Every time I start DR it reverts to resolution 1024 x 768 and Full Screen Off, although I set it to 1920 x 1080 and On. Other settings are saved however. I tried everything I can think of. Run the game as administrator, change the resolution and full screen in hardware config, save it and set to Read Only, but nothing helps. Every time it goes to 1024 x 768. I also updated to the latest drivers of my Geforce GTX 460. I have Windows 8.1 Pro btw. Does anyone have a solution ?
