Hello.

I bought the iMac 21.5 inch high end model (2.9Ghz i5 quad core, turbo-boosted to 3.6Ghz, 8Gb of RAM, GT 750m 1Gb GDDR5...). How will it run the following games under Mavericks?

- Minecraft
- Call of Duty 4: Modern Warfare
- GTA San Andreas
- Dirt 2
-Grid
- Metro:Last Night
- Bioshock 2
- Bioshock Infinite
- Borderlands 2
- Batman Arkham City
- Batman Arkham Asylum
- Doom 3

Please answer with what settings and frame rate I should expect from these games; thank you :)

And has anyone tested these games on Mavericks?

I've played Minecraft and it's smooth. But then, it's smooth even on a crappy Intel HD 3000. Minecraft isn't graphics intensive even at max settings.

COD 4: MW: Well, it runs smooth enough on a Radeon 6750M (30-40 fps at medium-high settings). You should be able to achieve the same frame rate at high settings on the GT 750M.

GTA SA will run smooth at max settings, because it's such an old game.

I haven't tested any of those yet. But however, you can check here to see the performance of games on the GT 750M: http://www.notebookcheck.net/NVIDIA-GeForce-GT-750M.90245.0.html

Note that the link here is for the normal GT 750M. The iMac has the much faster GDDR5 variant of the GT 750M, so you can expect better performance than what's stated in the link.

But are thoses game results on that site not from Windows, rather than running in OSX? And one more game; are you played Assassins's Creed 2?

Those game results are in Windows. You should be getting the same performance in OS X.

I don't play Assassin's Creed :(

I don't play that much games, all I usually play is Minecraft, FlightGear and NFS MW 2012 (via Boot Camp in Windows).

I played GTA for some time, but found it too unrealistic, and wiped it off my Mac.

Thats ok :) NFS is cool, is it possible to get it in the mac app store? And would that run in OSX?

Thanks for the help!
 
Everyone keeps posting the link to notebookcheck regarding the 750M. I have a question though, are those results based on the older DDR3 750M or the GDDR5 one that is in the new MPB's? If i'm not mistaken, the benchmarks on notebookcheck are for the ddr3 one.

I've read a few posts elsewhere, and even a mention on notebookcheck that the "rare" GDDR5 runs slightly better than the GTX660M and I've even seen some posts claiming it's on par with the GTX670M. Does anyone know of any benchmarks of the ddr5 chip?

Just look at the 660m. The 750m in the rmbp is clocked at 967/1250 with ddr5 (apple seems to disable boost). Notebookcheck's 750m is at (with boost) 1058/900 DDR3. The 660m is at (boost) 950/1250 with GDDR5. At best expect 1-2% better than the 660m.

Thanks for the info. That 1%-2% is pretty negligible. I use the 660m to get some benchmarks.
