I just played Black Hole, Arabian Nights and Funhouse. Maybe it's not lag, maybe it's just the flippers do not feel responsive to me, like they are moving through molasses. I'm an old-school pinball player, between 1976 to the release of High Speed, I played pinball for several hours a day, several hours a week. My parents owned a roller rink when I was a kid. One of the things I loved about Williams pinball machines were how QUICK they were. None of the other machines (Bally, Gottlieb, etc.) were as quick as Williams machines. So when I play the Williams table, I expect them to feel like the real thing.
I have attached a video of one of my favorite old-school Williams tables, Space Shuttle.

Here's another one we had back in the day, Big Ben, going back to the 70s here.

You can see how quick the flippers are. Pull up a Ballys machine from the same era, how about Supersonic, another machine I played a lot.

I don't know if you can tell the difference in the flipper "feel", but it's not the same. You might or should see the flipper speed is slower on the Bally's machine. In fact, typically all the Bally's machines had a more laid back feel than the Williams tables.
I realize these difference are probably subtle when you are watching them on a video, but when you are playing the real table it's all the difference in the world. It can mean the difference between a great shot and a miss.
One of the tables I put a million hours on in 76 was Gottleib's El Dorado. It is pretty much the table I cut my teeth on.

We have an arcade by my house, and we still go play the real thing. Unfortunately, they don't have any classics, just the new Stern machines. I've found them to be not as reliable and as "tactile" as the older tables.

BTW, if you want to add me to your PSN friends list, my screen name here is my PSN name. Be sure I know who you are, because I'm EXTREMELY picky about who I have on my list. At 47, I don't want a bunch of kids.

EDIT: the more I think about it, the more I still think it has to be lag. I see the ball coming, and I'll miss it when I should make a shot.
