I've played on PC since release day then moved to ps4 recently
the meme is HVS lived up to their standards so memory leaks and framerate issues for most, patch delay until i believe tremor or tanya. all this shit drove people away to consoles
community at first was proportionate as consoles, not as big but the game was still decently popular:

the latest rise in players may be because steam sales / key shops where the game is $10 and KP1 is $3
I hate KP2 not being released on steam but makes absolutely sense from NRS/WB point of view: they failed PC, people moved away so all the hassle of realeasing not disk locked content to a desert is antieconomic
too bad, game on steam is visually astonishing, less lag due to less wireless players and maybe a couple of fixes away from the remaining issues
guess we're stuck with PSN+ subscriptions
