We have plenty of real uses for ray tracing right now, from blender to whatever that avatar game was doing to lumen to partial rt to full path tracing, you just can’t do real time GI with any semblance of fine detail without RT from what I’ve seen (although the lumen sdf mode gets pretty close)
although the rt cores themselves are more debatably useful, they still give a decent performance boost most of the time over “software” rt
