I really would like to know if the Arc-4-Xe-cores iGPU - which officially is called only "Intel Graphics" - profits from the same graphics drivers, or if the profits only apply to the official Arc-7-Xe-cores and Arc-8-Xe-cores iGPU. Unfortunately there hasn't been anyone testing that...
It's the same generation (the same product family if you like). Of course lower-end parts get the same driver improvements as higher-end ones.
Either way I bet Intel will never be as good as Nvidia at gaming. It needs to start sponsoring big releases asap
