Many devs are worried about the possible implications this may bring for competitive gaming between clans etc.
One idea we are thinking about however, but no guarantees we will implement it, is an "Ultra Low GFX" option that will put all the settings on low, but on top of this force the player to play at a View Distance setting at 50% or 75% or so of that of the level. This way any advantage they may have from running on the low settings, they will loose from players potentially "shooting out of the mist" at them, as well as significantly increasing their FPS at the same time. Anyone who doesn't want to play with this serious disadvantage of the lack of VD, while also playing with the other slight advantages Low GFX brings, can always choose to run on current medium-low settings or above without this disadvantage.
But right now that I must stress is only an idea that's floating around, our key guy for implementing it is currently really busy with r/l stuff and not sure if its really possible, or if he will have time in the future to do it etc but we will have to see
As for your video, are you sure that's v1.0? Also any idea what map it is, what part of the map etc and what settings the player was playing on?
At the end of the day however there are going to be differences between different gfx settings and we can't hope to have them all fair unless everyone is forced to play at the same level, which isn't going to happen but we are looking at minimising the advantages and disadvantages there may be between them.
