I want to set GLX_CONTEXT_PRIORITY_LEVEL_EXT when create context glXCreateContextAttribsARB. But it seems that the extension GLX_EXT_context_priority is not supported now. Is there any method to solve this problem.
My SteamOS version is 3.4.11 Graphics Processor: AMD Custom GPU 0405
I use glxinfo | grep GLX_EXT_context_priority and get nothing returned.
