Abstract: "Cloud gaming provides game-on-demand
(GoD) services over the Internet cloud. The goal is to
achieve faster response time and higher QoS. The
video game is rendered remotely on the game cloud
and decoded on thin client devices such as tablet
computer or smartphone. We design a game cloud with
a virtualized cluster of CPU/GPU servers at USC
GamePipe Laboratory. We enable interactive gaming
by taking full advantage of the cloud and local
resources for high quality of experience (QoE) gaming.
We report preliminary performance results on
the game latency and frame rate. We find 109 ~ 131 ms
latency in using the game cloud, which is 14% ~ 38%
lower than 200 ms latency experienced on a thin local
computer. Moreover, the frame rate from the cloud is
25% ~ 35% higher than that of using a client computer
alone. Base on these findings, we anticipate game
cloud to have a performance gain or QoS improvement
of 14% ~ 38% over video gaming on a thin client
device such as a smartphone or a tablet computer."
