Any way to compress game files on linux? I know that all games vary, content vary and so on, but is there any things i can look out for in like an average steam game which I can compress, and the game can still run fine, tools or programs or anything?
Often the oppositre is true, depending on case. Compressed files load faster, so if you have the cpu power to spare (which you usually have in games while loading) and loading speed is the bottle-neck then compression speeds things up, often considerably.
And even in the age of ssds processing data and moving it through ram is much faster than the disk, so even for writing some amount of transparent compression is possible without affecting speeds.
