Does this mean that the higher the passmark the better the rendering performance.
As a general guide, yes. However some hardware such as some of the Radeons may report a higher Passmark than an NVIDIA of similar specs (although hard to tell), but do not do quite so well with Lumion, so it is a general guide only. We also try to collect Benchmark results from user PC's, see attached.
Rendering performance is affected by the scene complexity and detail and effects, the GPU, a CPU that does not bottleneck the GPU, and good quality and performance hardware that responds the best to the current demands of the user in real-time and in rendering.
The 660Ti has more cores than the 760, 680 has a lot more. There are 3 key things for GPU's:
1. number of cores
2. amount of VRAM, the more the better to process scenes with more textures or larger textures
3. bandwidth supported
4. quality of the brand.
Overclocking will increase GPU performance, that may have (some) direct impact at time of render.
True, GTX 760's are new.
Everything will of course depend on budget, but also consider the marginal cost for the next product up. It may give greater longer term benefit. In most cases these are business decisions that reflect your decision to invest in Lumion, the difference may be doing a job just that bit faster, better or more often etc etc.
The 680 is still a good beast, but as its now an older version, I would have thought you might be able to purchase for less than a say 770 or even 760.
In my view the 770 does not have the comparative performance, the 780 is close (bang for buck) in performance to the Titan.
I currently have a GTX660. It performs fine, but it's an interim GPU. Lumion never crashes. Render times are render times; they depend on a wide range of factors and there are some things that can directly be managed within Lumion to help with those as well.
Hope to see you soon on the forum, posting great images and video animations made with Lumion.
