I've detailed the issue (massive CPU memory usage when attempting to use sparse textures) on Stack Overflow here but I'd like to ask specifically in the OpenGL forum. What do I need to do to establish my credentials and get access to communicate there?
Hi Brad,
You've been whitelisted now. I'm moving this thread to OpenGL forum.
Regards,
Thanks for the report. I'd appreciate if you could provide a buildable repro so that somebody from the GL team could have a look.
I've created a minimal example using GLI, GLM, GLEW and GLFW here: GitHub - jherico/gl_scratch
I've tested on Windows 10 using CMake to create a project using the following generator:
-G "Visual Studio 12 2013 Win64"
Thanks, I'll pass this to the GL team for further investigation. Will get back to you as soon as I hear back.
Can it have anything to do with the Dreadful OpenGL performance fix that you PMd me about back in October and that's still lacking?
mirh, if you're creating lots of individual 2D textures and marking them sparse, yes, that could be related. Try running you application and watching CPU memory usage over time.
Any progress on this?
