While at BlizzCon, we took the time to check out the latest offerings from video card giant NVIDIA. And while a high-end graphics card can certainly improve the look and the framerate of WoW and other games, we were intrigued by a couple of new features NVIDIA was showing off: G-Sync and ShadowPlay.
G-Sync is a new way for your monitor and your video card to talk to one another -- and though they aren't on store shelves just yet, you can expect monitors from brands like Asus and Phillips to have G-Sync built-in by early 2014. What's so important that it would be worth buying a new monitor for? G-Sync addresses framrerate differences between your monitor -- which refreshes at a fixed rate -- and your video card -- which doesn't. When your video card tries to send data to your monitor more quickly -- or more slowly -- than your monitor wants, you'll see graphical stuttering or tearing. Monitors with G-Sync work with your graphics card to keep things in, well, sync for a perfect graphical experience -- whether you're running at ideal 60FPS or dropping down to 20FPS in a crowded auction house.
