PSVR 2 Can Be Used on a PC Without an Adapter If You Have a Compatible Graphics Card - Road to VR
PSVR 2 Works on PC Without the Adapter If You Have the Right Graphics Card
Sony has launched its highly anticipated PC VR adapter for PSVR 2, but early reports indicate that some users may not need the $60 adapter to play PC VR games like Half-Life: Alyx. Certain graphics cards with USB-C ports, particularly those supporting the discontinued VirtualLink standard, allow direct connection to GPUs and access to SteamVR games via the PlayStation VR 2 App on Steam. These compatible graphics cards include some Nvidia GeForce RTX 20 Series cards and AMD reference design cards from the 6000 or 7000 series. However, this setup might come with limitations such as connectivity issues with PSVR 2 Sense Controllers and the absence of PSVR 2-specific features like HDR and eye-tracking.
