I have been testing out both the Autodesk and regular Windows AMI's.

The streaming performance / latency doesn't seem to be much better than RDP.

Is this expected behavior with the current versions of the AMI's?

No, you should be getting 60 fps. What browser/OS are you using, and what is your bandwidth?

Can you provide a screenshot with the status showing your stream fps/rtt etc.?

Attached is screen capture.

Running Chrome 30, Windows 8, on an AMD APU.

Firefox is a little better but similar performance.

Bandwidth should be ample.

You're right, bandwidth isn't the issue here, it's the decode time. You are decoding in ~27 ms, so that is limiting you to <40 fps. Typically each free physical CPU core on your system can handle about 720p30 via ORBX.js. What is the CPU config/speed/corecount of your system? Also make sure you don't have any extra tabs running in the background, as those can also eat up CPU cycles if they are running canvas/flash etc.

I am going to work on a simple substitute native launcher URL this week (that works with identical GUID, command line, etc.), and I'd like to have you retest using that in place of the JS client. This way we'll confirm if JS decode speed is what is dropping you below 60 FPS.

Thank you for the feedback. This is very helpful.

How do you pull up those figures out of interest

Based on broad testing of current Gecko/Chromuim browsers on mid range x86 PC's and laptops.
