Lightroom extremely slow reopening file edited in Silver Efex (Nik Software)

[Xtof36]

Issue after editing a file with Silver Efex (through Lightroom CC) : new Tiff file takes minutes to open and refresh in lightroom. Lightroom extremely slow and non responsive.  Impossible te work with such issue.

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

And what version of DxO NIK Collection. If v5.0, look for a update to 5.1

Well actually 5.4 (link below a tad old)

I;m having exactly the same problem with all my LR plugins. Seems to have started with latest LR update. TIFF files take forever to load and LR is completely unresponsive.

I have the same issue. Very frustrating.  It works on photoshop fine.
