What I mean is, is it possible to change conf (?) settings to show no in game points on the score screen? Which file deals with point scoring?

This may be what you are looking for -> viewtopic.php?p=167174#167174

Also, is it possible to remove the 'enemy aircraft destroyed' message?

If you don't want to see any messages at all, do what Harnage said, if you still want to see some hud messages then open your hud_log_ru.properties file in Notepad/Wordpad and edit away or delete to your hearts content. One word of warning, when you open the file you will see two columns of data, DO NOT edit the left hand column, ie don't touch anything that I've highlighted in red in the screenie below.



You'll find the file in one of two locations;
IL2root\Files\i18n
or
IL2root\Mods\STD\i18n

Hope this helps

Cheers
