Tried with WAN=7, no visible improvement.
On my side, it's ThinkPad W520 laptop, with Quadro 2000M graphics card, and with kernel 3.10.17 and latest NVIDIA drivers installed; all of this working properly. My browser is Firefox 24.1.0, when I visit get.webgl.org I can see spinning cube, so I guess WebGL is working fine with my browser. As mentioned in my previous post, I'm using Octane Cloud Workstation (Linux) AMI, and when I connect from my browser, the desktop size is 1024x768.
As far as clients to access remote desktop concerned: what is with this NVIDIA GRID VCA Workspace client shown in some of GRID marketing videos? Would it be possible to connect using this client, and is this client available at all?
Also, any comments on my question about additional steps needed to configure Amazon Linux AMI with NVIDIA GRID GPU Driver to enable remote access, like Octane Cloud Workstation (Linux) AMI is doing?
