Sea of Solitude - Settings?

How to change more specific graphics settings, than just resolution and V-Sync (such as shadows or view distance)? The game tries to overheat my GPU (4GB), if I run it as is (max resolution and everything enabled), and I would like to avoid it.

I've already decreased the resolution to 1280x720 and disabled V-Sync and AA, what else can I do?

Edit. I've completed the game, but it still would be good to be able to change the settings.
