I didn't indicate there was anything missing. I also didn't indicate that crossover cannot use my gpu. I'm well aware that crossover can and does use both iris and the nvidia gpus. I also haven't been misinformed. I'm simply asking questions in this forum to learn more about how others users are using their Macbook Pro systems with regards to GPU capabilities. That is what they are provided for. Apple rarely releases significant updates for the graphics chipset. There are cards available for desktop apple products that can have drivers upgraded on a more frequent bases. Mobile GPUs are always more limited, on any hardware platform and by any GPU manufacturer. They are often throttled, overheat fast, and seem more prone to have issues with driver updates than their desktop counterparts. Nividia and ATI both write decent whitepapers on updates for chipsets like the 750 et al. Some of those improvements might be nice for the Apple mobile platform. I mentioned Crossover as an example, nothing more. I'm simply learning more about how others are using their systems for higher end graphics applications and whether there may be an option at some point in the future for consumers to receive more recent updates from gpu companies.
