I have the same quality renders than you have in your previous post with Apollyon, and they were like this before, I see no difference (also I got the free version from GoFile that is in the OP of this thread, no idea from what version it was leaked).
From what I read renders are 720p what is considered low compared with most games that have 1024p or higher resolution renders so you will notice many imperfections due to the low resolution. Fortunately I play this game mostly for the story than the high graphic quality hehehe.
But in the animations you see difference right away, they are at least 1024p if not higher, you won't notice so much grain in them, even the color tone change. Your post have screenshot of renders/still images of Apollyon gallery entry Being Human and
PaxHadrian17 post have screenshot of animations that have higher quality than the still images (Gallery entry: Apollyon: Thanks). Both are the same quality I have in my version hehe.
