After being the first to find the sos console, now I bring another first to you guys.
You can finally play the Full game with the same bumpmap quality as in the demo and if you want you can have even MORE detail than you've had in the demo.
At this point you are probably asking yourselves how did I do it and if you will need to download some extra bumpmap files or something like that to fix it.
My answer is!
Absolutely not!
To get the bumpmaps to look as detailed as they looked in the demo or even more detailed all you have to do is enter this command in the console
r_bumpmipbias -1
Now read this if you want even more details or less details.
It seems that r_bumpmipbias is a lod (level of detail)setting for bumpmaps that can have values that range from -100 to 100 where 0 is technically the middle between extremely sharp and extremely blurry.
If you want the details to look as high as they did in the demo, type r_bumpmipbias -1 if you want even more detail type r_bumpmipbias -10 and if you want even MORE detail (which at this point starts to be exaggerated IMO) type r_bumpmipbias -100
If you want to go back to the default settings type r_bumpmipbias 0
To be honest, -100 vs -10 don't seem to make any real difference now that I've looked again and -10 already seems to exaggerated to me.
The thing with going too low with these values is that details start to look aliased(jaggy) and this is an effect that's know to happen when you exaggerate bumpmaps too much in general.
So my personal advice is to set them to either -1 or -0.5 according to your preference.
-1 is like in the demo while -0.5 is slightly blurrier but also helps with the aliasing issue.
Play with these values to your liking because this is where you get the bumpmap details from
