Mirror's Edge DLC map converter

This is simply a patched .exe from the Steam version of the game that resolves the performances issues, it saves you having to do the hex edit yourself.
I don't believe it works for the GOG version, but you're welcome to try it out for yourself.
 

The Steam version of FlatOut is the v1.0 version. This is the v1.1 patch for FlatOut that works with the Steam release. GOG is already patched to v1.1, and does not need this patch.
Originally posted by Clya900, the patch was missing 2 files are now included in this download, patch1.bfs, and patch.ini. Without these files, the game would fail to load, and shows a Runtime error. The game now has been tested on the Steam version, and works perfectly fine.

Why is this game lagging when steam is in online mode? Everytime in the menus too. It drops to 1 fps for 10 seconds and that repeats. Whenever I go into offline mode this problem dissapears. But why does this game work like this?

There's a little reported bug with the GOTY version on steam that causes some DX11 point lights to not blend correctly and show their polygonal edges.
Here's the steam thread with the fix:

And the fix itself in a google drive link: https://drive.google.com/file/d/0B60dyrffWO_PNU50N0h3bE9fZkk/view?usp=sharing
Visually the issue is very noticeable when looking at Tyger helicopter searchlights and the first room in the museum with the TVs pointed at Batman, they look like giant polygonal shapes that brighten anything within or behind them from your POV.
The fix replaces two shader files that were sourced from the original GFWL release, the steam version's ones are the culprit. If someone could archive these and add a link and description on the wiki page that would be great.
Unrelated, but I was trying to post this on the arkham city discussion page but captcha kept on resetting after pressing add topic, sorry I just made the account to try to put it on there so if I did something wrong my mistake.
