I am sorry to hear that all the issues you are running into.
I picked the resolution because its still less than half the height of my resolution and didn't think about looking at the avg of other games. For the lag we have found that the audio lag can be caused by lower internet speeds, we should have used a more compressed format than wav. for the loss of frames we have a issue on the movement that makes it non-pixel perfect that causes bg jitter, do you think that is what you are seeing? if not would you mind sending me a recording so I can look into it more.
