Whenever I`m not holding a gun, I get around 100 FPS with shaders on. As soon as i hold the on, my FPS drops to around 35-45.

补充：与oculus或embe有冲突，vic的枪械也有同样问题，具体表现为手持有瞄准镜的枪光影会错误，刷新后虽然能回复正常，但帧数会大幅度下降，

Rendering issue is common in mc mod who use high quality model. We are now trying to solve this problem with a new rendering pipeline
