About the screen resolution, well of course it just upscales the image from 720p to 1080p, but I thought it is clear enough that it doesn't make the game run native 1080p, like
said, 99% of the games natively are made for 720p. So editing the PARAM will just upscale
the picture. It is very easy to see that the 1080p screenshot that I postet is blurry compared to the native res. one.
