berlin Posted October 10, 2014 Share Posted October 10, 2014 Hi, my laptop is equipped with two graphic chipsets the Intel HD4000 and the GT650M. OSX switches between these on demand, i.e. when using a text editor or preview it uses the HD4000, when launching "demanding" software like SketchUp or SimCity :) it switches to the GT650M. While the GT650M offers a better graphics performance it also decreases the battery range. While using AD I noticed the laptop automatically switches to the GT650M, even when no file is opened. Inkscape for instance just works fine with the HD4000. I was wondering whether it was possible to integrate a switch so that one could design whether to utilize the faster chip for better previews or the integrated one for longer battery time for instance when one is on the go. Of course the HD4000 is slower, but then again the 13inch non retina which apple is still selling as their entry level notebook solely relies on this chip anyway.

Staff MattP Posted October 10, 2014 Staff Share Posted October 10, 2014 I think you'd actually get a very similar performance from either chip, to be honest, as we only use the lightest amount of GPU time - my old MacBook Pro from 2008 worked super-fluidly... I'll look into setting the app to tell OS X to only use the integrated chip, but in the meantime you can install 'gfxCardStatus' and force it into integrated mode, if you fancy? :) Thanks, Matt Quote Link to comment Share on other sites More sharing options...
berlin Posted October 10, 2014 Author Share Posted October 10, 2014 Hey Matt, thanks for the quick reply. gfx.io was the first I checked, but as they write on their page, one should always contact the developers to improve the sitaution. Don't know if you looked into it but there is a nice article at Apple Dev( https://developer.apple.com/library/mac/qa/qa1734/_index.html ) about a parameter that one can switch in order to allow dynamic openGL switching . Anyway using gfxCard integrated only mode it works sweet as well :) Quote Link to comment Share on other sites More sharing options...
