You might already have sussed this out, but the developer and EA are trying to convince everyone that Hardline won't have a launch as comically awful as.
"Stability has been one of the largest areas we’re focusing our attention at Visceral while developing Hardline," Glosecki says. "I think we can all agree that Battlefield 4’s stability at launch was less than stellar. In order to address stability for our game at launch, we’ve had the game up and running in the multiplayer environment for the last two years with both the development and quality assurance teams playing in daily matches."
The game's two public betas will also have helped the team identify issues, Glosecki points out, and Visceral will set up a version of Battlefield 4'sin order to test out new patches and changes before they make it into the full game.
also covers some of the graphical options players will have access to on PC, and responds to some common criticisms that popped up during the open betas. It's worth a read if you're looking forward to Hardline.
