Denoise AI 2.3.2 hangs when selecting Auto

It seems that if you select Auto before you have done a preview update, Denoise 2.3.2 doesn’t respond anymore and needs to be closed with TaskMgr.

Please go to Help-> Graphics info and press Copy then paste the info here.

Application & Version: Topaz DeNoise AI Version 2.3.2

Operating System: Windows 10 Version 2004

Graphics Hardware: GeForce GTX 1660 Ti/PCIe/SSE2

OpenGL Driver: 3.3.0 NVIDIA 456.38

CPU RAM: 32686 MB

Video RAM: 6144 MB

Preview Limit: 6651 Pixels

That all seems OK, can you go to File-> Preferences and check what is there, it should be either:


I have a similar setup as you but a GTX1050/4GB and I am not having problems with either setting. Note your NVIDIA driver is last version, current is 456.71

The other option is to press reset in the advanced preferences and let it calibrate again.

Note that with the GPU set to off it will be a little slower generating the preview but it will start with Initializing on the panel before generating the preview the first time which takes about 30 seconds , thereafter normal as it needs to load the OpenVINO libraries.

That’s it - many thanks! After installing 2.3.2 I had reset the preferences. The situation where Denoise is busy with itself and Windows stating it doesn’t respond seems to be exactly this. After coming back, everything seems to be normal.
