lol that show was for GIRLS
... Okay, well when someone gets off their butt, this should be locked.Does this mean I got the job?
125 keys per second.Amount of keys a human can press in 1 second = ~50
PS/2 works 1454.55 keys per second.
your 60Hz Monitor running your 658FPS game is only displaying 60 FPS to you.
"Default Windows USB polling rate = 125Hz"
And if you have a high grade product it doesn't follow default windows rates!
My mouse runs at a 500Hz Polling Rate.
Lets remember Higher Number does not mean better. Higher rates require more processing power from the mouse, something no PS/2 mouse is going to hit at anyways. Running above 125Hz on any PS/2 Mouse will result in massive lag on your mouse.Quote"USB is much faster, but the bandwidth is across many ports as opposed to one port."
"Despite all of this theory, USB is more or less on equal footing in the real-world, even though PS/2 is faster (more direct) and offers NKRO capability. After all, you're probably not printing documents and gaming at the same time. Really, the only hardware combination we'd be worried about would be a fast storage device connected to the same USB root port, since bus utilization of up to 100% is possible in that situation. If you really needed to, you could always disconnect high-bandwidth USB devices when they aren't being used.
The often-recommended trick of turning off USB webcams and microphones won't help. Isochronous transfers always have an open window of at least 20%. So much for the myth of data rates and input lag. Delays will always occur, whether you want them to or not. First, there's the fact that keyboards have a built-in delay. And from there, it's up to the keyboard itself. Which combinations of keys in which quantities can be struck simultaneously?"
Honestly when it comes down to it. All PS/2 is good for is pressing more then 6 keys. Something I doubt you do much anyways.
GOOD DAY TO YOU SIR!
Since you guys wanna be a bunch of asshats. Heres math for you.
USB default Windows polling rate is 125Hz, i.e. it has 8ms latency or lag between each packet. Now, even though each packet is 8 bytes long it seems USB keyboards still need to communicate only one key per packet, and that comes down to 125 keys per second.
PS/2 works at 10-16 kHz and I think protocol defines 11 bits per packet. That comes down to 16,000 / 11 = 1454.55 keys per second.
To provide an example of what these numbers are crunching, its basically how many keys you can jam into a frame. So lets take a fighting game for example. The difference between the two keyboards is how quickly I can execute the keystrokes to do my combo. For the USB I can execute two key strokes within a frame, while using the PS/2 I can obviously jam around 22 keys per frame, which, if you've ever seen any good fighting game players, is the difference between winning and losing. A lot of moves have start up frames of invincibility in modern games so that key difference between frames can be pretty drastic for some gamers.
Now, if you want to actually contribute to the thread, that'd be awesome, or if you just want to be a bunch of cancer to CG, keep on trucking like you guys do.
