FOV Type, how to keep consistent true FOV between games

[Shyver]

I'm having some problems with fov type, 

the game I want to use for conversion don't have the same types of FOV, is there something to be done ?

I want to convert from Apex Legends to Team Fortress 2 and TF2 don't have the option for multiplicative FOV

You can't convert the multiplier between games, it is unique to that specific game. You need to use a standard FOV Type, the easiest is Vdeg. So select Vdeg for TF2 and copy the "Actual VFOV" value from the Apex calculations.

The FOV you need to configure in TF2 will then show up in the "Config FOV" in the output.

Thank you very much for the answer to this problem !

I'd like to understand a bit more how all of this works.

TF2 for example comes with the preset of Hdeg 4:3, why is that and why changing it to Vdeg works ?
Also this would suggest that the FOV type in Apex doesn't matter ? Since we're using "Actual VFOV". Would changing the FOV type of Apex to Hdeg 4:3 like it is on the TF2 preset work ?

Basically, why is it that Vdeg works as Actual FOV in this situation and could it work for any situation, then why are there other options if it does ?

Hdeg 4:3 is the FOV type the game uses, the calculator will always default to the correct FOV type for the game you select. When you switch to Vdeg, you simply tell the calculator that you want for instance 72 vertical degrees. It will then calculate what you actually need to configure in the game to get exactly this.

Absolutely, the output will then tell you what multiplier you need to use to get the Hdeg 4:3 FOV you want.

Any of the FOV types work for this, but the output doesn't tell you all of them. It only shows you the true vdeg and hdeg, so it's easiest to use one of them. Vdeg is also the most commonly used type. If you already know your preferred FOV, let's say 90 Hdeg 4:3, you can perfectly fine use this for all games that supports changing FOV.

Thank you very much for the explanation !
