Hmm, interesting stuff this
PowerVR Ray Tracing. Original page is gone so had to go for a google cache. Company has since been bought by a firm called Canyon Bridge but who they have ties to in the industry is difficult to find out. I just find it curious that Jensen said touring and all those rtx features have been 10 years in the making yet this company is able to do the same basic stuff on a cheap not worth mentioning GPU and before nvidia, well we of course don't know if nvidia has been sitting on their rtx tech for the last 5 years not wanting to show it off, but i doubt it. I think there is a youtube demo of this also floating around somewhere.
