GPU passthrough requires a hardware video output for the discrete GPU. You can go looking through the moaning of Oculus Rift users[1] as they prowl laptops that do this, but it&#x27;s pretty much unheard of in current standard laptops.<p>[1] Rift needs better video latency than you get with routing the DGPU output through the IGPU. Apparently there are now some specialized 17&quot; gaming laptops that support a &quot;direct mode&quot; that might allow GPU passthrough to HDMI given software support.
