Tomb Raider 4's PC port is fairly good. However one problem it has that Tomb Raider 2&3 lack is it has a windowed border in fullscreen that cuts off the health bar.

Thankfully this is very easily fixable. I'll include a download link to the fix bellow.

Here's the link

Go to your Tomb Raider the Last Revelation game folder. This is commonly located in

C:\program files (x86)\steam\steamapps\common\Tomb Raider (IV) The Last Revelation

It should look something like this


Now extract the contents of the download here.

Next run the file install.bat

and that should be it. Your game should run in fullscreen without the border.
