Graphics not very good

[Geckomeister]

Hi,

I am new to IL-2 so bear with me.
I bought IL-2 1946 on steam, and the graphics seem pretty crap,
The ground textures are all blocky, and not as nice as a lot of the screen shots I have seen floating around.
I have pumped up the graphics to its highest level, and it's a little better, but not really that impressive.
Am I missing something here?
Is my expectation too high?

Also I am running 4.09m with steam, how can I upgrade it to 4.11 to get access to the latest features?

Cheers
Gecks
