poor laptop = poor performance. Can I change that?

Just like the title says. I play on the HP Probook 4530s laptop, which is not enough to play games at even 30 fps, and definetly not stable 30 fps. On DBD the most the game can handle is like 15-16 fps, but obviously the longer I play the less fps I have. What I would like to do is try to tweak fps in some of the game files. But I've been seeing mixed answers about whether you get banned for it or not. Obviously I wouldn't want to get banned for it, but I do want to try this to get even 5 fps more. So the question is simple: Will I get banned for tweaking fps in the game files?


basic basic info about my laptop:

- 4 GB RAM

- Intel core i5-2410M 2,3 GHz

- Intel HD Graphics Card 3000 and also AMD Radeon HD 7400M Series one (1GB)
