[reshade] add support for scrgb framebuffer

[startuga]

The shader works well when the game is in hdr10 but not in scrgb

Hello, do you have any screenshot/documentation link on what you call "scrgb" ?
Why is it not working ?

Thanks.
I am surprised the shader works with HDR at all. As of right now there is no option for output colorspace encoding, assuming a "sRGB - Display" (with a 2.2 power function) output.
Also if the same as HDR enabled I don't know what is going on in the reshade side, like what is the encoding of the game visual input ?

Then what is scRGB ? Never heard of it before and looking at Wikipedia it looks like a weird standard with a mention of not being intended for actual display.

With all of that I am not sure I can do much for your request. I don't have an HDR monitor for testing the support of the shader with HDR.
