For my part I think that these problems are due to the fact that there is no official driver for the Silent Hunter 4 & 5 series the drivers stop at silent hunter 3 moreover we can see it at the end of the installation the hub which gives the info config is wrong all these problems are linked I am convinced of it the problems of shadows of light passing through ... clipping and I once again do it Ubisoft did not look into it .. and does not care I think
