I get these pixelated edges:

UPDATE: This problem is solved by changing Voxel-Based Global Illumination.
Here is my configuration (optimized for GTX970):
e_svoTI_ResScaleBase=0 (should always be 0)
e_svoTI_LowSpecMode=3 (default for is 6 for low, 1 is very high=less pixelation but slower)*
e_svoTI_ConeMaxLength=16 (default is 8, higher is faster and lighter)
e_svoTI_DiffuseConeWidth=32 (default is 24, higher is faster and darker)
*I use LowSpecMode=3 because i can get 58-60fps in Rattay with it but LowSpecMode=2 would reduce pixelation to almost nothing but then i only get around 40-44fps.
