我的一些个人意见
angle对比dx和vulkan没有任何优势
关闭flip的dx性能也不如vulkan
dither我是真的一个像素点都感觉不出来区别
高刷屏+svp+interpolation+dither异常卡顿
关闭dither后正常
deband-grain我设置的12
32甚至24部分场景下可以感知到噪点
shaders_cache产生的频繁io对性能影响大于没有cache造成的影响
icc_cache产生的文件巨大，非常影响启动速度，同样有io性能问题
（sata ssd）
portable_config下可以再建一个fonts空文件夹方便使用
mpv可以读取这个文件夹下的字体
文件精简方面实际上只需要这些
svpflow的参数略微调整了下，不嫌麻烦的话可以帮忙测试下（原来不流畅的场景流畅了没有，什么场景出现了伪影）
