A couple models were missing in my last game. Most time, both supports looked like blue spirit-orbs. Enemy Cassidy was completely invisible to me, as well as my own Cassidy had no model.
I don’t know if it happened mid-game or from the start on. Maybe they switched characters when I noticed the bug.
Two games before, I had some weird sound bug. Only half the sounds were normal, the rest sounded like it came through in game voice, but no one was talking.
Happens to me too.
I assume it is because of game trying to constantly load models/icons from HDD/SSD without having a proper fallback versions nor caching them in the memory (profile icon in the bottom left corner will load every time player dies).
It happens because some of HDD/SSD can just start giving errors on way too frequent attempts to read from them, mine does exactly that, especially when it overheats. It did kind of fixed the issue when I fixed cooling on my laptop but it still happens.
I often have to complete games without seeing or hearing anything. Hero like Roadhog also causes memory leaks overtime when that happens. Models usually disappear completely once players start switching them.
I don’t remember if that was the case, but I think it makes Moira and Sombra visible too.
Shooting as Cassidy feels more fun as it removes camera recoil animation which was a part of his hands animation that failed to load.
It also happens on some hand held devices that don’t have powerful enough HDD/SSD.
