As far as I'm aware, going from a native 16:9 res (e.g. 1920x1080) to a lower 16:9 res stretched to aspect ratio (e.g. 1280x720) should result in the same exact movements in CS:GO relative to monitor distance and 360 distance, as there is no change in FOV and everything is the same (IRL) size relative to the other 16:9 resolution due to stretching.
However, if you switch from a native 16:9 res (e.g. 1920x1080) to a lower 4:3 res stretched to aspect ratio, I'm not certain if it would have the same outcome.
The 4:3 resolution, since it is stretched to aspect ratio, would fit the screen vertically but have black bars on the sides. The 360 distance would still be the same since CS:GO's sensitivity is not affected by resolution.
I'm thinking that the monitor distance would be exactly the same since the ingame FOV doesn't actually change; part of it just isn't rendered at all, therefore each count of mouse movement should still accurately correspond to the amount of degrees that it would correspond to on 16:9.
Basically the horizontal black bars would have the same effect as sliding pieces of paper over the screen - they don't actually change the monitor distance/360 distance/engine fov - they just make block part of the screen from your sight.
Am I correct in thinking this? I apologize if the question has been asked before, I didn't find anything about it while searching.
