Hi Geoffrey I updated my GTX1060 to 376.09 yesterday. There's no need to uninstall the old driver first if you do the update using the 376.09 updater executable which you can download from the Nvidia website. When you run the executable, if you select Custom install, it gives an option to do a clean install and completely remove earlier drivers. You also get options not to install the GeForce stuff and 3D rendering components. It's very simple: not like the old days of uninstall GPU driver, reboot with display in VGA mode, install new driver, reboot etc. DR ... View more

Many thanks Melissa I processed a few more images with 375.63. I didn't have one instance of the image tearing into squares, so it seemed pretty stable I've now done a clean install update of the GPU driver to 376.09. Just opened the first image, and made a few edits and it too seems stable. I'll do a few more over the weekend and report back to say if it's still fine Thanks again for your help DR ... View more

Hi Melissa Just to update on this: I'm still using 375.63 I've done a couple of processing session now with GPU acceleration enabled. Only 2 images per session. Each session I had LR open for about an hour - doing some file imports and cataloging stuff. In the first session, the very first image I opened in the develop module tiled immediately on opening. It split into a grid of 8 equal sectors, Then quickly reverted back to normal. It was little more than just flashing into the tiled state and back out. That was the only time I saw any tiling in that session. In the second session it's been fine. Not even flashing into the tiled state. I'll keep working with the 375.63 driver installed to get confidence that it's viable. I don't want to change something that's working regards DR ... View more

Hi again Melissa I enabled the GPU and just did a very quick test with a couple of images 1st image: As I started to move the exposure slider the bottom right quarter of the image tiled very briefly, just flashed the tile for <1s. I zoomed the image to 1:1 and back to FIT, no problem. I pushed the clarity slider around no problem 2nd image: I did the same operations as above, no tiling observed. I'll process some more images this evening, with GPU enabled and see how it goes. One way or another I'll leave a comment to say if 375.63 works now or if the tiling issue is still there. thanks ...

Hi Melissa Thanks for the quick reply. After I found that v368.81 won't install with my GPU I've not tried to run LR with GPU acceleration enabled Windows device manager says I have 'Driver version 21.21.13.7563 dated 21st October 2016' I guess this is 375.63 in Nvidia's notation I'll enable it and see if I still get the tiling issue. From what you say above, it might be fixed. I see Nvidia now lists v376.09 as the latest driver for my GPU / Win10 64bit / UK English. I'll stay away from that one if LR GPU acceleration works fine with 375.63 I'll check it this evening thanks ... View more

...then I found the newest driver supported by LR6 is not supported by my GPU as the GPU is too new. So still stuck using LR6 without GPU acceleration. Come on Adobe, catch up with Nvidia. ... View more

Melissa Many thanks for your advice. I've downloaded the older driver from Nvidia. Now it's just a case of getting round to installing it, or waiting for Adobe to catch up with the drivers. ... View more

Hi shutteman. Many thanks. The plot thickens! My PC is quite new, the GPU driver has the same install date as the date I set up the PC. It seems the change that started the 'Rubik scrambled squares' problem was the update from LR6 to LR6.7 on my system. I'm pretty sure I've been running the same GPU driver with LR6 as with LR6.7. When I was running LR6 with GPU enabled all the time, I didn't get this problem. It was only for a few days, but I think if it was going to trigger, it was long enough. It's a small sample and not a real test, but LR6.7 is looking like the suspect to me. regards DJRandall ... View more

Many thanks Geoffrey@Sydney. It's nice to know it's not my PC or GPU but looks like an Adobe problem. I used LR last night for a couple of hours, with GPU disabled, and didn't get see the scrambled image problem. I'm now wondering what triggers it. It seemed to be worse after I'd opened an image in Photoshop Elements from LR and then reverted to LR. But that might just be coincidence. ... View more

Many thanks for the suggestion. I'll give it a go. It's not something I've tried as it seemed to be fine as L6, it's only when I updated to LR6.7 the problem started. ... View more
