S.T.A.L.K.E.R. Multiplayer Patch



This official patch replaces the defunct GameSpy multiplayer service with GSC Game World's own service.

This patch can be applied to the retail versions of the following (Steam versions already have this patch applied and GOG.com has its own installer):

  • S.T.A.L.K.E.R.: Shadow of Chernobyl version 1.0006
  • S.T.A.L.K.E.R.: Clear Sky version 1.5.10
  • S.T.A.L.K.E.R.: Call of Pripyat version 1.602


STEAM users will get the patch automatically.

This patch can be applied only to the latest version of each S.T.A.L.K.E.R. game:

Shadow of Chernobyl - 1.0006
Clear Sky - 1.5.10 (1.0010)
Call of Pripyat - 1.6.02


1. Switching multiplayer game to GSC server
Because of the declared closure of GameSpy multiplayer game services, we made our own server intended to replace GameSpy
This update is required for S.T.A.L.K.E.R. game clients (and servers) to enable establishing connection to a new server.
All CD-Keys issued before are still valid on a new server.
New players' profiles should be created in "Call of Pripyat". Game statistics is not maintained.

2. Enforcing vertical synchronization for rendering engines
Patch can enforce vertical synchronization in a render loop to prevent negative artifacts on high-end graphic cards caused by very high FPS.
