Talking about the challenges of bandwidth with the tech.
Huang says his voice is starting to go. Asking for water now.
Huang is still in good shape.
GameStream is a technology that is incredibly difficult to do. We've been working on this for some time. Still a long ways to go, but it's absolutely delightful today, Huang says.
We have the same tastes in clothes: jeans and polos.
Mentions Shield that connects wirelessly to PC. Using Shield in a game console mode with its lid closed, you can connect it to a 4K television, Huang says
Now talking Shield. Which was a bit disappointing when streaming PC games.
Range was just too short.
You can now enjoy your PC on the television, Huang says. Because people like to share their greatest moments on games today, it's not possible to capture your game play and share on Twitch, Huang says
Now possible with GeForce to capture your game and share directly to Twitch without hurting your frame rate, Huang says
You're going to enjoy a PC game, the latest generation PC game, DX11 called Batman on this 4K television, Huang says. Showing us a demo of Shield.
Nvidia employee is playing Batman on the TV, but game is actually running on the PC.
Wirelessly streamed to the TV.
Can enjoy next-gen games on your television, Huang says
Now seeing another demo of Shield gaming. Streaming game from PC right to the handheld gaming device
What's really fun right now is this server he's streaming from is in Sophia, France, Huang says
What we've shown you here is the Grid virtualized GPU server with the ability to serve games to hundreds of people at a time, across the ocean. 30 milliseconds for command to go across the ocean, captured in Grid, sent back 30 milliseconds later, Huang says
G-Sync is up next, Huang says
Invented to solve one of the longest running computer graphics challenges, Huang says. Still stutter and lag b/c no game or application where frame rate is consistent across every single frame. Sometimes more explosions, characters, multiplayer games, etc, Huang says
Fundamentally have this GPU delivering frames at a variable rate. Sometimes as fast as 100 framers per second. Other times as low as 8 frames per second, Huang says
We decided to create something fundamentally different.
Synchronize to the source, Huang says
Another demo - Starcraft II
Real-time strategy game where the gamer is managing assets, Huang says
G-Sync - monitor is syncrhonized. Only update the monitor when it's done with the vertical sync. Every so often it stutters b/c your'e sampling the frame.
Can solve this problem and make it smoother by adding more buffers. Double buffering and triple buffering. But it adds latency to the system, Huang says
Most gamers want so little lag b/c ability to compete depends on how many clicks they can make per minute. Some can click 300 times per minute. So they turn off V-Sync, compromising visual quality so they can be more competitive, Huang says
Reduces lag but has tearing of the image, Huang says
G-Sync. As soon as the GPU is ready, we're updating the frame, Huang says
The notion of tearing is gone but the lag is still incredibly low. Don't see stuttering that comes with V-Sync on and don't see tearing with V-Sync off, Huang says
