Hi!
Could you open a bug report via ticket or separate forum thread on freezes? I don't think we've had any reports about the CPU denoiser doing that (btw, are you sure the NVIDIA denoiser was unchecked for "during IR"?). https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006-how-to-report-issues-3ds-max for how to report the issue.
On results, the Intel denoiser should always be significantly slower than the GPU denoiser, but faster by a little bit than the Corona Denoiser. Quality on the Intel denoiser is, like the NVIDIA denoiser, not as good as the Corona High Quality (as our denoiser uses additional data that those two alternatives do not). Because the Intel denoiser doesn't use all the data that the High Quality one does, it does use slightly less memory (not a huge amount, but some).
Its strange for myself too...cause I used CPU UI denoiser before and it worked very well on the scene that I was working on before ...but recently I can't use it ( I think it's gonna freeze on the high resolution renders ) ...and honestly I can't gives you any information or crash report cause not only my 3dsmax freeze, but also my whole system is gonna freeze ...the only option that I have when it freeze is pushing power button and shutdown the whole system....
and of course the quality of the CORONA HIGH QUALITY denoiser would be much better and I just said that CPU denoiser quality is something between corona high quality and nvidia denoiser quality....I didnt say that they're exactly the same :)
Version I used In this test was :
Corona 4 - daily build - 20/02/2019
and
Corona 4- daily build 22/02/2019
