Render cache and third party OFX Plugins

hello,

New to Resolve and this forum so please be gentle with me if this has been asked and answered before!

I have installed some third party OFX plugins into Resolve 17 (Boris FX - Sapphire) and I'm having problems when turning on "render to cache" to help with playback.

Caching seems to work correctly when using Resolves own OFX plugins but when I try and use any of the third party ones the line stays red or sometimes it turns to blue but the playback is still around 4-5fps.

Is this is a bug or am I doing something wrong? any help would be much appreciated.

thanks.

I'm having the same problems: played and thus rendered clips won't be read from the cache next time I play the clip but will be re-rendered every time - again at ohne 5.5 fps.
Help is very much welcomed.

Caching on the edit page for third party OFX does not work as it should, try to add the effects in the color page instead
