Ok. So are you saying it doesn't select to use it rather than doesn't use it? Because if it has better performance when a discrete card is used, it must be using it, right? I'm a bit confused.Marco Raaphorst wrote:I can refer to my blogpost I wrote about this: http://melodiefabriek.com/blog/audio-gl ... eason-fix/joeyluck wrote:Ok good to know.

I'm debating exchanging for a 13" 2015 MacBook Pro 3.1 GHz i7. But I'm a bit nervous performance will still be poor... The Air Turbo Boosts to 3.2Ghz and the 13" MBP Boosts to 3.4 GHz (with a higher base frequency though).
[EDIT] But as people are mentioning, there is better performance when disabling card switching... Meaning the OS is then using the discrete card always, correct? So what does that mean if Reason has better performance under the discrete card, but isn't using the discrete card?
I'm asking about this because I'm wondering if that is why I get a little bit better performance from my 2008 MBP with an NVIDIA card vs. this new MacBook Air i7 with integrated graphics.
