To conclude this topic:
I've been now using R23, I've made the switch during two projects, but I am finding R23 a bit more stable than S24.
There are some unfixed bugs of course that this version will die with.. but at least, performance wise, I can work better and non stop, compared to some weird freezes and sudden closing of application I was getting at S24.
These issues have been pointed out to be a nvidia driver issue, since I am using an older version of the driver, because the new one, freezes with Redshift completely, not just C4D and Redshift, but the whole computer, for a few seconds.
After I am done with the projects, I will give R25 a try (I will cry about leaving Signal behind of course... 😞 hehe))
Thank you all for your inputs!
