听说最近又出了一个逼真的crt滤镜，我又来试试呢

dollet

    效果如何你们来说，我的设备有留意这个论坛的都应该知道的，lg 65 c8p oled ，14次渲染。可能需要点开大图看

效果逼真，65寸当然比14寸彩监爽的多。当然彩监党该不服还是不服。14次渲染啥滤镜？

     就是CRT-royale  好像是你分享过的，只是你那个是12次渲染，我这个是14次。最大是26次。不过26次好像要自己慢慢设置的，不太懂

求滤镜文件 可以分享吗

There are a huge number of parameters.  Among the things you can customize:
* Phosphor mask type: An aperture grille, slot mask, and shadow mask are each
  included, although the latter won't be seeing much usage until 1440p displays
  and better become more common (4k UHD and 8k UHD are increasingly optimal).
* Phosphor mask dot pitch
* Phosphor mask resampling method: Choose between Lanczos sinc resizing,
  mipmapped hardware resizing, and no resizing of the input LUT.
* Phosphor bloom softness and type (real or fake ;))
* Gaussian and generalized Gaussian scanline beam properties/distribution,
  including convergence offsets
* Screen geometry, including curvature (spherical, alternative spherical, or
  cylindrical like Trinitrons), tilt, and borders
* Antialiasing level, resampling filter, and sharpness parameters for gracefully
  combining screen curvature with high-frequency phosphor details, including
  optionally resampling based on RGB subpixel positions.
* Halation (electrons bouncing under the glass and lighting random phosphors)
  random phosphors)
* Refractive diffusion (light spreading from the imperfect CRT glass face)
* Interlacing options
* etc.

这个滤镜RA中自带，
作者已经在开发文档中提到：这个滤镜各种CRT参数可以高度定制，并且在2K,4K,8K显示器上有极佳的表现，分辨率越高模拟越好。等以后8K UHD大尺寸电视和显示器普及后模拟老游戏都能有比彩监更佳的表现，还要啥14寸小彩监啊，

如何使用啊

iBiohazard6

用LG OLED65G7P的飘过，4K电视上用这种滤镜眼睛不会很难受吗？

说实话我还是比较喜欢在真正的CRT上怀旧，4K电视还是用来看片儿最舒服了。

覆层没有延迟，滤镜就呵呵了，14通道不容乐观

如何使用啊

retroarch里的shader目录下，GLSL分类里进CRT目录，选crt-royale.glsl。对pc机能有要求，推荐i5+750ti以上配置可全速运行不卡顿，同时需最少2k显示器配合，4k显示器更佳。
