Yosemite / mac mini

OSX Yosemite performance on a mid-2010 mac mini (NVidia 320M) reminds first 10.0 version : text rendering is 3 times slower (slow redraw when resizing windows), OpenGL is 2 times slower, and user interface test is 10 times slower ! Also opening windows (files listing) is slower, while the new UI theme shouldn’t require more power (it should be faster as it is simplistic – Googlish / Windowish -, without all previous refinements that ultimately landed into Mavericks, not mentioning still non fixed firewire disks sleep issue and trim issue).

Then Apple may use some new OpenGL 4 only APIs for Quartz, while older macs only support OpenGL 3.3.

The new mac mini have half the CPU cores than previous ones, do not allow adding RAM, and only provide an Iris graphics chipset (Iris Pro would have been at least required). Also new imac’s Nvidia 750M graphics card is old.

We now then have to either buy a retina imac ($2500) or mac pro ($2999), or wait for upcoming Broadwell based hackintosh (that will offer same performance for half power requirements, and then will allow smaller enclosure). Also Intel will release an updated Iris Pro.

We then want Scott Forstall (OS features and design), Jon Rubinstein (hardware leading edge with custom processors – should come with A8x) and Bertrand Serlet (Snow Leopard) back, as new team really isn’t talented (except iPad/iPhone hardware engineering).

Bioshock Infinite is available at discounted price (EUR 25.99) at macgames.fr. While not officially supported on Nvidia 320M chipset, it seems working well. Moreover using new Mavericks free OSX update, performance may be even better (then we may not need the new $2999 mac pro and keep the old mid-2010 mac mini – very silent and power efficient with an Intel SSD).

Aspyr reported Bioshock Infinite’s performance problems on Mavericks when using Nvidia graphics cards with high settings.

UPDATE : the game indeed runs fine on a mac mini mid 2010 (8GB ram, 320M, Intel SSD) with default low settings (sets textures to very low) at 1280×800 resolution, and still looks good (providing you don’t look close to some textures – it however keeps nice lightning effects). Using custom mid settings (medium textures level) we get more detailed textures while keeping a playable game, however the framerate stutters (pauses) regularly, which may be due to the Mavericks/Nvidia bug.

As supposed, Deus Ex Human Revolution should work with Nvidia 320M as stated by Feral at their Facebook :

Many unsupported cards will run the game, but with a bit of stutter, so we understand that you’d rather see for yourself.
If you meet the other specs, the game will work on that card. The only reason we don’t “officially” support it is that there is still a little bit of stutter, and we want all officially supported machines to have perfect performance.

The game is available through the Mac App Store (39,99 euros, 15 GB).
