#EXPERIENCING LAG PROPRESENTER 6 MAC WINDOWS#
Regarding Windows: I suspect Windows uses a different, ancient technique to draw the mouse cursor: sprites. All games and design apps use double buffering (or in some cases, triple buffering), otherwise incomplete frames would be shown.
#EXPERIENCING LAG PROPRESENTER 6 MAC MAC OS X#
Your statement “Yes, Mac OS X is less suited for gaming and design.” is false. The mouse itself does not lag, but merely the graphical representation of it.Ģ. If the assumption is correct, this leads to the following conclusions:ġ. After the next vsync, the back buffer is drawn. A new frame is drawn onto the back buffer, with the new mouse position. You move the mouse just after this is done. Here’s what I think is happening in the worst case:ġ. I’m assuming Mac OS X uses double buffering for graphics. Observation: when I quickly select text using the mouse, there is no lag between the mouse cursor and the selection of text.
Yes, Mac OS X (any version) is less suited for gaming and design.I’ve also heard that they are supposedly working on a solution. The problem has been confirmed by an Apple engineer. The problem is as well closely related to the cursor jumping issue that has alone been fixed in Lion thanks to all our bug reports. You can supposedly avoid the issue by disabling QuartzExtreme. The problem is caused by a bug somewhere at the windowserver level of Mac OS X, and not by a mouse driver. It still exists in Snow Leopard and Lion. The problem I’m talking about affects all mouse and touchpads since at least Mac OS X 10.4 Tiger. In ControllerMate, for instance, you can manually draw your own acceleration curve.īut it’s all pretty much useless as long as mouse movement is literally retarded, because it takes a lot of time for your brain to get used to it. The truth is, in Mac OS X you can change acceleration to whatever you want using many programs and techniques. I mentioned acceleration because a lot of people often confuse it with lag. The lag of a Mac OS X cursor is at least twice bigger than Windows’ cursor and yes, a human eye can surely notice that. * * * SmoothMouse, the long-awaited fix for mouse problems in OS X, has been released.įurther discussion about mouse lag continues on the SmoothMouse Forum.īy that I mean a delay between receiving movement data from the mouse device and rendering the on-screen cursor. The main problem of mouse movement in Mac OS X is not acceleration - it’s lag.
