For me, the best browser on vista its UCBrowser, i received a update two weeks ago , fluid and stable,FF 52 feels slow using both at the same time.
My Windows 10 drive died,so i stay on vista until my drive dies
Overwatch runs on Vista fine, my cousin installed without problems,rockstar probably keeps support for gta v on Vista, at this point of his life i dont expect a major update like the crew with his new graphics,saddly vista support was drop, Battlefield 4 last UI Update works on Vista and let switch to Battlefield 1 on the game (i wish someone could mod the installer setup to make it run, 372,70 drivers add support to BTF 1 ,so , its possible run this game , ignoring the the old drivers and missing dll's )
