One of the worst-kept secrets in gaming is that PC players often have an unfair advantage over players on other platforms, when playing online multiplayer titles.
However it wasn't until recently, when cross-platform play became more prevalent, that this started to come to light more often. In particular, more and more internet personalities and streamers are starting to voice their opinions regarding the issue.
A more recent example of this is YouTuber Jack Mason, otherwise known as JackFrags. JackFrags Makes Suggestions on How to Level Playing Field https://youtu.be/uMBEvgiKqBs You'd expect that a comparison between PC and consoles in Call of Duty: Warzone would revolve around the existing cheats in the game, but you'd be wrong.
In his recent video, shown above, JackFrags explains that cross-play causes two issues that give players on the PC an unfair advantage. He then turns his attention towards, not exploits, but rather, the filters and FOV slider.
With the first issue, JackFrags talks about how PC players are free to change up the visuals of the game using NVIDIA Filters. He cites a scenario where a PC player can make certain darker corners of Verdansk look brighter all with the press of a button. This supposedly then allows that player to see other players hiding in the dark or under staircases.
This shouldn't be the case. These ambush spots are an important part of Call of Duty: Warzone. PC players shouldn't be able to spot well-hidden players with ease. As a result, JackFrags is pushing for the developers to fix this. He suggests that they find a way to remove the ability to use filters in Call of Duty: Warzone in the name of fairness.
