Speed cheat fix coming "real soon now"

The latest news on the ‘speed cheat’ thang doing the rounds on all Counter-Strike and Half-life servers comes from Yahn Bernier (Valve’s lead programmer) sent to the HL Developers list:

The way it works is that your computer reports more ticks (GetTickCount, timeGetTime, and QueryPerformanceCounter are all affected ) have passed than have actually passed. Programs don't run any faster, but time on your PC runs faster. This is a problem in most games, including HL, because we need to know your framerate to determine how to sample your input/movement commands. Determining your framerate requires us to read the clock using some method ( such as the above functions ). The server and client then run the simulation ( the server is authoritative but the client runs it for prediction purposes ). The solution is for the server to make sure the client isn't trying to simulate for more time than has actually passed on the server ( with a small margin of error ).

We're testing that fix and it seems to work; it should go live "real soon now".

Good 'ol Valve
