The game screen is inundated with graphical glitches. It's hard to describe except to say that the game seems to be drawing multiple giant triangles or different colors and sizes across the entire map, blotting out anything underneath them.  they're all directional, so it's almost like it's drawing the light source, or something.

It starts with the game as soon as everything gets drawn, repeatably.  There's a moment where I can see my sovereign surrounded by white and then once the FoW goes away... boom, triangles!

Big screenshots follow:

Tried turning off shadows, using shadows at the highest and lowest settings.

Tried turning off anti-aliasing.

Tried turning off particle effects.

Tried various combinations of all these things.  No effect.

Changing my settings doesn't do anything. 

I've been having this issue since the late-stage betas (0.98) but I figured it had to do with HP not updating the graphics drivers since January.  Lo and behold, HP released updated drivers for my machine on Aug 18th -- so my drivers are now from June .

The problem persists in 1.05 with the latest drivers for my system.  Currently I am trying uninstalling and reinstalling (whee another 1.8GB download).
