I just gotta ask, how does it sync the screen? Do you just send screenshots now and then, or do you encode a video stream?
Basically it splits the screen up into blocks, and sends jpeg screenshots of each block every so often, with the block that contains the cursor getting the highest priority.
Encoding it directly into a video stream probably won't make all that much of a difference speed wise, given that its still transfering pretty high resolution images.
What does it look like without the AA enabled? I haven't really used DNB much, but I haven't really had a problem like that using Krypton Suite
I'm not using Krypton, nor have I had much experiance with it. Its probably handled differently in DNB.
