Frame rate issue with Geforce 750m on late-2013 15" MBP models

I have this exact problem, exactly the same machine!

Very weird - any ideas on it?

I will try your Card Status tool tonight and report back - agree, it sounds like it should be the other way round??

Cheers for bringing this up!

I have the same problem in most HL2 engine based games. This seems to be a NVIDIA driver issue in OSX but some rumors said that apple is next to release a new mavericks update (10.9.1) with some fixes in GPU drivers.

Hi lpellerin,

After a decent test I can pretty much confirm the same deal here.

I set the app to discrete (750M) and had much smoother gameplay at full resolution, with everything turned up to the absolute max. However at maybe 2 or 3 points so far It does slow down considerably - it seems that even 'turning around' and facing the other way at these points is enough to go instantly back to smooth (and vice versa).

Set to Integrated (iris) the game runs slightly sluggish with the above settings, however if I sacrifice a little resolution and some filtering/aliasing it is close to the performance of the 750M albeit slightly jerky. I do notice a frame rate drop at the same points which makes the 750M almost stop cold, however with the Iris it just keeps running fairly smoothly.

mgarces132 - I hope your right about the update - it seems as though this new MacBook Pro should be able to handle HL2 with ease!

Another thing I noticed - when running with the discrete card, the computer gets fairly warm - but the fan doesn't come on. However with the iris running, the computer gets quite warm to hot, and the fans run at full tilt. Nothing wrong with that as I understand it thats how the MBP's run, but it's interesting nonetheless.

Hi,

I have the exact problem in OSX except my problem is in Minecraft instead of HL2. I experience better FPS when I forced the integrated Iris, which probably means that the game itself is not graphic intensive, but the dedicated GPU is just performing subpar to our expectations. I truly hope there will be a fix for this soon. Please let me know if you have any solutions to this problem.

I have the same problem with HL2. But gfxStatus doesnt let me force my mac to switch to Iris anymore 😟

what to do?

And why have I spent so many dough for a machine that doesnt let me play a 10 year old game at a decent FR?

unhappy customer here

2.3 GHz i7 16GB

NVIDIA GeForce GT 750M 2048 MB

Same problem, using gfxStatus I set it to dedicated and EVERYTHING acts slow. scrolling threw itunes and iPhoto. Cant play league of legends. Apple please fix this!!!

Same problem. Actually when i first tried Minecraft i got 200-250 fps (NVIDIA). Then after some time i checked again and it was 40-60 fps. Now setting the card manually to Iris Pro gives me about 80-90 fps. Something is terrebly wrong. Tried resetting SMC without any luck.

Hope they fix this soon.

I have the Exact problem, fps is very unstable.
I use Professional VJ programs which runs great and steady over bootcamp but in Mavericks i get bad and unstable FPS.

Exactly the same problem. I'm a VJ (Visual Jockey), and i use Resolume 4. The problem is very clear Specially when i go on extended screen, my frame rates go as low as 20fps.

I also did a small research on the codecs:

On Photo-JPEG, which is CPU rendered Codec, the FPS is dropping in a very agressive way, 15 to 25 FPS.

On DXV, which is a GPU rendered Codec, the FPS is also dropping in a very agressive way, 15 to 25 FPS.

On H264, I am getting much better performance and the FPS is reaching up to 50+ FPS.

I bought 2 MacBook Pro Retina 2013-2014 with NVIDIA 750Ms, and i am facing the same problem on Both. They were bought for my Performance needs, and now i can not use them.

Also, the gfxCardStatus tool is not being useful.

I need a solution ASAP, as my investment is not giving me anything in return, and this is not Fair.

Thanks.

I have the same issue. Installed Half Life 2 today. Running late Macbook Pro with the 750M graphics card. Two areas so far has grinded the gameplay to a halt. Lowering graphics settings seemed to have very little effect.

Someone above seemed frustrated and thought this has anything to do with insufficient hardware. Rest assured that the hardware is certainly not the issue here. This computer has enough juice to run Half Life backwards and forwards at the same time. No, this is something else.

Drivers? Some other compatibility?

Any clues?

it is ridicolous slow. i do not use the graphic card for gaming i use it for rendering.

i dowloaded the free tool luxmark 2.0 http://www.luxrender.net/wiki/LuxMark and i noticed that the iris graphic cards is incredible fast compared to the gforce 750m

score for all

810 all
497 cpu
635 iris pro
149 750M geforce even the fun did not start 😀

I too am having this exact same issue. I've switched over to the Iris integrated graphics and it works nicely. However, this is an unacceptable fix. I wanted to play Half-Life 2 via HDMI with a controller on a television to show to my girlfriend, but now I can't as the integrated graphics will not allow HDMI to run. Half-Life 2 is running absolutely terribly with the GT 750m. I'm wondering if this is a driver issue, because this is unacceptable!

Yep. Half Life 2 with AA disabled and everything else on high runs very choppy in certain areas using the 750M on my MacBook Pro 15" Retina which has an i7 2.6GHz with 16GB. Running Yosemite 10.10.1. Installed latest CUDA driver as well from NVidia. Nope. Still choppy in areas. No reason this 10 year old game should run like this on such fast hardware. I also have noticed polygon artifacts and disappearing objects, etc. in the game.
