😮
I wasn't ready for this, I'm shook!
Can't wait to try the above build.

I'm unable to see a difference between medium and high, as below. If these are the intended shades, could we possibly make Low the default setting? I feel med/high would be too dark to offer as default, and low is closest to OG PC.

On med/high the title screen text is difficult to read.

@lahm86 did you upgrade the shaders? It's not supposed to look dark.

My bad, I built locally and didn't copy those over. Can see the difference now, thanks.
I still prefer Low I have to admit 😄 Flares when on the snow hurt my eyes in med/high, but that could just be me.

We need to replace the red eyeglasses with this item:

:D

I'd leave it as high or maybe medium as middle ground, to increase this feature's visibility. It's more likely that people who dislike it will look for an option to change this, rather than them looking for an option they might not know exists.

Ha, snow goggles would be good 😄
I think going with medium would be a good move, but happy to go with what the majority think on this. Functionality-wise, it's great 👍

Thanks – I've changed it to medium. I'll wait for aredfan's approval before merging.

Thank you for waiting, I appreciate it. I've tested the different lighting contrast modes and everything LGTM. 👍
