I pulled the latest commit for the follow camera, but I'm still getting the jittering issue others have reported when using it at low resolutions (480x270, 640x360) it isn't until I get to about 960x540 that it starts to smooth itself out. The lag is still there at the higher resolutions, it's just not nearly as noticeable
After digging into this for much of the morning, I've narrowed it down to being present when using TiledMapMover. Using a regular mover results in super smooth camera movement, using the TiledMapMover is very jerky. I see a commit to TiledMapMover a few days ago that was to address adding subpixel movement, but it was reverted a few days later.. not sure what that's about.
I've been unable to narrow down the problem further, or fix it... I'm giving up for now and hoping someone else can at least chime with with ideas.
