Especially all kind of high iso pics are looking visibly worse after export.
I've already noticed that when I was digtializing grainy slides at ISO100, output was sometimes somewhat worse (more grain, lower detail etc.).
Is that normal?

RAW to JPEG, TIFF or anything else. Even without any compression.
@Orio
The Exports are looking worse compared to the display of the RAWs in Lighroom. Look at the pic I've uploaded. Some stars are missing/less bright and some color shades are also missing in the expot.
Today I will reinstall Windows 7 and install my new Lightroom 4. I hope the problem will be gone afterwards.

No, please do not start at that end (time consuming and irritating), and
I do not expect your problem to disappear afterwards.
Are you on Win 7 32- or 64-bit?
S-RGB, A-RGB, or...?
Which graphics card?
Is your monitor calibrated? With what?
I have Win 7 64-bit here, and Photoshop (CS6) 64-bit
(but not LR 4). If you like, I could perform a test run
here, if you agree that we in that way could find out
where the culprit is buried... |

In screen capture I see contrast difference.
I think matters for which output device LR is configured...screen capture looks like maybe output contrast is set for printing...paper has less DR than screen...

I formatted my PC, installed new 2x2GB Dual Channel RAM and (had 1x2GB before) Windows 7 SP1 64bit again and upgraded from LR3.6 to LR4.1
Now the problem is gone. 
Bye the way - Lightroom is also faster now!

Ah, good that you found a remedy.
However, Win 64-bit normally wants more
than 2 * 2 GB to be able to process photos.
Examples: when you try focus stacking, the
computer will lock up after only a few photos; HDR
processing is out of the question, and so on.
I put in 12 GB -- now Photoshop, the focus
stacker, the HDR algoritms and I are happy.
Er... better check: it might depend on which Win 7
version you have -- I have a faint memory that
all versions cannot handle the same amount of RAM.
-- a little later --
Yes, I was right. Here are the maximum amounts of
of RAM that Win 7 64-bit versions can handle:
•Starter: 8GB
•Home Basic: 8GB
•Home Premium: 16GB
•Professional: 192GB
•Enterprise: 192GB
•Ultimate: 192GB
Another limit is, of course, what the motherboard
is built for. |

I have Windows 7 Ultimate and when I bumped up the stock memory from 4 to 16Gb Lightroom was amazingly fast. That goes for all the plugins I use too, it was a revelation that blew me away.
