OK …have done two test flights now.
Is much better on the ground now…but when it comes to flying…so wheels leaving the runway…the stuttars start again and last till i landed again.
I think I have done now everything what i can do.
So I need to wait to fix this issue by MS with another Win11 24h2 update.
Or reinstall to Win10 or Win11 23h2 again…or just buy a new PC that follows the requirements for Win11. Guess i need a new one nevertheless when it comes to MSFS2024.
I thank you all for your affords as Im not willing to test anything further…and hope you wont face these problems.
