Prototype 2 (PC) Errors and Fixes Guide


Like many other games, Prototype 2 launched late on PC. The game is out now for PC gamers and the fans must be enjoying it already. But, there might be some PC users out there who couldn’t manage to run the game properly due to some game breaking bugs and other technical issues which we will fix in this Prototype 2 Errors and Fixes Guide.

Prototype 2 Errors and Fixes

If you are among those unlucky few, follow our workaround guide to fix the most common issues.

#1 ‘Prototype2.exe’ has stopped working
To resolve this issue, you can try out the following methods:

  • Try running the game as “Administrator”.
  • It may be due to some hardware plugged into your PC. Try unplugging them one by one and see if the game gets started.
  • You can also try adding “-window” or just windowed at the end of shortcut file to run the game. Add the parameter at the end of the command line of the shortcut.

#2 FPS Drop Fix
If you have been experiencing drastic drops in FPS then you can try out the following fix to resolve the issue:

Put the command as launch options in steam “windowed windowwidth=1920 windowheight=1080” without the quotes.
Launch the game again to see difference. And if your PC is not good enough to run the 1920*1080 resolution then you choose the lower resolution value.

#3 How to Fix the Refresh Rate Problem
Just like the FPS drop fix, you need to add the command “RESOLUTION=1920×1080@60” in the Steam Launch options. This will give you the appropriate refresh rate in the game.

#4 Mouse Fix
If you are facing the mouse lag then it is recommended that you try out these drivers for AMD cards. The mouse lag must be refined at least till you restart your PC.

#5 Prototype 2 – Game is Stuck During a Mission
You may face the issue especially during the early tutorial session of the game. In that case, you can do the following:

  • Press Alt+Tab to minimize out the game.
  • Open Task Manager and select the processes tab.
  • Right Click on prototype2.exe and click set affinity.
  • Make sure that your CPU is selected as ‘0’.
  • Press Alt+Tab again to start playing the game normally.

#6 Prototype 2 Shadow Rendering Issue
The same issue as was found in Prototype where he shadows don’t seem to render properly which also results in render lag. This happening only with Radeon Graphic cards and as for now no fix has been found.

#7 Cannot Complete Mission Flytrap
On some Pc configuration you can play this mission but lucky there is an authentic fix. Just do the following:

  • Set Core Affinity by going to Task bar and then right click on Prototype2.exe, Set affinity and Uncheck all but one of the boxes
  • Turn the in-game Vsync on and set the refresh rate to 60Hz.
  • Go back to the game and restart the mission.

The game seems to have a memory leak issue which can be fixed by:

  • By setting Data Execution Prevention to Default
  • Alt+tab in and out of game to release some memory

#9 Unplayable Frame Rates on AMD Card
Apparently if you are using Crimson Driver you will not find the game payable at all. This happens due to Catalyst interfering with the game so you have to disable the catalyst as follows: For Window 7

  1. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000 (or 0001)\UMD\.
  2. Change the CatalystAIvalue to 30.
  3. Change the CatalystAI_DEFvalue to 0.
  4. Save the changes made and launch the game.
  5. If the fix does not work, try restarting the computer and launching the game again.

For Windows 8+

  1. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000 (or 0001)\UMD\.
  2. Change the CatalystAI_DEFvalue to 0.
  3. Save the changes made and launch the game.
  4. If the fix does not work, try restarting the computer and launching the game again
