First Start takes forever

Hi,

For a few days (since returning to POE1), the first start of the game after booting up my PC takes forever.
For a long time the POE Game Tab shows "not responding" and takes like 3 minutes to load overall.

I tried already some Stuff.

1. As I'm launching via Steam, I checked Game Files, and he found 480 files to be downloaded again, but no change.
2. Tried the boot parameter --nopreload
3. cleaned Chache
4. Ran SSD Check

I did not yet completely reinstall POE, as I'm always afraid of this step :-) .

When closing the Game and starting it again without any Reboot of my PC the second boot is very fast (like 5 seconds) ... like it used to be always.
So probably something related to RAM ?!

Is this any known Problem ?
Any tips on what else I can try?

Cheers
Daniel

P.S: I don't think I have any hardware faults here, as every other game is fine. I have a good PC, and I can tell you it has never been this slow.

Seems like updating nvidia Driver to Version 581.57 solved the Problem

(the "old" Driver wasnt really old...last updated in September)
