Do NOT play on Steam. 50% FPS Potential!
TL;DR: Battlenet and Xbox App have 100% or more in FPS. Same setup and settings me and multiple other get 120FPS on Steam, and 250 FPS on Xbox app and battlenet. I have only tried Xbox app vs steam, since I do not wanna download on battlenet too. (This is on the latest update with omnimovement)
EDIT 2 TL;DR: This doesn't work for everyone, For me it doubled fps, for some it seems to give no change. Not sure what is the parameters to know if it will work for you though. If feel you have low fps for ur system, try it!
I didn't believe this at first but just letting everyone know. I tried playing the new Warzone with the Omnimovement update on steam. I got around 120fps with A 4070S And 7800X3D. I also played the Mutiplayer through Xbox app and got around 200-240 there.
I felt 120 fps was super low, and it even felt WAAY less than 120, it was supper stuttery. So I found videos showing steam vs xbox & battlenet. You get 50% FPS on Steam in the latest warzone update.
Here are the videos I found:

They are all correct, I verified myself now. I got 250FPS on Xbox App Warzone, and on Steam I got 120fps but it felt even worse than 120. So I recommend changing to battlenet since xbox app download speeds are so bad. I am not sure if this is only warzone or bo6 itself since I only have tried multiplayer on the xbox app.
EDIT: As BonusEquivalent6895 said in a comment, you are able to transfer ur progress from steam to for example battlenet via logging into the same activision account that you were using on steam on the battlenet download.
EDIT 2: This isn't gonna work 100% of the time, I do not have any information on what is causing it, but for my friend it seems to have basically done nothing, I also saw someone else say that it did nothing for them. So beware that this is not 100% success rate. But if you feel your FPS is extremely low for ur system which I did, it is definently worth trying.
