If someone could manage to code such a small utility it would be quite awesome. Of course, the same rom and the same location in the game would have to be used each time. It would also record the exact time in which a display change occur (for example Mario jumping or Link ducking)ДЄnd then compare the time at which the two event occured. The external program/module/dll would record the exact time which an input is pressed. I just got an idea to measure input lag, but it would require an external program/module in conjunction with the emu.

It would be great if the entire PC system (CPU, video, audio, and HID) could be forced into lockstep synchronization so as to match up exactly with a NES, but is that even possible with common PC hardware? Much of the problem is out of the realm of the emulator, i.e., hardware and OS limitations may prevent perfect timing accuracy. But I'd say that the issue of latency in input, video, and audio is going to be the most difficult thing to perfect with regards to emulation accuracy. I don't want to discourage anybody, as there are many people here smarter and more creative than me.

and you will end up with a very large range of possible end-to-end latency.ДЄ real NES, of course, has none of these issues. Roll in the factor of process scheduling, which again, is not hard real-time, and also factor in the synchronization between the display device and the current state of the emulator (say the current logical NES cycle it is executing). Then there is the latency of your OS getting that data to the emulator.

So that is the minimum latency from you pressing a button on a controller to your OS's device driver reading the data. USB alone has a latency due to the polling rate of HID devices, which is typically 8ms. Many aspects of a computer can affect the latency measured.

So any tests would just show that for that system, such and such latency was observed.

Hence there is certainly going to be latency, and there is no bound on that latency. Windows, Linux, and OSX are not hard real-time operating systems.

Plus you'd have to control for different hardware setups, and basically the same subjective human bia would be present. People would just adjust their timing until they get it 'right' and that would destroy the whole test. For example, you do the test with Vsync on and then you do the same test with vsync off.Д«ut if you just do it with nothing to compare to, it would not be very useful. The test rom is not a bad idea, but for it to be of any use,I think it would need a 'control' environment. The actual 'test' consisted of simply pressing down and notice how responsive 'Link' was to duck.ДЄaaaaanyway.I tested this more then twenty times, and guessed right 100% of the time.So I'm convinced this is not a sort of 'auto-sugestive placebo idea' mumbo jumbo thing.ДЄgain, to anyone saying they don't notice a lag: This lag is no more than a frame (1/60) or two max.That's a lot of words for: 'I think that test was pretty objective' but an extermal mean would be even better of course. And I tested this in parts of a game (Zelda 2) without scrolling, so there wasn't any screen tearing when Vsync was off (that would have been of course a dead giveaway) I even alternated my click 'rhythm' so that I wouldn't always do an even or odd numbers of 'clicks'. I got into the timing configuration screen where Vsync is and - without looking at the screen of course, repeatedly clicked the mouse on the Vsync option and then exit, in such a way that I didn't know if Vsync was on or off when I did exited. Btw Blackmyst, I did a self-administered blind test
