"being worked upon" - it might be at Comic-Con.
The demo became available on Xbox 360 for those who owned Dragon's Dogma. It's a widely reported issue from gamers over in camp Xbox. Beans to spill soon on Ada Wong's RE6 role.
"Xbox 360 screen-tearing has been noticed, and is being worked upon," said community manager Elston. The exec was unsure if the problem made it to Comic-Con.
Resident Evil 6 on Xbox 360 right now has little regard for v-sync, meaning its framerate doesn't play nice with a screen's refresh rate leading to the screen-tears. Apparently fresh footage of Chris Redfield and Jake Muller's campaigns were aired without the issue, so it looks like Capcom nipped it in the bud for the San Diego trip.
Fans have spotted files in the RE6 demo pointing to Ada Wong having a prominent role, to the tune of having their own separate campaign. "Ada has a large role in the game. We'll be ready to spill the beans soon," teased Elston.
