I have an issue in the editor where dragging a selection marquee or rotating in the scene view port is slow and delayed.
It doesn’t seem to be a performance issue as it is still drawing at a nice smooth frame rate.
The result is a kind of weird delayed smoothing on any mouse input which makes things pretty difficult to work with.
I have reinstalled unity and tried loading several different projects to try and narrow it down.
Seems to be a unity issue as it doesn’t happen with input in any other programs, Maya and Photoshop all run fine.
I’m running on windows 7 under bootcamp on a MacBook pro retina.
I have this issue as well sometimes. It happens to me when the Game and Scene views are both visible, meaning next to each other. Like that Unity has to render the whole scene at least twice. The fps statistics are pretty useless because Unity doesn’t take that situation into account and only shows you the performance of the Game view.
Maybe that’s also the cause for your slowdown.
Hmm I don’t think that’s it. I don’t ever run with both views open… Just the scene view maximized.
Also tried installing unity under MacOs and the problem was not present. It’s definitely not a performance thing because it happens even in an empty scene with just a cube, and like I said the redraw of the view port looks like its running at at least 100fps it’s just delayed from the mouse input.
After some further testing it appears to only be affecting the mouse input inside the 3d view port. not the keyboard input or mouse scrolling in the inspector or project window etc.
seems like its handling the mouse input for the 3d view at a different level. like at the hardware driver level rather than the normal windows handler…
