VR technology is the one of the most high class technology, and the mentioned information is really very interesting, But when I try to open it to my Hp Support Assistant computer I didn’t do anything can anyone suggest me any technique to doing this thing.
Innovation fostering excellence in education and VR is one of the most changing innovation. But when i start using it with my tablet, HP Support Assistant utility blocking it.
This is Latency? if yes pimax announce 15ms?and we have 16-17ms? if yes i think it’s a honorable result… ty for the post.
