Nah I never update my windows lol. It's windows 7 anyways. For comparison, my laptop (windows 10) with worse, but similar stats (i5 9300, gtx 1050ti, 8gb ram, 500gb ssd) has none of these issues. In the exact same desolate spot of southsun cove I break 60 fps with it, while with my PC I can get 60 looking at the sea / horizon, but when I look at the island, 20 fps. I think you might be onto something with your own post tbh... Windows 7. Not hating, but need I say more? Yeah except for the fact that it was running well until this patch. Smh...
