Yes, there is a SM5 extension to reduce the impact when you're on a high-end Windows PC. But for most games, relying on that is not really practical, or else you lose Linux, Mac, most consoles and mobile.
I agree that impostors are great for far-distance background. But I would never use them for anything too close to the camera. So in a sense, impostors are the new skybox.
- bgolus 6y agoVulkan & Metal both have equivalents, at least for Linux & MacOS. As do most modern consoles. Mobile is an issue, yes. Though curiously sphere impostors were first proposed for use with and implemented using GLES 2.0 for a significant performance and quality improvement in drawing thousands of spheres for molecular rendering. It all depends on what your use case is. Also hardware with Shader Model 5.0 support came out >10 years ago now. There aren't a lot of desktop computers still using hardware that don't support it.
