You may believe that, but it is impossible.
 
On an Amiga you can change the display in realtime, so you could change one of the palette colours or play a sound and then read the joystick on every scan line and instantly change another palette colour or play another sound.
 
With usb the default polling rate is 125hz, you can increase it but I'm not aware that winuae reads the state more often than every screen refresh anyway.
 
It is very difficult to keep the sound and video synchronised because of latency in the drivers and lcd monitor. You only present an entire frame of video or audio at a time, so there will always be some form of latency.
 
You might not notice, but it is there. Some people perceive it stronger than others.


True. Outperform is one thing, but lag and performance are different concepts, often mixed up by people. You can have a program running 50x times faster and even then it can be several frames behind. In fact, less than one frame delay is enough to modify how a game control feels. I can only stand the real thing and FPGA implementations, wich have zero added delay.

I'm using FPGA on a CRT monitor (not a 1084 as mine died years ago, but the Minimig supports 15Hz modes and I have an SCART cable for it so I can connect it to CRT tv). The Minimig includes optional scanlines, so I don't think I could tell it from a 1084 image.
