2. Locate the folder ...My Documents/Bioware/Mass Effect/Config/ and make a copy of your BIOEngine.ini file.
3. After you made your copy, move my downloaded file into this folder.
4. My file enables a few ingame settings that were originally disabled, which help better graphics and performance. Results may vary for others depending on your system. If you experience any lagging or crashing, delete my file and result back to your original copy from step 2.
