FS2024 (1.7.27.0)  was running perfectly in the latest Beta.  Flow Pro was working as expected.  I decided I would reinstall ChasePlane (experimental).  Chase Plane had been working well several months ago but I uninstalled it so I could work on native controller profiles.

Before I installed Chase Plane I used the MFS Cleaner Fixer app to clear all the shader caches and my rolling cache.

I then installed Chase Plane and started FS2024.  Loaded at normal speed to 87% (about 90 seconds) and then stalled.  During the next five-minutes loading got to 96% but never progressed from there.

I verified there was no rolling cache, I deleted all the steamed packages, installed the latest nVidia driver, rebooted the system.'

Started FS2024 (1.7.27.0) and it stalled at 89% and then never got past 97%.

Same result with FS2020 (1.39.12.0) 

The programs seem to be stuck trying to find Default_Global_XEN_Supperresolution and Default_Global_XEN_TrueHDR in the registry.  They just keeping trying to read the key and not finding it.  

Apparently I deleted something somewhere but have no idea how to fix it.  

Supperresolution seems to be an AMD thing.  I have an AMD 9800X3D but neither monitor is connected to it.

TrueHDR seems to be a downloaded thing to give more control of the HDR process.  I turned all HDR references off but the sims still try to load it.

What to do?

 

I helped someone else with this behaviour a good while ago and in his case the cause of the issue was a corrupt hosts file due to using the Map Enhancement program which edits that file on each launch and reverts the changes upon closing it down, but sometimes that process doesnt do it and the hosts file goes into almost a loop where it just edits the file, but does not revert the changes and the file gets filled up and if those entries are still there during startup without using the Map Enhancement, the sim does not have access to the servers needed for loading in scenery. The hosts file is located here "C:\Windows\System32\drivers\etc\hosts" and here is a guide for resetting the file to default state. I would give that a go if you see that the file has been edited recently or has different dates than the other files in the same location.

That sounds like a server issue.

Maybe load with an empty community folder?

I flew with ChasePlane (Latest Version) today and the sim loaded quickly without any issues.

Last resort is a full clean install. I had to do it after SU5 and It took about 30 minutes for me to be flying again.

Benjamin - thanks for reminding me.  You were correct.  I used to have a little batch file with a desktop icon for resetting the host file.  I'll have to find it and put it back on the desktop.
