Still getting input lag most of the time that randomly goes away and comes back, no idea how to fix it.
Still getting constant frametime spikes which stutters the game, this isn't frame drops and its when the CPU/GPU are well below maxing out.
Also not sure if its related to the issue but why is full screen optimisation still forced on? Even if you turn it off in .exe it stays on in game.
if you do actually mean input lag, as in feeling a delay when aiming and stuff, then use the following starting command:
Just tried this and it doesn't make a difference.
The input lag I get is pretty much there all the time but it randomly goes away and feels silky smooth and like I'm not dragging my mouse through sand but then comes back again. The game is playable but it feels like sh*t.
