Hello,
I've been messing around Apex Calculator and I was checking if FOV is actually calculated correctly with cl_fovScale in-game. Here is what I found. Before we start I would like to say that I've checked it on every resolution no matter what the result is the same. That error gets to HIPFIRE ONLY, but let's get started.
Recently, I found that cl_fovScale doesn't 100% correctly calculate FOV to game, ex. cl_fovScale 1.25 = 87.5 in FOV Slider, but it doesn't go to 87.5, it has to be natural number so it has to round the number to NATURAL, correctly with the math it will be 88 and then it scales to ur ACTUAL hFov. So let me show you that in that range: cl_fovScale 1.250000-1.264285 means in FOV Slider: 87.5-88.49 and that stands FOR: 88 base FOV. As I don't know how to explain it, I did video.
Tried my best, feel free to ask about that.
