Temporary UI Lag fix on Macbook Pro Retina 13 late 2012

[ChrisDB]

Hello there,

In Yosemite , I have massive UI lag , in mission control , safari with heavy websites , even in folders and settings , is unacceptable but I found a fix .

Instal AutoCAD trial from their website , run it than close it and that's it , the lag is almost gone . I don't know how this is happening , but AutoCAD seems to have a fix for the lag .

There is a massive thread on the Apple discussion board about this very thing. I don't understand, how could running AutoCAD fix the UI lag? I don't doubt you, OP, I just genuinely don't understand.

Can somebody please explain it to me?

Seems that AutoCAD and also 3d programs like Maya do this . Is def. a software problem .

If I remember correctly I heard about this very same workaround for choppy graphics when the first Retina MBP was released. I'm going to try it later on my rMBP, thanks for reminding me!

EDIT: Yes, I remembered correctly.

Unfortunately on my rMBP this trick didn't work. I'm back to Mavericks and all works well now.

It's because the program uses a lot of resources like RAM, in which case the OS would free cached/inactive/non-wired RAM. After you close AutoCAD, the resources are freed so the graphics performance picks up. This is similar to doing a RAM "purge" in the terminal.
