The GPU is used in photomerge features?

I was wondering if the GPU is actually used in photomerge features? Because I'm not convinced that it is.

I have several available graphics processors to test low-end consumer (£25) maps to maps of mid-late Professional workstation (£450). I would really try a high-end gaming card... but think I'll give cela a miss as I don't have access to one.

In running tests, I noticed a difference in certain functions, some quite noticeable, especially with the GUI / answer image between the cards, so all is good there.

However, what I noticed is not a very big difference, if any, in photomerge features. Average processing times are the same, regardless of what the card is used.

The GPU acceleration is enabled by the way.

And here's the killer: if I disable the GPU acceleration, I get the same result (LR is restarted between changes BTW).

So so this is my conclusion. I find a bit strange if it has not been used. I thought that something like mathematically intensive as the fusion of images would be ideal for a GPU.

Someone at - it care to comment?

According to Eric Chan, the GPU is used exclusively in the develop Module and Photomerge isn't really the develop Module

Notes for Lightroom CC GPU (2015)

If I'm things understand properly, it would not help with photomerge anyway, which probably requires CPU rather than the GPU.

    Hi all

    I use after effects 14 CC, but I can't use it with the GPU (it uses the CPU). How can I solve the problem?

    (Use the CPU is not the best way to work with AE).

    Note that your card will be used for all the features of GPU - but the 3D rendering acceleration traced the beam - requires a Nvidia GPU. This is a deprecated feature that you don't need to worry about anyway. There are a lot of better alternatives to the use of 3D in After Effects, Cinema 4 d, including the who now comes with After Effects:

  • Tecra M4 includes memory shared for the GPU

    Hello

    I saw a great offer for Tecra M4 tablets. The only thing is that the GPU has only 64 MB of RAM. But I don't want to run the Advanced (or premium) version of Vista, including Aero.

    So, my question is, the series M4 includes memory shared to the GPU? If this is the case, then I can increaes the RAM from 512 MB base at least a 1 GB and the GPU can use part of it and therefore to run Aero.

    Also, I suspect that the versions of M4 offer have sub-6600 NVIDIA GPU, they would still allow use of Aero, assuming that the shared memory is possible?

    Thank you

    AFAIK the graphics cards on computers notebooks Tecra M4 is not shared memory and you can't change the video RAM.

    I install the first CC 2015 Pro and After Effect CC 2015 to 2013 with the graphics card AMD over-pants D500 Pro Mac, I can set GPU rendering in Premiere Pro, but impossible to define in the After Effect, only can use the CPU in the preview of the setting, how can I do?

    AE uses only a few NVIDIA CUDA enabled cards to speed up rendering drawn with RADIUS. This feature never quite worked, with disabilities masks and effects on layers 3D, and NVIDIA has changed the direction of their development of this technology for the Ray-traced rendering feature is is more developed by Adobe. They are working on another technology to use the GPU, but it is not yet available. There is nothing you can do to enable the GPU acceleration, unless you have a compatible NVIDIA card.

  • After using the GPU effects

    Szalam, if possible, I'd like some information in what concerns this topic because I'm having a moment a little hard to get my head around how After Effects uses the GPU in some situations.

    For example, I have a comp UltraHD quite complex with a group of layers 3D element. Because we work closely with the 3D with element layers, we have the rendering engine in After Effects "3D Classic" on. Because I'm using a GPU K4200, I'll just follow the advice of Adobe and use the CPU for any trace of the rays since the K4200 is "unsupported".

    So now that I'm assuming that After Effects will do all THE processing of treatment on the CPU - with the exception of the work of 3-d element, which will be done only on the GPU, correct? Then now, I guess as long as I "simultaneous rendering of several images multiprocessing" something sensible (i.e. leaving 1/4 or preferably more like 1/3 of the available RAM to non - After Effects-related work and not hungry processors), then After Effects will try to max-out the processors as much as possible for everything except the item in 3D work (which will be hopefully out the GPU max). Is this correct?

    Is it interesting to use in load/no tested (for example the K4200) GPU to accelerate the raytraced render engine in this scenario (i.e. 3D only in the model elements are 3D, element, cameras and lights 3D layers), or is it better to leave it on the CPU and leave the single GPU for 3D element?

    Thanks in advance!

    Right. Your scene does not all the layers using the ray traced in her rendering engine at all, so leave it on Classic 3d is the best choice. The new version of the item has "drawn with RADIUS' shadows and whatnot, but which is unrelated to converter traced to obsolete radius of EI. EI raytraced render engine is essentially an effect pressing the Optix of NVIDIA GPU library. It was just to add depth to layers. People are often confused and think that turning traced to the rendered RADIUS on would hire the GPU to make this, but the only thing he never accelerated has been traced to the RADIUS effect (which has very few people have already used).

    Pretty much, Yes. There are other potential bottlenecks (if you use images out of an external device with a slow connection, for example), but it's like basic things will be.

    Your scene, as you describe it, does not use the ray-traced rendering engine at all. The ray-traced rendering engine is just a way to add depth and dimension to natively layers in AE. Given that you do not use this feature, by turning your comp to use the rendering engine raytraced won't help what whatsoever and, instead, plu cause lead the times.

    But you can feel free to test yourself. Try a rendering with the standard rendering engine and with the renderer raytraced lit. See if you can see differences.

  • T430: Cannot change the GPU using the NVIDIA Control Panel

    Hello world

    I recently bought a T430 including a NVIDIA NVS 5400 M. games graphics card (for example, Max Payne 3) used to run fast, using the NVIDIA GPU. Today, I tried to play a video game once more (after having not played for several weeks). Unfortunately, my OS (Win7, 64-bit) assigns the GPU from Intel, resulting in a much lower speed. Using the NVIDIA Control Panel, I can't change my favorite GPU (changes will not be saved). I already run a update of Lenovo and installed the latest graphics driver (296.88), which resulted in no improvement.

    When you start a game, I can choose my graphics manually, but I would like to configure some general settings using the control panel.

    Do you have any solutions?

    Thank you very much.
