If you really cannot live with a 500gb HDD for $30 you can a 500gb SSD for $60 which is still cheap. 2nd hand they’re practically free.

Also its not just league of legends, it also plays Rainbow six siege its really not as bad as you are making it out to be.

I have a PC in my house where the SSD has linux and windows is on the harddrive. It only boots for league of legends and its fine.

Its slightly slower to first load and you’re only using it to play one game which loads into ram anyway. There is no reason not to.

Its not all nefarious. The bad is usually a byproduct of normal business usecase. Here there is little reason to hide ext4 and btrfs support just to spy on a few linux boxes.

Windows cant read ext4 or btrfs so I doubt they care enough to be sneakily trying to identify and read data on another partion.

a 500gb hard drive is like $30 thats nothing.
