so you have to wait for unpacking the game (takes for me 5 hours) and after that the game is compiling the shaders (takes between 20 and 40 minutes)
Nope. The PC is good so far.
Core i7 9700K
Samsung 970 PRO Plus 1 TB NVMe M.2.
Refund the game at Steam and buy it again at Epic. No problems there. Downloaded after 20 Minutes and all done in round about 5 Minutes
