开发组发布说明原话New launch parameter "-nomtex". Disables multi-texturing and enables texture sorting. This can be useful for players with lower end hardware (i.e. Intel HD Graphics) if they are experiencing performance issues on maps with dynamic lights and/or when using the flashlight. Dynamic lights still work in this mode but detail textures are not available. This can be a better option than disabling dynamic lights completely by setting "r_dynamic" to "0".
