This page says that coarse synchronization is used to prevent concurrent thread device access.

Can I design a multithreaded resource loader with only multithreading in mind and expect that the cards/drivers that don't support it will serialize the resource creation? I can't be sure, but it seems like I have heard stories of this causing crashes on drivers without support for multithreaded resource creation. 

 

Can anyone confirm this? I don't have a system that I can try it out on!

In theory everything should work fine, since the runtime itself will synchronize to prevent the driver from having concurrent resource creates if it doesn't support it. But I've never tested on a driver that didn't support concurrent resource creation, so I can't verify anything.
