Or it's something else?<br /><br />I did compare it to Microsoft's implementation, and indeed it seems quite faster. But to be frank, I'm more interested in vendor DXR implementations rather than Microsoft's.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-398682525365778708.post-3872568409519426452018-09-09T14:39:23.305-07:002018-09-09T14:39:23.305-07:00Yep that is a bit confusing.

On everything else it is very slow.<br />I hinted towards the fact that even if you compare DXR on RTX GPU with our handwritten implementation, it should look favorable. <br />Don't take my word, download the source code and try it ... you can also try on many platforms :-)<br /><br />Let me know how it goes.Wolfgang Engelhttps://www.blogger.com/profile/11031097395025597662noreply@blogger.comtag:blogger.com,1999:blog-398682525365778708.post-11865840409470941372018-09-07T15:43:24.740-07:002018-09-07T15:43:24.740-07:00"When using DXR, we expect Hybrid Ray Traced ..."When using DXR, we expect Hybrid Ray Traced Shadows to run on all hardware apart from the GeForce RTX with subpar performance"<br /><br />I'm a bit confused by this statement. At the moment, Nvidia RTX/Volta is the only hardware that actually supports using DXR. Are you suggesting that the other vendors are going to release DXR implementations that are sub-optimal compared to what you have in Confetti?
