The affinity.zip file you have requested: Tools and Utilities / Affinity Fix Quad Core (0.1) - 51.66kb is not available. Perhaps try browsing all files for the game S.T.A.L.K.E.R.: Clear Sky and upload any files you want to share or are missing. This is the only information we could locate:
Insert File into the Clear Sky Directory and execute. It should launch Stalker - Clear Sky then wait 30 seconds and set the affinity on the xrEngine.exe process to use four cores instead of just one.This helped make the game run smoother for me, This file executes STALKER - Clear Sky, waits for 30 seconds and then sets the affinity to all four cores.
