitely gained some frames.

In my default flight which is in ORBX FTX EU England at Bembridge IOW in the FSX C172SP before the hotfix I was getting mid 30's now I'm hovering around 60 :)
Still need to do some testing in VR yet but it was flyable before as long as I didn't turn my head to fast, hopefully now it will be more comfortable.

I had already spent a far to much on a video card upgrade recently and was considering a CPU/mobo upgrade too but will probably be able to hold off on that now.
 
Well, I was not so lucky.

I installed the new Client, and P3D would not start. I then uninstalled the Content and Scenery, and reinstalled them. P3D still will not start. I ran the repair option of the P3D Setup. P3D will still not start.

I am so damn pissed. I have no idea what to do now. I do NOT want to totally uninstall/reinstall P3D, but it sure as hell is looking like that may have to be done. Damn it. :banghead: NC
 
v.4.5

Try uninstall 4.5 client , then install 4.4 client again , that with Windows add/ remove programs ~ and maybe remove last flight from P3d.cfg file ([FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif]SITUATION=C:\Users\your pc name \Documents\Prepar3D v4 Files\Previous Flight )[/FONT]

Ok, before I attempt that, I need to understand. I understand the first part about uninstalling 4.5 Client, then installing the 4.4 Client version, but you lost me on the rest of it. NC
 
Ok, I did the following. I deleted the Previous flight files. Then I uninstalled the latest Client, and reinstalled the previous Client. P3D starts now, but is the Hotfix installed now? NC
 
I made a balls up of the update and ended up doing a complete uninstall/reinstall. Grrrrr. My bad. Rushed into it without thinking deeper.

I was thinking I may also install P3Dv2.5 as a failsafe if my FSX should ever fail and there are issues in re-enabling the FSX licence. Can v2.5 and v4.5 of P3D live together on the same HD? Are there other issues within the AppData folder of Windows I need to be aware of? I am specifically thinking of the FSX Vs FSXSE and how you have to be specific in the order they can be installed in order to live together.

Hi , I found this in P3D Forum ,

https://prepar3d.com/forum/viewtopic.php?f=6322&t=132734 :)
 
Well my sim was running well with 4.5 so I figured I would install that version with the hotfix. Now my sim will not even start up wtf. :banghead:

Lou, same thing happened to me. Uninstall the latest client and install previous one. Worked for me. Hopefully will for you. N C
 
Went back to the original 4.5 client and she started up fine. Wonder what they did to increase frames with the hotfix because it doesn't like my machine. Maybe I'll see one more fix before it's all over with v4.

I dont know if it has anything to do with it but the only extra thing I did beside uninstalling the old client and installing the new one was to delete the content of the shaders folder.
Might be worth a try.

C:\Users\{your name}\AppData\Local\Lockheed Martin\Prepar3D v4\Shaders
 
Guys, from what I've seen in the other forums, if your sim does not start up anymore after installing the hotfix, it's most likely because of a module that needs to be updated.
Also, for performance reasons, don't forget to delete the shader cache before restarting the sim after hotfix installation.
 
Just an off topic question

If I go from 4.4 to 4.5 is that an update or full new installation

Thanks

Has anyone else noticed the change between 4.5 hotfix and 4.4 to the rendering methods of PBR materials on aircraft? It's very noticeable. Makes me think the hotfix was more scenery based rather than simobject based.

Eg same settings on stock as a rock P3d ( I have to ) what was dark is now washed out. Same video card drivers.

Install method was complete uninstall and clean of all p3d v4.4, restart computer , complete install of latest 4.5 all content/client. I know it's overkill but my computer is also a test computer and must remain stock as LM intended.
