I have noticed there is a texture update latency in Unreal. In my rtsp media streaming decoder plugin from live camera feed I get about 220ms latency in Unreal where in my example opengl render i get about 120ms latency in texture update.
Is there a way to tweak the texture update rate in Unreal Engine?
The attached image shows my latency test. Hardware used: Asus Monitor 120Hz, Canon Rebel T3i camera, GoPro4 camera, Teradek Cube 205 video encoder.
Actual time is 1:45:65
My OpenGL renderer shows 1:45:53 = 120ms latency
Unreal shows 1:45:43 = 220ms latency
I did multiple takes and unreal is constantly 100ms slower then my OpenGL renderer
