Try this config in order to get better FPS! Aimed to those with low-end graphics cards to mid-end!
You might ask: How do I execute it?
First, go to the directory where you have Steam installed and access to your Counter-Strike Source Folder and then your config folder:
Copy the file attached here to that folder.
Then Right Click the file named "config.cfg" and Open it with Wordpad.
Copy this into the last lines of the file:
echo "CSS FPS Config Executed!"
echo "overclock.net ~ The Pursuit of Performance!"
Save it and then run your Counter-Strike Source!
Now open up your Console by pressing the "~" key on your keyboard. If it doesn't work go to Options > Keyboard > Advanced > Enable Developer Console.
Then once the console is opened, type in "net_graph 3" and you will see your FPS.
