Enable gpu in lightroom 5.7.1
If you don't have an external card (which I highly recommend - expensive and generates a ridiculous amount of heat), the CPU offloads a lot of the processing to the integrated graphics cores over the on-chip bus, without the LR acceleration-management overhead and external bus load.Īlso, graphics cards generate heat in proportion to what you're asking them to do. So if you are running LR with an external card and turn off acceleration, no graphics cores are used at all. If you have an external graphics card, the CPU turns off the integrated graphics (which is a rather powerful graphics multiprocessor in recent i7 generations). You're testing GPU acceleration on/off which would not take advantage of the built-in iGPU. This is what answers the question about whether one needs to buy a separate graphics card or can do just fine with the built-in GPU. performance using the iGPU (the GPU integrated into the CPU).

The question is really how to compare performance using a separate graphic card vs. I don't think this isn't really the right test. I think the GTX970 is adequate for LR and PS.

I feel no regency to upgrade the video card. I am running a GTX970 to drive a 4K and 2K display. I have a very nice home built computer and my video card is one of the oldest parts. Does it make it more enjoyable using the program? It does for me. Is it a game changer for producing great photos, no. As an example, when I am using the radial filter, the response of the filter when acceleration is on and off is obvious. On my system there is clear difference with some operations I routinely use. Works fine for me! And my 6 year old i7-3770's integrated graphics easily drives my dual monitors directly using two of the three built-in DIsplayPort drivers.Įxternal graphics cards are for gamers and gullible do-it-yourself computer hobbyists. The integrated graphics co-processor in current Intel i7s is more than ample for stills photography PP and watching movies, and saves you money and power/heat to boot. Try it without a graphics card then add a graphics card and you will observe no difference in responsiveness then return the graphics card to the company that sold it to you for a full refund if I am right. "Vulgarity is the eloquence of the illiterate". Lightroom makes no use of the graphics card.
