I think the problem was with texture. As the file was big it took much time to load and had high disk uses. As they change format files become smaller.
They create that trailer with bannerlord assets with their own software called machinema. It's for all users who want to create cinematic from game assets like tree, character model, castle etc.
BL has the worst lighting in modern games. If it can be improved with ray tracing then it's not bad.
They create a nvd_test branch on steamdb few days ago. Maybe they were creating and testing that demo video.
It's beta version so it can have bugs. That's why there's stable version. Fixing bugs could take time. I don't know why you're so upset. It's only 2 days beta is live.
Why would they release a hot fix if they are going to push 1.4.2 to main branch?
Time to upgrade my one handed park ? For empress Rhagaea.
Yesterday they added 2 internal test. The patch may come in Thursday.
You people are going to be so disappointed when the patch will release. Even one dev said 1.4.3 will be same scale as prior patches. The size increase maybe because of code refactoring.
