I have posted at Steam/JNPG forum that my green grids render super fast now, and since yesterday I have noticed another plus with this version. 1.4.1.3
The game now renders faster in general. Nothing has changed in my Box, it's all the same. Still using nVidia Driver 372.70 too. I know there is a new one (372.90) but I'm not ready to experiment with it.
So whatever bugs and fixes were corrected something is making the game render (for me) better than it ever has.
Here are my graphics settings. The only reason shadows are on the low side is because long shadows during game play mess with my eyes.
Kudos Devs!
