Does inventor utilize gpu power

[Anonymous]

I was wondering if the gpu of a computer can help with the rendering. If it does would dual gpu help the performance

Inventor does not use the gpu for rendering, nearly everything in Inventor seems to be cpu bound. There are other threads detailing this more around the forum.

That is not the case. Actually all rendering in Inventor have to go through GPU, while in most cases it involves both CPU and GPU, e.g. Inventor will simply not be able to work without a GPU hardware. For a typical modeling workflow (extrude, fillet, etc) CPU is responsible to compute how the geometry will be and GPU is responsible to render the geometry with the specified appearance. There are more extensive GPU usage in certain env such as Studio, Stress Analysis and HSM. If you're talking about GPGPU that is a different topic, that is not something used in Inventor so far as I know.

Inventor actually utilizes GPU in several cases, such as MSAA, Shadows, Reflections, Image based lighting, all these enhanced effects are implemented based on GPU, however, it may not meet the GPU peak when using these features, thus you may not see the difference between different level GPUs.

Another aspect is for large assemblies, even just orbit and zoom the large dataset, Inventor also leverages the capability of GPU. But the performance difference between low level and high level GPUs still depends on the dataset structure, not all dataset can show the performance difference on these GPUs. I suggest always considering GPU as an important factor to performance.

For dual GPU, I think it may be beneficial to the large assembly case as I mentioned above, but it hasn't been proved yet, we could do more experiment and let you know more information when we have.
