Hello, because I can't get help from from anyone of my polish game-sites I ask here ;)
My computer is:
Intel E5200 (2.4GHz)
4 GB RAM
GeForce 9600 GSO
Win 7
with all drivers updated
before installing a full version I've installed a demo which had the same restrictions in options (that you can see on attached screenshot). But I thought that was typical for demo.
The screenshot becomes from full version - I cannot change grphics to medium, high or even turn on shadows. In fact my game looks ugly and I don't want to play it until I'll fix it.
Could anyone help me?
Thanks!

Did you make sure to fully remove the demo before installing the full version? Also are you running the shortcut as admin?

Yes, I removed but like I said - demo had the same restrictions like on screenshot. I installed it on the other machines, better, similar and worse and it's running ok. (all have Win 7).
Yes, I used admin setting.

It could be a left over registry setting depending on how sloppy the programing for the demo was or if any problems occured while uninstalling the demo. If you know your way around the registry? If so I would advise uninstalling the game again and then going into the registry and making sure it has no settings left over and then reinstall it.

Yes it could be but it isn't. Uninstalled the game, cleaned registry, installed again and it's the same. On the other machines even in demo I can set up the best graphics.

De-update your drivers :)

I had the same problem and reverted back to the very first Win7/64 drivers, 195.62-WHQL.

Tadaaa! Somewhere between 195.62 and the latest version Nvidia changed something, so that the game is no longer able to proper recognize the GPU hardware. Try some older driver versions, 195.62 will work for sure. At least, it did for me.

Thanks, I'll try that in future and post back if it worked or not :)
