Re: [hlds_linux] ex_interp
Thanks for this thorough explanation. So what's the conclusion? Can I safely ignore players that talk about modifying the ex_interp command since its value is now hardcoded or at least not modifiable by players anymore? Is this type of advantage obsolete?

No, that's controlled by cl_cmdrate Interpolation affects only the position at which models are rendered on the client's screen. The client tries to smooth the movement of other players' models by inventing intermediate positions on the screen for which it never actually received an update from the server. With ex_interp set to 0 (which you can't do any more) you would only ever see the actual position of the model according to the most recent update received. The frequency of updates is controlled by cl_updaterate. With a low value like the default of 30, the client requests 30 updates per second from the server. Without interpolation, other players' models would appear to move on the screen at roughly 30 frames per second. If your client is running at 100 fps, this will make them appear jerky, or as if they are teleporting. With interpolation, you would still only receive 30 updates per second but your client can guess (interpolate) the other 70 intermediate positions for the models, so that they can be rendered smoothly at 100 fps. However in order to do this, the client has to delay rendering the models by a certain amount of time. This is what ex_interp sets. At 0.1, your view of the game is delayed by 100ms, so that your client can collect 100ms worth of updates and then interpolate the intermediate frames before rendering them. If I recall correctly, the problem in older versions of HLDS was that the server didn't know (or ignored) the value of ex_interp set on the client, so it always expected it to be 0.1. The server then used that value to work out whether your shots hit. So when you shot a gun, effectively the server would look back in time (100ms + your ping) and see whether the player you shot at was there at that time (this is called lag compensation [grossly simplified]). Some players found that by reducing the value of ex_interp, they were able to see models in more "up to date" positions on their screen, while still shooting at the delayed lag-compensated positions. This means that you could shoot *behind* a moving target and hit it - which means with a gun like the AWP, you've just given yourself an extra ~100ms of reaction time.
