I am running a Windows laptop with a GT 740M and it's actually impressively responsive and fast. A cube and sphere would render almost instantly. So I wonder if there is another issue causing you slow rendering speed? As an example, the video at
http://vimeo.com/87048593 was doe on the laptop - and will give you an idea of the render speed (it's the Modo plugin - but will be rendering the same speed a Octane Standalone). Also, what Cuda drivers are you running? Are there any other apps running in the background which might be also using the card? Can you post a screenshot of Octane Standalone rendering - so we can see the memory uses, samples per second, etc pls.

hi, you can try with this little utility:
http://gfx.io
in theory, if you switch the gpu to "integrated only" , you can leave the gtx 640m only for octane

You then go on to show us a little table where you state (and I quote) - 3.0 & 3.5 = NO LIMITATIONS.
There is no mention of the amount of cores required.
What I am now hearing is that contrary to what we (Otoy) state, some cards don't apply to these rules and, oh. best not run it on a laptop (I am using a 1 year old Apple iMac)
Some advice... At the top of you Hardware requirements, I think it might be sensible (and responsible to your new users) to state - This software will not work very well on laptops and the majority of Apple iMacs.
That FAQ isn't misleading. There are indeed no limitations in Octane for 3.0 & 3.5. We don't state anywhere how fast it's supposed to work.
You can perfectly run Octane on your laptop and everything works. Not all GPUs are created equal. Otherwise NVIDIA would just sell 1 fits all card...
cheers,

So you don't agree that a little extra advice to those moving to Octane, perhaps stating - The ratings supplied by Nvidia are purely for compatibility but are no indicator to actual performance.
I am in no way criticising your excellent software. And I think if you stop for a second you might see that is not my intention and my suggestion is actually a good one.

liquidengine (& other mac lovers)..consider the fact that macs are not the most powerful computers on earth..- their focus is on asthetics & ease of use. - it doesn't matter from what standpoint You're going to look at it..it's the same. Take the pill & swallow it & start to think..
why do You even consider that nice computer (iMac) with Mobile parts to be fast? it's not the power tool..it's nice decoration. (I'm not MAC hater, do have some Apple devices, but hey..) diferent purpose that's all & noOne to blame here.

The best option would be build a box dedicated for work..not a piece of decoration.
Please try and keep it proffessional... this isn't Facebook
I am well aware an iMac was built to cram as many components inside it pretty shell as possible without catching fire. However I have to use Mac for work and I chose this particular model after using the link on the Octane site. These are the facts.

Thanks for trying, but that only works on macpros.

I have been playing in Octanes settings to try and ease my pain...
I have found that reducing the samples to 10 speeds things up massively... Once I have a good composition then I can ramp them up and let it work whilst I do something else.
If there are any others out there with a low end card, this could help. (Surprised the forum pros didn't think of that
Thanks for all your input guys, and think about what I said about that disclaimer.
Over and out.

Have you tried setting the Render Priority to low? A mobile class GPU with lower RAM is really gonna slow down trying to render and drive your display at the same time. Render Priority controls the balance between power going to the render and power going to the display. Setting it to Low will give more power to your display and make Octane more response while rendering.
