After resetting it works again. But if I mess too much with settings it will stop working again. The fact is the process of messing with settings breaks it. If I find working settings and start messing too much in the settings but still end up with the same settings it worked a minute ago it will refuse to work and break. Not even changing video mode back to default (software) will help. The only help then is to reset everything entirely. The settings are way too complicated and scattered everywhere and changing some settings changes other settings and you have to go back to change them again (sometimes it works, sometimes not) and also sometimes changing something makes new options open up (sometimes not) and sometimes video mode goes back to software after I just set it to hardware high resolution. Some settings are not saved (FPS limit is never saved; it is always unchecked when I open app; I have to always check it; why?). It should be more clear. It is not clear at all. Sometimes the button to open options/settings while in game stops working.
Can you recommend some settings for best video image quality and highest resolution possible?
