Why is it interesting? What controller do you use?
Edit: I've actually found that it's way easier to beat people with a controller. It could be because I've mostly played console most of my "gaming career".
Since you've tried reinstalling the only thing I can think of is your hardware. What are your computer specs?
Edit: In the past I had a terrible Windows XP. I was able to install some games and get them to run for a short time before they inevitably crash.
Hello I'm going to make this introduction short. I love to play Halo, I play many different versions (including on Xbox) so if you see someone with "Life Just Is" that'd be me. Also, I only play with controller. Yes I use controller on PC.
