Question

GPU degrades performance in LC

Hi

 

I observe that the Developer module becomes sluggish when enabling "Use GPU for image processing". It looks like both the CPU and the GPU is running at a relative high load even when I'm doing nothing in the GUI. The responce gets very slow when using masks, especially the brush mask. The performance gets much better when disabling the GPU. The graphics card is a bit old. Is that the problem? In case what is a recommended graphic card that will give a boost in performance?

 

Windows 10

32 GB RAM

Processor: AMD Ryzen 7 3700X 8 Core

GPU: NVIDIA GeForce GTX 960 with 2 GB dedicated GPU memory.

 

Regards

Ommund Øgård

The GPU you use is rather old and also 2 GB memory is rather low. Depending on the CPU and the screen resolution you use, you are much better off deactivating the GPU.
