Enabling NVIDIA GPU for Adobe Premiere Pro in Surface Book 2

I've really been enjoying using my Surface Book 2, but it's Adobe Creative Cloud performance has been terrible. In Adobe Premiere Pro and Adobe Media Encoder, hardware acceleration (GPU) options were all disabled, which means that doing things like encoding video were being done on the CPU. My 15" Surface Book 2 has two GPUs: an integrated Intel UHD Graphics 620 adapter, and an NVIDIA GeForce GTX 1060. It seemed to me that Adobe products were defaulting to the Intel driver, which isn't able to be selected for hardware acceleration.

Fix: Adobe Premiere Pro CC plays clip previews too quickly

If Premiere Pro is playing clips back too quickly, check your Audio Hardware settings. If I set my Default audio input to "Microphone (Rift Audio)" (I have an Oculus Rift connected), playback is about twice too fast, and I can't get play it at normal speed. If I set Default Input back to "No Input", playback returns to 1x real time.

I hate this stuff.

Adobe Lightroom 4 DNG performance increase test

Earlier this month, Adobe announced that there would be [three upcoming improvements](http://news.cnet.com/8301-30685_3-57371809-264/adobe-offering-new-reasons-to-get-dng-religion/) to the DNG camera raw "standard" that would improve performance. I've not historically converted my RAW files to DNG, but performance improvements would certainly be a big factor in a decision to move to that workflow. I don't know whether any of the announced improvements have actually made it into Adobe Lightroom 4, but I the upgrade from version 3 to 4 last night ($79), converted some files to DNG, and ran tests. Navigation and editing was as sluggish as ever on my 12-core Mac Pro (with plenty of RAM)—I couldn't tell if there were improvements when working with DNGs. Then, I did some exports to 1920-pixel JPG files:

**Test 1: 28 ARW raw files from Sony NEX-5N** ARW->JPG, 2010 Process: **52 seconds** [ARW/DNG]->JPG, 2010 Process: **40 seconds** DNG export **23% faster**

**Test 2: 28 CR2 raw files from Canon 7D** CR2->JPG, 2012 Process: **62 seconds** [CR2/DNG]->JPG, 2012 Process: **43 seconds** DNG export **30.6% faster**

Here's the CPU graph for the export process. You can see the clear improvement in CPU utilization in the DNG export.

It does seem that there are real reasons to convert raw files to Adobe's DNG raw format. If Adobe continues to improve DNG performance, I'll likely move my workflow over to DNG conversion upon import.

I love Lightroom—it is my photo organization and processing app of choice—but in general, Adobe Lightroom 4 feels sluggish, and it took as many as 6 seconds to move between Library and Develop modes (inconsistent, presumably due to caching). No interface move should take 6 seconds on this computer. I hope there is a performance update in the near future that deals with the poor performance.[^1]
