There are a couple of reasons why there could be a discrepancy here and, depending on which console you game on, there might not end up being a difference in file size between versions at all. For starters, that 105GB file size initially reported came from developer Rockstar’s own posting of the PS4 Pro box are for Red Dead Redemption 2. In other words, if you’re gaming on a standard PlayStation 4, it’s possible the download size might be closer to the one currently listed on the Xbox site. Then again, as far as we’re aware, PlayStation doesn’t bother with different file types/sizes for different versions of the game. In other words, it’s possible everyone has to download the 105GB file on PlayStation and, if you’re gaming on Pro, you’ll be taking advantage of all that extra data in the form of better graphics and whatnot.
