[SE] [S] Snow appears pixelated under lighting

brubruQC1998​  Honestly, I don't see the issue, even downloading the images and staring at them on a high-resolution screen.  I do see the slightly jagged edges of the circles of light, but that's always going to be a problem to some extent when working with square pixels.  The only thing I notice in the first image though is the bricks under the lighting.

Anyway, I'd still like to see a dxdiag.  I'd also like to know whether it helps to disable post processing, which is a check box with the other graphics options.
