If you divide the Texture, you'll not reduce the amount of data that the client has to send. For an Image with 720x640 size, 1.3 MBytes has to be transfered. With Fast Ethernet you'll get a maximum of 7 frames/s If you network is not able to send a whole image for each frame, you could try to send compressed images. But it is difficult to compress images fast enough. Marcus > > _________________________________________________________________ > 증권 정보 가장 빠르고 편하게 보실 수 있습니다.
