A lot of PC players play low settings because they have average/mediocre PCs. If you look at Steams hardware charts, you’ll see that. Also, isn’t it fairly normal to play FPS PvP on low settings? e.g. CS GO, Apex, CoD, etc…
I think this is a “don’t hate the player. Hate the game…” scenario.
I play PC, fairly high settings (because I can, and don’t really care about winning/losing), but I’ll change to lowest and see what a huge difference it makes. I’m sure it’s night and day…
