Welcome to the tweaks guide for Mass Effect 3. Technically, Mass Effect 3 uses the exact same engine as its predecessors, and has moderate to low system requirements for running.
For those looking to maximize the visual aspect of the game while knowing their system’s performance won’t be hindered, it is recommended that they have a look at their configuration through the Mass Effect 3 Configuration utility found in Mass Effect 3\Binaries. If everything is maxed and you still desire better visuals, have a look the detailed tweaks that follow shortly in this guide.
For those looking to maximize the performance while sacrificing the visuals, a good method to start off is by actually reducing or turning off in-game available variables such as anti-aliasing, reducing general resolution, and/or reducing Spherical Harmonic Lighting and Anisotropic Filtering options.
If you’ve done all that, and are still not satisfied with the output, be it visuals or performance, then have a look below for some additional options that aren’t available conventionally:
Mass Effect 3 – Anti-Aliasing
Mass Effect 3 does already offer anti-aliasing by default, but some people prefer even better anti-aliasing, as the default doesn’t entirely remove the jaggedness and may also blur the screen. This is possible mainly through the drivers and other related software for your graphic card.
For Nvidia users, the Nvidia Inspector is a great tool for doing this. You can download it from here. Also, make sure you have the latest drivers for your card, as the Mass Effect 3 profile is unavailable in the older versions.
Next, launch the Inspector after installing it and click the ‘Driver Profile Settings’ button. A window will open. View the profile drop-down menu to find Mass Effect III, and select it.
Once that is done, edit the ‘Antialiasing Compatibility’ setting and select ‘0x080100C5 (Mass Effect, Mass Effect 2)’ option.
Then, select ‘Antialiasing – Behavior Flags’ setting to ‘None’, and for ‘Antialiasing – Mode’ select ‘Override any application setting’.
Next, at the ‘Antialiasing – Setting’ select the desired AA mode (higher severely reduces performance but greatly increases visuals).
Apply Changes and make sure to turn the in-game AA settings OFF to prevent conflicts.
Mass Effect 3 – How To Change FOV
The field of view is general amount of visible world on-screen. The default in Mass Effect 3 is 70 degrees. This is absolutely unchangeable in the game itself. However, there is a way around it.
Download and extract the latest version of Widescreen Fixer. Make sure it is the latest version as previous versions do not have a profile for ME3.
Next, make sure ME3 and Origin (if running) are closed. Run the widescreen fixer utility and select the game from the drop-down menu. Go to the settings and assign a suitable hotkey for to trigger the FOV fix.
Now, click the Cog icon next to the Select Game box and select a new field of view for ME3 from the ‘Vertical Field-of-View in degrees’. Once finished, close the window.
