CRT shaders: Made the section a bit less confusing, hopefully
===CRT shaders===
These replicate Aperture Grille aperture grille CRTs. These , which have sharp images and strong scanlines. ShadowIf you find that this doesn't look a damn thing like your old TV, it's probably because you owned a shadow-mask CRTs are far more common. Howeverstyle CRT, which has no scanlines (the easiest way to tell the difference is to replicate that that one would need a very high resolution display (4K or around therefeel the curve of the screen; aperture grilles only curve horizontally if at all). For this reasonUnfortunately, shadow masks require resolutions of upwards of 3000x4000 to emulate accurately, shaders replicating Aperture Grille CRts are so all that we will see have for the time beingare aperture grille shaders.
Use integer scaling. This means either using windowed mode (x2,x3,x4) or setting an integer scaling option in the video options. The reason is that non-integer scaled scanlines will result in uneven lines with artifacts.
