I am currently trying to get realistic output in 3d environment walkthrough in unity mobile but due to the high usage of mobile cpu i am not able to get a lag free output. I tried the vertex lit render option but it reduces the quality. I have made a low poly object for more optimization.
Not possible on current gen mobile GPUs. In John Carmack’s words: “Old-school graphics, like a Gamecube”.
