![]() ![]() Also secondary displays will not work in this mode. There are some applications that will not work, or will not work well if you select this mode. If you are using gfxCardStatus and you choose integrated only mode, will only run on the integrated card. Integrated consumes less power, while discrete consumes more power. The discrete card is the higher power card that has been added (by Apple) to a socket on the motherboard of your computer. The integrated card is the low power card that is built into the motherboard of your computer. It seems you have some of your wording backwards. Further pointers to mitigating hacks for the most common issues for badly designed and manufactured MacBook Pros in the past are listed also in the announcement of ceased development here: A complete guide for that would be here: GPU Problem. If it is the AMD RadeonGate dGPU for MacBook Pro 8,2, 2011, I'd suggest lobotomising the dGPU with software out of the system. So that option might be the part of this answer that comes closest to your question.įinally some precognizing: the point "because my discrete GPU has some issues" might need a more detailed approach. The newest version might not be the best choice for what you want to achieve.Ī seemingly similar desire as yours, avoiding gfxCardSatus, led to the development of gpu-switch The versions available have different options, abilities. Please note: these versions of gfxCardStatus are a fine example for wisely choosing which version to use. It is not the only option:Ī newer/forked version (its development also ceased now) would be Steve Show's forked gfxCardStatus. If your system is still usable.Ĭody Krieger's original gfxCardStatus is no longer under active development fot some time now. It might be possible with a hack or maybe even to cleanly force the appearance and availability of the choice you seek in SystemPreferences.īut for your alluded usage scenario gfxCardStatus is the best and cleanest option available. ![]() All the configs Apple seems to offer are more graphics power: force more dGPU and therefore force worse battery life. Only using hacks – like gfxCardStatus – it is possible to get into the state of forcing more iGPU and better battery life (compared to – sometimes badly working – "Automatic Switching"). So, in effect, yes, "Higher Performance" is the same as unchecking the checkbox in the first screen, that is, to force the dGPU. checked "Higher Performance" = defaults to dGPU not switchable to iGPU. ![]() Unchecked "Automatic Switching" = defaults to dGPU not switchable to iGPUĬhecked "Better Battery Life" = defaults to iGPU not switchable to dGPU checked "Automatic Switching" = defaults to iGPU switchable to dGPU.Influencing these settings leads to the following options: just a simple Java stub with demanding graphics or a badly written app). Depending on the version of the operating system or the application this request could be quite arbitrary (e.g. IGPU is used as default but anything requesting "real graphics power" leads to switching to the dGPU. The default checkbox you see without gfxCardStatus means: Once the GUI arrives the drivers for both iGPU and dGPU are available, full acceleration for both is available and the power management kicks in.įor graphics performance and power management Apple deems fit a rather simplistic scheme: On a Mac with dual switchable graphics (iGPU and dGPU) the general setup is as follows:īoot uses usually dGPU with limited, basic capabilities since the drivers aren't loaded yet. ![]()
