This issue affects all existing game runtimes (a basic Google search will show it), and as I mentioned, this is due to the way Android plays sound, even with OpenSL there is always a chance of lag, we are aware of this, and we are working to make some changes to get more speed and reduce this lag to a minimum possible.
I have not had any sound issues so far in unity although I am aware of latency issues from a "basic google search". It is the frame rate drop in fusion that is the issue because of how severe it is and makes the game unplayable. Unity's latency issues also seem more to do with the 3D side from what I have read.
I don't like unity over fusion, there is a reason I keep buying your products. What is frustrating is how long these issues take to fix without any updates and you are pushing people away from fusion. There are issues in threads that get ignored, or get told months or years apart that it's being addressed... What exactly are we supposed to do as the buyer when what we want to create can't be achieved because of an issue not of our fault? There are limitations of fusion but I'm talking about issues with fusion that shouldn't be an issue due to limitations.
What exactly is the reason why problems like this take so long to be addressed? Is the whole team working on F3 or is there other issues? I have 8 months worth of work in fusion on ONE game, let alone the countless others. It would be great to know something is happening so we can continue working on our games...
