Are there any major changes between versions?
I get very confused about file sizes, that's why I'm asking xd
PD: very good game, I love it <3
Thank you, glad you like the game.
Currently, there are only minor differences between them; the newest version has more progress than the rest. DX11 has more content, but the shaders and details are much less appealing, as it's a fallback option for lower-end systems(And I forgot to adjust the compression ratio to best, so it's 150MB larger).
I'm not an expert on file compression. But Zip appears to take up more space than Rar.
