Re: powerplant model on chromium

Have you tried splitting the model into LOTS of small display lists?  I 
wouldn't be surprised if Chromium borks on massive lists.  You can also 
play with the tiling mode to attempt to reduce the network load.  
Although, 100Mbps is always going to be a problem past a handle of nodes 
if there is much traffic on the network.  Without display lists, all the 
geometry is going to be resent every frame...
