good nuff to run all 2013 games on high settings
I'm giving you the benefit of the doubt, so specify the specs.
We aren't mindreaders who just happen to know what you have. I was able to run all games on high with 2Gb RAM and lousy intel dual-core, does not mean the game runs smoothly.
Helping you with the problem is next to impossible with the information you've given.
Let's do the questions again and see the answers.
Is the game pirated version or not?
Does running the game's .exe create a process for it in Task Manager's process tab or just do nothing?
What fixes have you tried?
As for Crysis adding the license files back, that's nothing new. The point of deleting them and restarting PC is to get fresh files incase of possible corruption or shit like that.
