Mouse acceleration[edit]

Fix Controller use

A controller will bypass the mouse acceleration problem.

Fix Limit frame rate using Dxtory[7]

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

No shadows with AMD/ATI graphics cards[edit]

Disadvantage This can lead to a very poor graphical quality.
Disadvantage There is no known fix for Prototype or Prototype 2.

Cannot complete Operation Flytrap[edit]

Information On some PC configurations it's impossible to complete the mission Operation Flytrap.

  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]

Information Prototype 2 has memory leak issues. The steps below help alleviate this.

Fix Fix Data Execution Prevention setting

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

Fix 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]

Information Bug caused by Dolby surround setups.[10]

Fix 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]

Fix Disable antialiasing[11]

USB devices crash game[edit]

Information 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).
Information Devices with additional USB ports for connecting peripherals may be responsible for the problem.

Fix Unplug USB devices

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

Fix Disable HID-compliant device

Disadvantage 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]

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

Fix Force a reload of your character by evolving

Evolve by consuming/finding collectibles to proceed with missions.
