When attempting to melee enemies or when I and an enemy turn the same corner into each other it is not uncommon to completely lose target and get completely disoriented with where the enemy is because we physically go through each other. Meaning I lose focus and have to desperately search for where he went and usually die trying.
However, this is also causing me actual pain because I have sensitivity to changing focus that quickly. It’s hard to describe, but it is really hard for me to go from really focused to disoriented. It causes extremely bad headaches to go from very focused to completely lost when an enemy disappears from off my screen in what appears to be instant.
