Basic instructions:

1. Once you have unziped place anywhere you want.
2. Delete any autoexec.cfg files found in the Crysis 2 root folder. (if you're asking what that is, don't worry about it)
3. Delete any target commands you may have put on the shortcut as they will override the autoexec.cfg that is created
4. Run the Crysis2AdvancedGraphicsOptions.exe
5. Hit apply once all settings are set
6. If it's not working right, try running the program in administrator mode
Als Administrator ausführen, vllt klappt's dann. Hab 3 Versionen (1.5, 1.6, 1.7), alle laufen einwandfrei, kann dir also keinen weiteren Rat geben.
