Slow GPU Rendering when in Develop mode

I am a forum newbie running Lightroom Classic 7.3 under Windows 10 (Intel 3770K, 32gb RAM, Asus 660ti 2 GB GPU).

Graphics Processor Info:
OpenGL: GeForce GTX 660 Ti/PCIe/SSE2

Check OpenGL support: Passed
Vendor: NVIDIA Corporation
Version: 3.3.0 NVIDIA 391.35
Renderer: GeForce GTX 660 Ti/PCIe/SSE2
LanguageVersion: 3.30 NVIDIA via Cg compiler
Total Video Memory: 2048 MB    

With GPU enabled in Preferences, when I click on a photo (JPEG) in Develop mode the GPU rendering 'spinner' appears and slider changes take ages to render. With GPU optimisation switched off, rendering is much faster. This has only started happening in the last release. Has something changed under the covers (or is my GPU no longer 'good enough'). It is very annoying to have invested in a half decent graphics card only to find it no longer works in harmony with the latest Lightroom version. 

Any help or suggestions much appreciated.

      Your GPU (GeForce GTX 660) is not (and has never been) supported for GPU acceleration in Lightroom, and so you need to turn off the GPU acceleration by unchecking the "Use Graphics Processor" box in preferences.

      What are you doing that is slow? Be specific.

      What software are you using? Be specific, provide the version NUMBER.

      dj_paige,

      Thank you for your quick, and helpful response.

      I am a bit confused as the 600ti meets Lightroom requirements in respect of Direct X, Open GL and VRAM support. However, I'm about to pull the card and replace it with a GT1050ti with 4GB of VRAM. Hopefully this should address the GPU rendering 'spinner' problem,

      I wouldn't bank on that ReyFSmits,I found this thread whilst looking for info as to why Lightroom is quicker with GPU acceleration switched off, I am running a 1050ti 4gb card. Working through 1000+ images, all very similar and just requiring cropping, each image takes a few seconds to load before I can use the crop tool with GPU acceleration on, immediate load and crop with it off. I guess the list of supported GPU's is short! A pointless feature.
