I’m way worse framerates, battery life overall performance with GTA 4. I really didn’t expect this as GTA 5 ran an extremely stable 60 FPS and only 10 watt battery drain. Even with the explosive bullets cheat and 5 stars not once did I see a frame drop. With 4 though, I had to drop it to 40 fps and still encounter occasional freezing with medium settings.
PC ports being awful was actually the norm back then. We PC gamers used to praise companies that released good ports, when it should be the bare minimum. Granted we still get crappy ports from time to time, even with big game releases that should be taken good care of (looking at you, Last of Us Part 1), but generally speaking, I’d say that awful ports are now less common than good ones.
