I was interested in seeing if I could benefit from GPU support in 8.4. I was not ready for the issues I ran into and potential serious recovery issues. My real problems were with Nvidia software more than LR not recognizing my adapter.
I run a Dell XPS 8700 with 16GB of memory on Windows 7 SP1 64-bit. It comes with a Nvida GeForce GTX 650 Ti display adapter. The latest version of the drivers support the specs listed on the Adobe GPU Trouble Shooting page and my adapter is not listed as one not supported.
I downloaded and installed the latest driver for the NVidia but LR still would not recognize it. It simply said it was not supported and in System Info that OpenGL failed. It didn't even list the NVidia adapter. The problems came in when I started following the Adobe GPU Trouble Shooting suggestions. A 'clean' install raised additional issues in that the NVidia Control Panel would not open. Through research, I found that this is a know 'feature' that I was not able to overcome.
I decided to perform a hard boot. At that point, the NVidia adapter was not detected and I was using the default low res Dell adapter. I looked in the Device Manager and found the PCI Controller device driver had not loaded because it was missing or corrupt. Additional reseach showed this could because of a registry problem. I suspected the Nvidia 'clean' install. I ended up having to uninstall the PCI Controller and reload it using scan for new devices.
At the end of the day I was able to get back to (what I hope) is a stable environment by completely uninstalling NVidia and reinstalling it. For some reason, some PCI devices had to be rediscovered and I think I have an issue with recognition of my additional monitors.
LR still does not recognized my NVidia and because I still can't open the NVidia control panel, I can't continue the troubleshooting steps.
So, this is a long description of problems with NVidia that I discovered which was frustrating and very time consuming. I have a computer background and can see that someone else could be left with an unusable systen and having to resort to a Windows recovery to an old check point to get back a stable environment.
I really wish Adobe would invest in a tool to check a system for compatibility with LR features. It could save a lot of grief. I did find the Trouble Shooting articles by Adobe useful but that only shows that Adobe knows there are problems dealing with GPU's.
Hence, with the apparent danger, if you have an older (which I suspect could be an issue) system, is it worth trying to get GPU working?
