Hi @Corvus, I'm using callback method. According to @Daniel_Y I enabled v2 and then used sample UI code to show FPS from http://wiki.unity3d.com/index.php?title=FramesPerSecond&_ga=2.258332745.253243703.1593390743-1664584608.1593097261&fbclid=IwAR2zAe7hOiiEzb822jA5lIFOlpDGXqUhf-W2WYlbf00-B4uo-Y1-IhDqYtQ
I get 30 to 45 FPS. I checked my monitor frame rate is 60Hz. Please take a look at screenshot and let me know how can I get 120 FPS.
Thanks in advance!
