Intel has released a brand new graphics driver for its Arc GPUs which focuses purely on enhancing synthetic benchmarks performance and not games.

We have been told by Intel officially that Intel's Arc GPU drivers are the main cause of delay for the lineup. The poor software readiness means that although the hardware is already built and ready to ship to consumers, the blue team has to delay or launch the lineup in selective regions to avoid any major backlash from the poor performance and software ecosystem.
