This has the downside that it increases the Mac's power usage, and therefore decreases battery life. Normally the GPU in use is opaque to the user, so using an app such as gfxCardStatus is helpful to see what is happening.Īs a workaround, use the gfxCardStatus app to force the Mac to use the discrete GPU while working in Eclipse. ![]() You can force the Mac's graphics to switch between integrated GPU and discrete GPU using the free gfxCardStatus app ( ), or let OS X decide naturally depending on what apps are running. The MacBook I am using is mid-2012 Retina MacBook Pro - the integrated GPU is an Intel HD Graphics 4000 1024 MB. It seems that no, bypassing gfxcardstatus is still not possible. It also appears that the problem only occurs when the MacBook is using its integrated GPU, and it does not occur when using its discrete GPU. This problem did not exist in Eclipse Luna (4.4.2) it appeared in Eclipse Mars (4.5.0). Anything that causes a repaint of the editor, such as a change of window focus, will fix the problem. However the problem is frequent enough that it makes working for hours in Eclipse Mars difficult, as there will be frequent corruptions of the editor pane, meaning you can no longer trust what you see in the editor. This problem is intermittent: it might take 30 seconds of scrolling up and down to duplicate, or it might happen immediately. Scroll up or down quickly in a reasonably large file (say 400+ lines) then stop the inertial scrolling by tapping and holding on the trackpad. The problem was seen scrolling with the MacBook's built-in trackpad. Questions? Comments? Have a fix?

When done, quit Disk Utility and proceed with the OS X installation, migrating your data from your backup when the installation is complete. 2012 rMBP early 2012 Retina MacBook Pro (15') with 2.7GHz Quad-Core i7, 16GB of 1600MHz DDR3, NVIDIA GeForce GT 650M GPU (1G), and 512GB 6Gbps SATA flash storage ( gfxCardStatus was used to disable Dynamic Switching and force either the Intel Iris Pro or the GeForce GT 750 to run each app. Then select Disk Utility and use the Erase tab to format the hard drive. Therefore, if you are experiencing this problem, you can try first backing up your system and then restart with Command-R held down to load the OS X tools. Some of those with this problem have tried reinstalling OS X directly but have not seen much improvement however, some who have performed a full format of their hard drives and then reinstalled OS X from scratch have seen a notable improvement in the interface lag. You can also use the popular gfxCardStatus utility to customize which GPU is used and when. Therefore, go to the Energy Saver system preferences and uncheck the automatic graphics switching option to only use the dedicated GPU. When there is no demand for the faster processor the system will by default switch to the lower power Intel HD graphics, but this may also contribute to perceived lag. To conserve power, Apple provides an option to tap into the Intel HD graphics on the CPU or automatically switch to the dedicated Nvidia Geforce 650M GPU. OS X will create a number of temporary caches and hardware settings can be cleared using a general maintenance routine to see if they are affecting the system's performance or compatibility. If you own a new Retina MacBook Pro and are noticing choppy and laggy interface behavior, there are several things you can try: Furthering this notion, some who have formatted their systems and set up OS X again from scratch have noticed a significant improvement if not an elimination of the laggy performance, which suggests that the OS configuration is a major contributing factor to the lag being experienced. Some of those who have noted laggy performance on their systems have not seen the same lag on others, indicating that the problem has factors other than being simply a hardware limitation. ![]() It may be easy enough to claim Apple has a hardware limit it has run into with the MacBook Pro however, the poor performance is not being shared by everyone using the systems.
