I hear people saying that but if you increase your monitor gamma all the grey colors go up linearly, and not increase exponentially as the amount of 'lightness' increases.

For example if I have 3 colors of grey,

dark grey (brightness of value 2), middle grey(brightness of value 8), light grey(brightness of value 14)

If I were to increase gamma with my monitor It would just become:

dark grey (brightness of value 4), middle grey(brightness of value 10), light grey(brightness of value 16)

The color difference of the greyscale would not change, just become lighter, thus not make it easier to see. (Every color would get 2 increased brightness)

The games gamma slider is prerender, it increases contrast by exponentially increasing gamma the higher a base brighness becomes, for example:

dark grey (brightness of value 2), middle grey(brightness of value 8), light grey(brightness of value 14)

becomes:

dark grey (brightness of value 4), middle grey(brightness of value 16), light grey(brightness of value 28)

In this example all the brightness values get doubled instead of increasing the value by 2 linearly.

Obviously I have no idea what the actual numbers are, and most likely it's not a perfectly exponential increase like ^2. But I hope the idea is a bit more clear.

The only solution I could think of is to change the gamma slider from an exponential one to a linear one, like described with the examples. That way people can still change the gamma, if they have a very light or very dark monitor, and still have no benefit whatsoever. The thing they have to do next to this though, is make sure that people cant use a prerendering contrast adjustment like sweetfx, using battleeye.
