I’m just saying I’m certain games setting your custom resolution could be considered cheating.

For example in competitive first person shooters, if you play on a 16:9 monitor, and you set the resolution to be a ratio much, much wider than your monitor, you will see all the way around the player in 360°. This is how graphics projection math works. Or it did wheni last dabbled in writing a graphics engine.

So I can understand some games not allowing certain odd ratios and FOVs in combination.

Otherwise I agree, of course we should be able to set a resolution that matches our monitors that we have. 😊👍
