hi,cal: In my opinion,FPGA card seems to have little connection with Latency thing. Generally speaking The PC system just give the FPGA card a command,so how to send pulse (or voltage),and read encoder number is the duty of FPGA itself.I think that will take little resource of PC.The Latency is sth about the character of OS,(also too much work load may also affect but obviously FPGA board NOT)
