PlayonLinux and World of Tanks?

[PNWDrew]

Anyone got any tips on getting WOT to run well with PlayOnLinux?  I've been trying to solve this for several months. I'm having strange rendering issues like technicolor tanks and flashing/flat landscapes.  Sometimes the tank sinks into the surfaces, sometimes it just disappears. White landscapes are the worst for some reason.  The graphics problems make the game unplayable in snowy maps.

I've seen references to it running better as 32bit, and lots of "tweaks" in various forums; however randomly tweaking settings seems like a sure way to bork it since I know so little.
