Input settings[edit]

Mouse acceleration[edit]

Mouse acceleration is tied to frame rate of the game, leading to extremely choppy control in periods of poor performance.[6]
Controller use

A controller will bypass the mouse acceleration problem.

Limit frame rate using Dxtory[7]

Using Dxtory to limit frame rate (for example, to 60 FPS) will limit mouse acceleration.

Issues unresolved[edit]

No shadows with AMD/ATI graphics cards[edit]

Prototype 2 has a similar bug as with Prototype, where shadows are not rendered properly on AMD ATI Radeon cards.[8]
This can lead to a very poor graphical quality.
There is no known fix for Prototype or Prototype 2.

Cannot complete Operation Flytrap[edit]

On some PC configurations it's impossible to complete the mission Operation Flytrap.
Set core affinity[citation needed]
  1. Alt+tab out of the game
  2. Open task manager,
  3. Find prototype2.exe
  4. Right click -> Set Affinity... and uncheck all but one of the checkboxes.
  5. Go back into the game and restart the mission.

Performance degrades over time[edit]

Prototype 2 has memory leak issues. The steps below help alleviate this.
Fix Data Execution Prevention setting

Ensure Data Execution Prevention (DEP) is set to the default (Windows programs and services only).

Alt+tab to release memory[9]

Alt+tabbing in and out of the game appears to release 500-600mb of RAM, delaying the onset of a memory leak crash temporarily.

Issues fixed[edit]

No voice audio during gameplay[edit]

Bug caused by Dolby surround setups.[10]
Set sound option to TV
  1. Go to options > audio.
  2. Set sound system to TV instead of Home Theater.

Glowing outlines on characters[edit]

Disable antialiasing[11]

USB devices crash game[edit]

Some keyboards (and likely other input devices) may cause Prototype 2 to crash while attempting to load the game (brief black screen, follow by a crash-to-desktop).
Devices with additional USB ports for connecting peripherals may be responsible for the problem.
Unplug USB devices

Unplug the device(s) before starting the game, then plug them back in.

Disable HID-compliant device
This may accidentally disable an input device.
  1. Open up the Device Manager.
  2. Disable one or more instances of HID-compliant consumer control device (not HID-compliant device).

Waypoints don't trigger and can't use airbridge[edit]

Seems to be sporadically caused by crashing in the middle of a mission
