Really? Because your post flat out states that I am just not "good" enough to recognize that I might have a hardware problem - but you are. It spells out word for word that I don't know what I'm talking about and that does irk me a bit.
I'm not saying that keyboard ghosting is not a real issue for some combinations of keyboards, people and games. My original point was and still is two things:
1. It is almost impossible to find a modern keyboard that generates ghosting issues in even the most extreme game play scenarios.
2. Because of how keyboards are designed, trying to type with both shift buttons held down is a meaningless test that is more designed to "break" keyboards than to actually test their capabilities.
If anyone wants to ACTUALLY test their keyboard for these issues then you should visit this page and try any key combination you can imagine you would use:
If you believe either of my points are invalid, it would need a better argument than "maybe you're just not serious enough in your gaming".
