NVIDIA has just updated its game streaming service to add support for 1440p resolution at 120 frames per second in a Chrome or Edge browser. If you're part of the RTX 3080 tier, you can access the new browser gameplay option by simply tapping on 1440p on the GeForce Now web version.
NVIDIA launched this membership tier last year to support streams of up to 1440p with 120fps on PCs and Macs or 4K HDR at 60fps on NVIDIA's Shield TV. But you can only access this feature if you use the dedicated Mac or Windows apps. The web version maxed out at 1080p at 60fps before.
