Gfxcardstatus 2012 retina6/12/2023 Normally I would say the nVidia card just died, but nothing is showing this. But I think it did not update GPU drivers and I am unable to find pure GPU drivers on nVidia site just to test it. Today I reinstalled these CUDA drivers again and again updated them to the latest version with still the same result. It suddenly stopped over night and I am not aware that I installed anything (not even any appliacation) during that time between the last time I know for sure it worked (Monday evening) and the time I discover it does not work (Tuesday evening). So it worked with these drivers for almost 2 weeks without problems. I installed CUDA drivers about 2 weeks back. Any way how to distinguish this rather than to rely on gfxCardStatus? Any log that would make this clear? Any test I can run (Apple HW test shows "no problem detected")? Is there a way to see if the nVidia card is working? I suspect that even if the system is trying to switch to a discreet card it still runs on the Intel in reality. Only in heavy load it is obvious that it is slow (slower than it was). gfxCardStatus shows that the system switches the card and I notice no change. flickering or black screen when swithech do nVidia - nothing. But otherwise there is no visible flaw, e.g. But I tried to uninstall it and got the same result. Only one thing comes to my mind - Apple Java update. I do not remember installing something that day/night that could have broken it (in case it is a SW problem). I took another test and downloaded CINEBENCH to see the differences and sadly the results are the same if I switch to nVidia or to Intel and run the benchmark. But the performance is the same as running it on an internal Intel. I installed gfxCardStatus to see whether the card is being switched to run the game and it actually is. It took me several hours to find where the problem is and it seems to me that the nVidia dicrete card is not working. It ran fine till yeasterday when I fired up a game which was laggy and it was running fine before. use gfxCardStatus) to manually select it and see how you go.Having a MacBook Pro Retina. The best way for you to find out if the integrated Intel Iris Pro GPU is capable of supporting your particular monitor is to try Option 2 above (i.e. However, setting this up is more for advanced users. Use gpu-switch to effectively do the same thing as the gfxCardStatus application, but switch between the integrated and dedicated GPU for the next reboot without the need of booting into macOS and running gfxCardStatus. I would install the latest version first (v2.3), but if you run into problems then try version 1.8.1 followed by version 2.1.ģ. Please note that while the gfxCardStatus application has been a saviour for many countless users over the years, that for some models the latest version is not actually the best one to use. This also lists which applications use the dedicated graphics so you have more control. Use the gfxCardStatus menu bar application to switch between your two graphics cards manually. However, this actually enables the dedicated NVIDIA GeForce GPU by disabling the auto switching and does the exact opposite of what you want.Ģ. You can deselect Automatic Graphics Switching in System Preferences > Energy Saver. You have three options that give you some manual control over how the two graphics processors work:ġ. While this default behaviour is convenient and the best option for most users most of the time, as you have discovered there are times when it'd be better to bypass this. By default your MacBook Pro will automatically switch between the two graphics processors depending on how you're using your computer at the time.īy way of example, your MacBook Pro uses the integrated Intel Iris Pro GPU if you're typing a document or browsing the web, but will switch to the dedicated NVIDIA GeForce GPU when you connect an external display or play a graphics-intensive game - basically whenever the extra graphics performance is needed.
