@Naroxas44, i ran DxDiag again and it shows me "Feature Levels: 12_1,12_0,11_1,11_0,10_1,10_0,9_3,9_2,9_1".
My system has no integrated graphics (neither on mainboard, nor in CPU). That is the only videocard in my system.
On launcher log file, i found this:
Found D3D adapter 0: NVIDIA GeForce GTX 1080 Ti (D3D_FEATURE_LEVEL_12_0)
Ignoring software D3D adapter 1: Microsoft Basic Render Driver (D3D_FEATURE_LEVEL_12_0)
