When was the last time you played a PC game and it worked perfectly "out of the box" without having to track down and install a million fucking patches, ini files, drivers, and other shit? I honestly can't remember, but then again I mostly play pirated games. Just a few minutes ago I had played Valkyria Chronicles for 4 hours straight when it suddenly crashed and I lost all my progress. This fucking game NEVER EVER crashed once on the PS3 and I completed it multiple times.
I never upgraded from windows 7, I only play mid-tier games like KSP or indie stuff like Street Arena. Haven't had any issues so far.
dunno why anyone actually upgraded to windows 8 or 10
Even on original games I had these issues. Valkyria is original and it seems to crash every time I play it for a long time. I bought the Tomb Raider reboot on Steam because I'm a fan of the series and that fucking game was literally unplayable on release and it kept having graphical issues (effects missing in fullscreen mode) until I got the second patch was out. Another game that I bought was Batman Arkham Origins and that one had several game breaking bugs, I remember I fell through the map, got stuck into a tower, and of course random crashing.
