warn+all log

The complete in-game message is: "Unable to create render target texture
width=2048 height=2048. Shadowmap quality will be reduced next time you start
the game."

Obviously reducing the shadowmap quality did not help.

The error happens either when trying to run tutorial #4 or start a new game.
Tutorials #1-#3 work fine.
