How about nebulaes and milky way galaxy clouds from a distance?
I'm in colonia, which is very dense in stars, and it looks infinitely better, gas clouds look like gas clouds, the nebula colour gradients looks good, I've turned the gamma right back down to around 15-20% and can only see a hint of banding if I look really hard, yesterday I had it up to 80% and could still see banding. Around star coronas, I can't see any at all.
Huge improvement in my headset, only thing is, now the gamma is back down, god rays are more apparent.
To a previous post, I've not noticed any rise in my temps, sitting around 60 degrees on a 980ti.
