It makes the machine run much more smoothly, and removes any scrolling or keyboard or lag I experience in regular use. When I’m on the go, I want to optimize for long-lasting battery above almost all else.īut when I’m plugged in and charging the laptop, I always want to use the discrete graphics card. The solution is to use the machine’s discrete graphics card instead.īecause the discrete GPU uses more energy, I don’t want to use it when I’m on battery power. You may experience similar issues with your machine it’s not uncommon. It’s much faster, runs hotter, and uses way more power.Īfter some googling, I figured out that my lag problem is related to the laptop’s integrated graphics card. The discrete graphics card is the machine’s isolated GPU it runs separately from the onboard CPU. One is the integrated card, which is part of your machine’s regular CPU. Many people who read this will likely already know, but 15” and 16” MacBook Pros have two graphics cards. It’s not just the terrible keyboard (although that’s a big part of it), it’s also the consistent feeling of lag I experience whenever I’m using the device. Now that I’m used to the consistently excellent performance of my iMac Pro, using my MacBook Pro is an exercise in frustration. This includes modern 15” and 16” MacBook Pros.

It may have been introduced with the latest EFI firmware update released earlier for these systems, but luckily for those experiencing it the issue seems to stem from a fault in hardware-based settings for the system, and can usually be addressed by resetting the system's system management controller.Īpple has outlined how to reset the SMC for these systems in a knowledgebase article, which for Retina MacBook systems are the following steps:

This problem appears to be a hardware-based issue, as it happens not only in OS X, but also for games running under Windows in Boot Camp. However, it appears that the problem at hand is with how the system is handling this switching behavior, where it will switch back to using the lower power Intel graphics and therefore not be able to manage the demands of fancier games. Usually when systems drop to low frame rates it suggests they are being overworked for some reason and are struggling to make the computations necessary for smooth gameplay, and as a result will usually be relatively hot as the graphics card is taxed however, in these systems this is not the case and in testing some users have noticed that various monitoring tools show the system at a relatively idle state, suggesting the system is not being taxed much and instead is just not performing the computations at hand.Īpple's 15-inch Retina MacBook Pro systems ship with two graphics cards (a discrete Nvidia Geforce GT 650M for graphics intensive operations and an on-board Intel HD 4000 GPU for standard everyday tasks), which it switches between dynamically to get optimal energy savings and increase battery life. While at first launching the game will show the expected smooth performance, it may suddenly drop to a very low frame rate and be essentially unplayable. Some Mac users are finding that some of the latest MacBook systems from Apple are sometimes showing drastic drops in graphics performance, which are particularly notable when playing graphically intensive applications like video games.
