Question about HDX performance.

Question about HDX performance.

My company has decided to go with Citric VDI-in-a-box for desktop virtualization and I am currently testing out thin clients. I currently have a Wyse T10 and even though I have tweaked the settings as to receive a 10/10 on the HDX monitor software, I find the performance lacking. The quality is excellent but the FPS is rather low and the screen gets very choppy.

My next thing I am about to look at is the Xenith Pro. Will this help out HDX performance? The other suggestion I've gotten is the R10L, but after setting up the T10 I am very interested in going with a Zero Client solution to minimize hardware setup.
