I’ve checked your world @nefandi and it looks all small and decent in size. Your worlds @jdforever seem to be ok, apart from
wildmount which is really large (it was 125MB, see World Size Check - Docs - The Forge for help)
That being said, I don’t know if there’s some issue in Germany right now, but we’ve had a few reports within the past couple of weeks of games being slow to load, but which we can’t reproduce on our side. We even tested games of users live at the same time as them, the same game would load within 5 seconds for me (and I’m in Canada, connecting to the server in Amsterdam) while it took multiple minutes for the users (who is in Europe).
The only conclusion we could come to was that it was likely an issue with the ISP. We even confirmed that with a user who said they had no problems when connecting via mobile hotspot, but would be slow to load using their home internet, and another one who connected via a VPN and said it fixed the problems.
Our general advice is to check the world size, try to launch in safe mode (i.e disable all modules), make sure you have hardware acceleration enabled, and that your actual GPU (rather than “SwiftShader” or your CPU’s integrated GPU) is listed in “Unmasked Rendered” on https://webglreport.com
If none of that helps, then it’s likely an issue from the server, though we haven’t had any slow downs on the European servers, only reports that seem to point to the user’s ISP (or more likely a larger internet routing issue).
I would recommend you try our demo server (https://demo.forge-vtt.com) and if it loads without issues, you might want to switch your region to North America for now, then try again in a week or so, and see if whatever network issue your ISP had has fixed itself.
I hope that helps
