<pre>The bufferSubData is likely uploading my giant UBO for the frame. Either that or vertex data for some dynamic draws. All uploads happening every frame should be marked GL_DYNAMIC_DRAW (which I believe should be correct? Can never remember the difference between that and GL_STREAM_DRAW), and I try to keep UBO data limited to 65536-sized buffer pages.
If there's anything I'm doing wrong on my side, please let me know.</pre>
