No Image Quality Option in Modern warfare 3? DIY Solution for Sharper graphics

I had just re-installed Call of Duty : Modern Warfare 3 on my PC a few days back, after finishing Modern warfare 2 ( Playing modern warfare series all over again )
As I was playing the game I noticed that the graphics are looking pretty blurred and I had set all the video setting to max values.
According to an article at Gamefront, there was a solution.

"Set the Image Quality to Native"

But there wasn't any option like that in the game anywhere. 

After messing around in the game folder I found a solution. Follow these steps if you're facing the same problem.

1. Open the Game folder (F:\CoD_mw3 in my case) and navigate to 'players2' folder.  

2. Open 'config.cfg' file in Notepad/Notepad++ 

3. Find seta r_imageQuality "1" and replace 1 with 0 as shown in image above. Save the file and play the game. let me know if this worked for you.

I know this blog doesn't look so good because I am just experimenting right now with blogging and stuff. I am looking for some positive feedback so that I could comeback with a decent blog with some solutions to such problems that are nowhere to be found on the internet. Thanks :)
