Why are rendered Graphics so bad on OS X? Observations as a programmer.

Are you sure that this isn't a problem with upscaling non-retina content to a retina display?

Witcher 2 on my 15" rPro is pretty much unplayable for me, even at 1440*900 medium settings. Even after the latest updates.

Have you tried a SMC and PRAM/NVRAM reset?
When i have low FPS and performance on my rMBP then i do that and then it works nice! 😀

Unfortunately it's just poor drivers, the developers even state that.

Yes I'm sure. I'm not using a Retina I'm using a hi-res.

Sounds to me like vsync is somehow disabled on your MBP.

Or am I misunderstanding something?

No, it is not vsync related, vsync causes slightly diffrent, but simpler effect. I have spent hours testing this.

The new revision of OSX is also a bit of a help, but it's still noticeable.
