Top 10 opengl es 2.0 apps1/23/2024 ![]() ![]() Thanks for testing I'm working on some more OpenGL ES 2.0 feature tests right now. Vulkan is a low-level graphics API developed by the Khronos Group, the same organization that. What does this imply? Am I bus bound? I thought I'd need to hit near 100% utilization in at least one of those three statistics before seeing the fps drop (and yes, the app can hit 60 with very simple scenes).Īt the moment, all the app is doing is render a scene graph containing 500 untextured cubes with normals, bunched into groups of 1 to 6. OpenGLES1.x test app was easier to develop because of the software renderer which works in the emulator (so you didn't need a real device). One alternative to OpenGL for Android development is Vulkan API. The app (running on an iPhone 3GS, iOS 4.2) runs at about 15 fps, but Device Utilization is only around 40%, Renderer Utilization around 35%, and Tiler Utilization below 10%. I started profiling in Instruments (Xcode 3.2 I do have access to Xcode 4 through the iOS dev program, but refrained from using that because of some strange behavior), but I can't quite make sense of the data: I'm making some progress, but the performance isn't that great anymore. I only knew the basics of old-fashioned OpenGL (without shaders) before, but I can do (and did implement) some basic Matrix and Vector math. So, yes, I'm learning that at the same time. As my first project, I've chosen to write a small 3D app for iOS, using only OpenGL Es 2.0. ![]()
