From day one after the upgrade its like that for me....even after clean reinstall of game its the same...impossible to use DX10/11/12 (V1)
On DX10/11/12 (V2) the error dissapeared before few days but planets stay stretched vertically...
In Vanilla always bad ping and heavy stuttering
The only one with no issues for me is OpenGL....but push my fans spinning all the time /not at max ofc/....and the other one is with the stretched palnets DX10/11/12 (V2)
