There's a widely-reported problem of Crysis not being able to start up. I still have the same OS (Windows 10) and hardware from when I last played it on GOG, so I think it was broken by either a Windows 10 and/or a GeForce driver updates. I found a very simple fix to get it working for me, which does not involve downloading anything: 1) In GOG, go to the Crysis main page 2) Settings > Manage installation > Configure > Features 3) Scroll to the bottom and click "Add another executable / arguments" 4) For File, select your Crysis launcher file. On my machine, this is: C:\Program Files (x86)\GOG Galaxy\Games\Crysis\CrysisLauncher.exe 5) For arguments, enter "-dx9" (without the quotes) 6) Select "Default executable", then click OK 7) Click Play, the game started running normally for me
