Are you sure you are reading to me? This game in Windows on same machine: 1280x720 high profile = 40-60 fps. Mac version 1280x720 low profile = 15-20fps. I can to play on windows even to 1080p and low profile to 30-40 fps. MBPr can to play the most window´s games to 1080p high settings.

Anyway, 10.8.3, new nvidia drivers and same performance. Conclusion this port SUCKS. Even using wine I can get better performance.

Sure

Same machine, using FRAPS in windows, OpenGL profiler in Mac:

Bootcamp: 1280x720 Ultra details (Ubersampling off) = 40-60 fps
Mac: 848x480 Low details = 15-30 fps

Bootcamp: 1980x1020 Low details = 30-50 fps
Mac: 1280x720 Low details = 10-20

Bootcamp: 1980x1020 High Details = 10-20 fps

Par with windows? are you kidding?

650m of Macbook pro retina have twice of power than desktop 8800 gtx (minimun requeriments for 1280x720)

Besides:

In windows the game use full all cores and threads (4 cores 8 threads), Macos the game use 1 core 1 thread. I´m sure you are getting lower performance than windows, but you have the strongest solo card.

Come on, I don't believe it!

First: I can´t find FAQ for Mac version
Second: OpenGL run better in Mac than windows in this machine!, if there are problems with drivers, OpenGL would run better in Bootcamps.
Thirst: nVIdia drivers? http://steamcommunit...49037806757751/

Those are excuses, this game run poorly in Mac. Besides if there are problems with this card, why 650m is a recommended card for that resolution?

See you

Mac version sucks, if you think the game plays fine in your Mac, install windows and bootcamp, and you will see that 680MX can to do really.

Intel HD 4000 it´s between a 50% and 60% more powerful than XBOX 360 EXYNOS. The problem isn´t the card, it´s the game, Witcher 2 PC performance sucks!.

For example, Mass effect 3 same resolution and level details :

XBOX 360: 25-30 fps (Vsync off)
PS3: 15-30 fps (vsync off)
HD 4000: 40-45 fps (vsync on)
