P: GPU & Multiprocessor acceleration

Pathetic that this was open over 2 years ago.. and still LR5 has no GPU acceleration! and still is slow as &$/*"

From my understanding, Invida has application that are developed to leverage the power of the GPU to speed up some specialized serial tasks. With the progression of resolution in cameras ie.. Nikon D800 and high megapixel, medium format cameras, computer hardware seems to lagging behind in all but the most cutting consumer accessible machines. Building Lightroom to take advantage of already present hardware, can lower the hardware barrier to performance entry, for much of the consumer market. My computer was built on a core i7 platform, 12GB ram and SSDs, and struggles with 40-50 mp raw files. If progressively higher resolution is the future in multi media, and hardware is the bottleneck, we need to find alternatives to achieving consistent and reasonable performance with current technologies.

as I posted in another thread, if you actually disable modules that you don't use, - and we're not talking "hiding them" from menus here - you may significantly increase lightroom's responsiveness. It's no GPU solution for things like Capture One offers, but it definitely helps

I just updated to 4.4 and used it for a day without any modifications and it had zero improvement over 4.3 in regards to performance and was in fact significantly slower than what I had grown used to with my modded 4.3.

creating a "disabled modules" folder and moving Book, Layout, Print, Slideshow and Web .lrmodule files allowed me to again get back to a proper and snappy "for lightroom" perfomance.

Note, if you need these "features" then you're crap out of luck from this benefit. But I don't need to make books or print or make web junk from lightroom - i use it to catalog images and metatags, make corrections and export the images needed used for production in the software built for production - whatever the task may be.

Why won't you use experience of Premiere Pro CS6 and Photoshop CS6 developers? They made a successful work around using GPU computing power to speed-up their software.
Problem of Lightroom is that it could me many times faster, but it is not so.

Lightroom uses less than half computing power of PC because it doesn't use GPU - it is not a solution, it is a PROBLEM! And result of this problem is slowness.

GPU with its very fast RAM waiting for lightroom to use it!

I would expect Adobe to keep on improving performance of their products by, for example, making better use of GPU capabilities, so I think this request rather pointless.

and the difference is? both take an image and render it.
Though it behooves me to surmise then that if it IS a rendering engine issue, and adobe used two different rendering engines, why reinvent the wheel - yoink the photoshop engine that has the gpu capability and stuff it into lightroom - and add the "enable / disable option" for those who want or must have software rendering.
Lightroom is supposed to be awesome with photos. It's not. It's slow. Has been since day one - gets better, but I can render a 200" 2gig illustrator file in photoshop by the time I'm done "importing" 1000 photos @ 1:1 preview.

From my experiences Lightroom (LR) 4.1 is still not optimized to the fullest. Increasing LR 4.1 cache to 50GB was a big help. No other graphics/video intensive application that I have uses the resources like LR 4.1.

NEF files converted to DNG in LR 4.1 can take up to twice as long as the NEF files to load in the library and development modules. The DNG files also take 1.5 to 3 takes longer to load in 4.1 vs LR 3.6.

Although LR 4.1 is much better than ver 4 there is still a delay when using the sliders in the development module that is not present in the LR 3.6 with the same files. DNG more so than NEF files.

Win7 x64 OS
Nvidia GForce 9500GS
2 - 1.5TB HD: OS on one, LR and photos on the other.

Who teaches you guys how to handle customer recovery efforts?

But we're talking about Lightroom here, not Photoshop.
