My PC has dust on it and I use it 8 hours a day so I would skip the dusting and go straight to editing .ini/.dll files to remove the chromatic aberration effect and extend the shadow capsule distance by 4m, but the ini edit didn't work because you edited the masters and not the user versions so you feel like you're going nuts because it doesn't look any different like the guy on the forum said it would.
Then you install a game-ready driver and it breaks another game you're playing from 2009 and you get annoyed turn off the PC and boot up your console.
