OK, played me some today, and so far, yes, there are some weird frame drops, in really weird places also.
During loading the game, I got 1-3 fps.
During the 1st cut scenes, I was getting 166 fps. Then, 1 or 2 people would move into the cutscene, and it would drop 33, each time new people popped in for a little gum flapping. This went all they way down to 68 fps.
Weird for just cut scenes.
Then loading screen again, and another 1-7 fps, What the duece?
Then I started playing the game (I set it for max 120fps), and the gameplay so far has been hanging around 102-117. So, not bad at all, and not much fluctuation.
I havent gotten into a major foght with lots of people yet though. Based off the cutscenes lowering like they did when new people came into the scene, I bet THAT is where the drops will be coming from, when new people come onto/into the scenes.
But, so far, like I said, not bad.
10x better than mafia 3, even after 3 months and 4 patches for it, it still is worse than DH2 (which sucks, because I like Mafia and gunplay better than DH stealth style gameplay).
I will let you know if I find anything else weird, or where the frames drop.
