Hi Christoph,

Happy new year for you too. Unfortunately we have some problems with the latest DRM patches. They modified a lot and some graphics cards don’t work anymore. During the holidays we tried to figure out where the problems are but without any success.

I will try to test your patches next week.

Cheers,
Christian
