You're not alone! Same problem, same sadness... and I totally agree with Dragon Brother. I play on a 50" screen, 1848 x 1026, so trust me too marcuswob, there a big texture difference with config like this.
May someone has already try, but, why don't send a mail or call kochmedia? There not great for help, but helpful anyway. When Sacred 2 was out, I've buy it the fist day and it was impossible at this time to config key, just have to wait a patch, but I've call them and send me the way to config them on the default game config.
So, may a new patch is building to fix this bug, but there is an other solution to wait it?
Gonna try and will give news.
