Whoops V yes, I was meant to say healing is Y and grapple/melee is V, either way they are odd keys to set both actions to I find.Your grapple was on Y? Mines been on V since the beginning and I havent changed it?
You mention mouse response was excellent , what FG did you have it on out of curiosity, you mention you had it on but not whether it was x2,x3 or x4
FG was at 2x when I did use it, it felt fine but you could 100% tell there was some latency, but it was low enough that it's the kind that you'd quickly get used to. I just left FG off after testing it as the game is super snappy with it off even when in the 60+ fps range.
