This often happens because CrossOver and Guild Wars 2 are not properly communicating with each other about how much Video RAM your system has (more than likely, CrossOver is not getting the correct value from your system).
You may need this setting if you have the following symptoms:
Strange rendering
Crash/Freeze on launch
A log file that says something like:fixme:d3d_texture:texture_init Failed to create surface {some value}
err:d3d:resource_init Out of adapter memory
Linux:
1. Open a terminal (often ctrl+alt+t works)
2. Give this command*:

3. Locate the line that states "Memory at d0000000 (##-bit, prefetchable) [size=###M]
4. Remember the "size=" value
5. In terminal run:
/opt/cxoffice/bin/cxrun
