Just informational for anyone curious. I just did a count of rtx cards on Steam Graphics cards survey. Rtx cards currently account for just over ten percent of users at 11.33%. Rtx cards currently have a growth rate, at least on Steam, of less than one percent per month.
Obviously the growth rate of Rtx cards will increase over time but it’s very slow at the moment. That’s not even to mention that decent looking bounced lighting, and other raytrace stuff, on a medium complex scene still doesn’t give enough framerate, in my opinion, on first gen rtx cards.
Enlighten, even having to twist its arm, tweak settings, and wait on precomputations/baking, was still better than nothing. It looks pretty good and gives better framerate than almost anything else out there for realtime gi. I know some of us in here want a drop in solution and Enlighten wasn’t quite that, but without Enlighten we have limited options. Mostly voxel tracers.
Soo more information dump of other options, some likely already mentioned in this thread. I’ll put NeoShaman first because he/she regulars this thread
Realtime global illumination options:
RTGI by neoshaman (not publicly available?)
SEGI by Sonicether, lots of voxel tracers based off this (tested working in Unity 2020 standard pipeline)
https://github.com/sonicether/SEGI
Nigiri almost-dynamic voxel-based by ninlilizi, this girl cracks me up, known for hijacking other global illumination threads. She’s got a newer version in the works that I’m highly curious about.
(old version but tested working in Unity 2020 standard pipeline)

SRP-VXGI by Looooong (tested working in Unity 2020 standard pipeline)
HXGI by Lexie (not publicly available), really curious about this one as well.
SSGI (ScreenSpace Global Illumination) by Raul_MadGoat (will be paid - not publicly available yet)
UPGEN by mm_ASH (Paid - Downloadable hdrp demo on store page, standard pipeline also available)
REAL-TIME Ray Tracing by Parsafari (not much info, no rtx card needed?)
edit - dang darn Unity forums forcing youtube embed!
Unity RTX raytracing just to list it (tested working on Unity 2020 hdrp)
