Re: [Opengc-devel] Performance Issue( help!)

Hi,

One question comes to mind immediately.... you mentioned that you 
"altered the app update rate appropriately". Was that modification of 
this line:

appUpdateRate = 1.0 / 24.0;

in main.cpp?

If you set this to be 1/1000 what happens? Also, you mention removing a 
piece of debug code - could you be more specific? Is this a debug or 
release build?

Thanks,
-Damion-
