Unusual problem and its solution: MSFS got stuck every time at 80% loading screen despite empty Community folder

Never seen that before: MSFS suddenly always got stuck during initial blue progress bar loading up to ca. 90% without having changed anything in MSFS whatsoever. The only thing I had changed was my GPU: I had returned my previous RTX 4090 and re-installed my previous RTX 3090 for 2 days until my new RTX 4090 arrived today. When I was finally finished installing the new RTX 4090 this problem occurred for the very first time, even with an empty Community folder, something I have never ever experienced before. After a short moment of despair I decided to delete the Nvidia cache directory, reboooted e voila: ca plan pour moi!  who would have thought. hope this might help users in similar situations.

how to delete the Nvidia cache.

Yes I tried this yesterday. 

I am not able to delete all files. 

Some are in use by explorer.

those don't matter. they are not relevant for MSFS.

I have seen this video, very interesting and I tried it a little while back. How often should you do this, every flight?

as often as you like 😀 but necessary only if you encounter any problems such like the one I ran into.

Strange problem....  😉

Not sure about his explanation of the issue, tbh, so I must be misunderstanding his problem because...don't we ALL get stuck for 3-4 minutes waiting for the sim to load before we get into the main menu? Or is he saying that he is actually getting stuck after he clicks the "FLY" button?

1) yes

2) no, because

a) despite an empty Community folder, so nothing that could cause incompatibilities there

b) not stuck for 3-4 minutes, but eternal.

otherwise there would have been no need for this, his, my post. 😀

Yes we all get stuck for a few minutes at loading, regardless of an empty community folder (it is not an addon issue).

You are correct, "stuck for a few minutes" is not the same as "stuck eternally" 🙂

I did not understand that you were stuck eternally... I assumed that perhaps you just ran out of patience waiting for that 4 minutes to pass, and perhaps you only THOUGHT you were going to be stuck forever.

Glad it worked for you though. I tried that fix weeks ago but still have a solid 4 minute wait at the load screen every time I boot up Msfs, even with zero addons in the Community folder.

indeed, that's why I described it here. I had absolutely no idea but since exchanging the GPU for 3 different models from 3 different manufacturers ( PNY RTX 4090, EVGA RTX 3090, Gigabyte RTX 4090) was the only change in my system within the last 2 days I thought this could have been the only cause of the problem. leftovers from a previous shader cache that might have the potential to confuse MSFS. After I deleted it all was running smooth again. but now that you mention it, perhaps the new nervously blinking RGB lighting scheme on the Gigabyte 4090 confused MSFS 😀. anyway, I'll always take a new RTX 4090 at $ 200 less than the previous one. let's see what the future brings for RTX 4090 prices, I have 30 days left before grace/return period runs out.

perhaps this got also "stuck" or lost in translation 😀. I thought "got stuck" in english always implies "forever", but obviously not. I should have been more precise.✔️

Yea, hehe...it's sometimes described as a "crash" when you get stuck forever, I suppose 🙂

 

I simply started this thread because I thought it was so unusual and I saw absolutely no other reason for a vanilla MSFS with no addons in Community to "crash" and no other modifications except for changing 3 GPU's within 2 days.

Yep, seems this might be a good idea to sticky this.

IMO, a game should probably be re-caching any necessary files itself, if a hardware change has been recognized and requires it. At least, that's what I've seen some other games do, when it comes to graphic card and driver changes. Dunno why MSFS isn't doing this.

So I just registered just to say Thank You to the author of this thread. I've spent the day trying everything but nothing worked except what's described in this thread. I'd like to add this other video that also helped, as the NV_Cache folder seems to be gone and there's another process to delete the shader's cache. Also it shows you how to increase the shader cache size: 

Again, thank you!
