Just find it funny that there's so many saying the game doesn't look good as if there hasn't been a ton of pictures of the game already.
A lot of people reserve judgment for final release versions since things can change. Respawn even gave people reason to hope that the resolution could still improve between the beta and release.
Even then, patches can still improve graphics post-release. Look at AC4 and COD for PS4. If you applied your logic to those games for PS4, then people judging those games' graphics based on release or prior would be very wrong.
And I find your statement funny, considering the opposite is usually used in defense of a game when people shit on it before release. "You're all criticizing the game when it's not even final yet. The devs still have time to work on it!" Not saying you're one of those people, but if both sides had their ways, no one could say anything about any game ever. Criticize before release and, "Your criticism is premature! Devs can still improve it!" Criticize after release and, "It's too late! Didn't you already see footage pre-release? Why are you just saying something now?!" It's really silly to complain about it. People will see footage at different times and choose to comment or not at different times.
