The buffer is a GL_SHADER_STORAGE_BUFFER composed of 300.000 float values. The transfer operation with glGetBufferSubData is taking around 10ms, and with glMapBufferRange, it takes more than 100 ms. The code Im using is the following: std::vector<GLfloat> viewRow; u...

字符集 glGetBufferSubData()的target参数应该指定绑定点,而不是缓冲区对象。请尝试GL_ARRAY_BUFFER:
