 ## Does Magpie support touch input?
 
-No. Supporting touch input requires Magpie to have considerable high-level permissions, which is unacceptable for most users. Download the touch-enabled version from [#218 (comment)](https://github.com/Blinue/Magpie/issues/218#issuecomment-980506414).
+Supported from v0.11, see [About touch support](https://github.com/Blinue/Magpie/wiki/About-touch-support) for details.
+
+### Does Magpie support frame generation?
+
+There are no plans to implement frame generation. Magpie's goal is to improve visual quality, not performance, while post-processing frame generation is difficult to achieve a good enough result and adds latency. Game engines can use motion vectors and depth buffers to make improvements, but Magpie has no access to these. Similarly, FSR 2/3 are not on the development roadmap, as they need to be integrated internally and post-processing is almost impossible.

 ### 是否支持触控？
 
-不支持。支持触控要求 Magpie 拥有相当高的权限，这对一般用户来说是不可接受的。在 [#218 (comment)](https://github.com/Blinue/Magpie/issues/218#issuecomment-980506414) 下载支持触控的版本。
+从 v0.11 开始支持，详情见[关于触控支持](https://github.com/Blinue/Magpie/wiki/关于触控支持)。
+
+### 是否支持帧生成？
+
+目前没有实现帧生成的计划。Magpie 的目的是提高游戏画质而不是性能，后处理补帧很难达到足够好的观感，而且还会增加延迟。游戏引擎可以使用运动矢量和深度缓冲以进行改善，但 Magpie 不具备这种条件。与之同理，FSR 2/3 也不在开发计划内，因其必须采用内部集成，后处理几乎无法实现。
