50 ms is too high
at 256 sample rate should be 6.30ms at input latency and 30.27ms at output latency
please check your usb bandwidth ,it should be used 73%
i did a fresh install but it still had the same problem. just changing patches when i start and stop my track.
this time my latency is 0 with input and the same as output. i have selected the usb asio driver from the virus ti
