Ask Slashdot: Low-Latency PS2/USB Gaming Keyboards? 177

An anonymous reader writes "I've a cheap but low latency mouse (A4Tech) and I noticed my trusty old wired Logitech PS/2 keyboard seems at least 50ms slower (if not more) than the mouse when I test with those reaction time sites. I even increased finger travel distance over my mouse button to make it fairer and the difference still remains. So either the tests are slower with keyboards or my keyboard is high latency. Assuming the latter any suggestions for a good reasonably priced gaming keyboard? Extra function keys might be nice but since my hands aren't big what would be better is being able to output a custom key/combo if you hold down (special?) keys while pressing another key. For example I could configure it so if I hold down "Special Key 1" with pinkie or thumb and press 4 it actually outputs 9, and if I hold down shift as well it outputs shift+9 (and not just 9). Being able to replace the capslock key function and have it behave as another key (or a special modifier) would be a bonus — I've never needed capslock and have probably used it more by mistake than for its normal function, or to test how badly a PC has hung."

    I did some testing in that regard and the most important thing which can completely ruin gaming experience is latency caused by cable length. I would recommend to cut the the length to two feet maximum, replacement by the oxygen-free copper cables is highly desired as it is well known that cheap cables slow down the transport speed of the electrons (any professional audiophile will confirm that). If you are using wireless keyboard, please close all windows as any airflow/drags can cause variations in the response times.
