I've just installed Seasons after reinstalling everything else and all my graphics are on the highest settings; 1280x1024 resolution smoothed edges, reflections etc and the game runs very smoothly. However...THIS is what light snow looks like:

The further i zoom in the more pronounced it gets because it only occurs around the edges of the screen and within the boundaries of the lot and only where light snow has fallen. I tried putting on square pixels because i read thats what to do when the screen appears stretched but it had no effect. Is anyone else experiencing this and does anyone know how to fix it? I'm attempting to update my drivers now to see if that fixes it. I'll get back to you on that.
