bodes well i think for raytracing... and will work on all modern gpus not just limited to RTX. hopefully all game engines will get it but for now cryengine only.
but that running real time on a vega 56 looks fabulous imo...... i hope it gets support and in vr titles too.
Yea, there is still a reason why NV added those RTX cores. AMD might be able to pull off some level of RT - but the gambit of the API still would highly benefit from a hardware acceleration.
Though I think for now - GI could still be fake well enough to get around with current methods while we focus more on trying to get reflections and physically base shadows working first. Granted - that is harder done without GI. Refraction can be put on hold for a while - but I could think of a few cool ideas game design wise for it - if it was design around using that instead.
