最终渲染场景的图形硬件由称为着色器的专用程序来控制。硬件的功能已在不停进步,伴随每个阶段产生的一般功能集称为 Shader Model。不断更新的 Shader Model 可以支持更长的程序、更强大的分支指令和其他功能,并且这些特性已经让游戏的图形性能得到改善。
Unity Editor 可以对多组 Shader Model 和图形 API 限制进行仿真,以便快速了解在特定 GPU 或图形 API 上运行时游戏的外观概况。请注意,虽然Editor 内的仿真非常近似,但是仍然建议在目标硬件上实际运行游戏程序。
要选择图形仿真级别,请选择 Edit > Graphics Emulation 菜单。请注意,可用选项会根据您在 Build Settings 中当前设置的目标平台而不同。您可以通过选择 No Emulation 来恢复硬件的完整功能。如果您的开发计算机不支持特定 Shader Model,则该菜单项将被禁用。
