I guess to be safe, I'll just disable multi-threading of gfx components if the user ticks the "Enable AMD Extensions" box?
I got this answer on Git Hub
The DX11 driver extension functions will not work for deferred contexts (#4). I'll make sure to mention this in the documentation.
For the AMD driver, deferred contexts don't buy you any additional performance and we recommend against using them! You are much better off multi-threading your rendering and writing each thread's output to a software command buffer which gets processed by the immediate context on the main thread.
