发现 archlinuxcn 里面已经打包了很多模拟器,小到 NES/SNES 模拟器,大到 PSP/PS/PS2/PS3 模拟器等。
对于这类模拟器软件,性能对用户的体验至关重要。
目前,archlinuxcn 打包的所有此类模拟器软件均未开启 AVX/AVX2 指令集。以 Dolphin Emulator 为例,从 archlinuxcn 直接下载的版本(未开启 AVX2)与自行开启 AVX2 指令集编译的版本,实测在同一个游戏中的模拟帧率差距可达 40%。
参考 Arch Linux 官方的打包,有两组包比较典型:一个是 tensorflow/tensorflow-opt,另一个是 python-pytorch/python-pytorch-opt——有无 -opt 后缀的区别在于是否开启了 AVX2 指令集,这样的命名规则可以参考。
