I started using bluetooth passthrough recently and have become very interested in getting my wiimotes to work on dolphin as faithful to the original hardware as possible. I have been playing Super Mario Galaxy 2 and been very happy with the performance of bluetooth passthrough (when my adapter is not acting up) compared to the regular wiimote support.
However, SMG2 doesn't have much in the way of IR pointing aside from collecting start bits, etc. so I was not bothered much by the pointer movement lag, although I did find it a bit off. Just for kicks, I played a bit of the balloon shooting game in Wii Play and that's when I noticed that the lag is significant. I immediately turned on my real Wii and played there and could see that the IR movement was more crisp and faithful.
Both the Wii and the PC running dolphin are connected to the same TV, so even if the TV is adding some picture processing lag, it would be doing it on both. In fact, the video output of the Wii is passing through an external analog to digital converter that allows for an HDMI connection to the TV, which could be adding lag to the video from the Wii itself and yet gameplay is less laggy. I tried using USB 2.0 and 3.0 ports. I always play in exclusive fullscreen mode and tried playing with and without vsync. None of this seemed to make a difference.
I would say the lag is not game breaking but does affect performance so I'm curious if this is to be expected or if perhaps it varies with BT adapters (mine is Kinivo BTD-400).
I have a Wii BT replacement module on order to wire it to USB and will be able to compare soon but if anybody has experience in dealing with wiimote lag, I would appreciate some feedback.
PS: Whoops, I meant to post in the controller sub-forum.
