				/* Defines the number of simultaneous command buffers which can be in flight.
				* The default limit of `64` is considered to be optimal for Blender. Too many command buffers
				* will result in workload fragmnetation and additional system-level overhead. This limit should
				* also only be increased if the application is consistently exceeding the limit, and there are
				* no command buffer leaks.
				*
				* If this limit is reached, starting a new command buffer will fail. The Metal backend will
				* therefore stall until completion and log a warning when this limit is reached in order to
				* ensure correct function of the app.
				*
				* It is generally preferable to reduce the prevalence of GPU_flush or GPU Context switches
				* (which will both break command submissions), rather than increasing this limit. */
