Known Issues

Black screen on Prototype start up

For Windows XP, Windows Vista and Windows 7 users

  1. From the start menu, Click on Run then type “dxdiag”
  2. Click on the “More Help” Tab then click the “Override Refresh Rate” Button.
  3. Set the refresh rate override value to 60.

Sound stuttering, cracking aka Chipmunk audio

  1. Go to your sound card’s control panel.
  2. Locate the option that allows you change the default audio format for the card.
  3. Set the default format to 24-bits, 48000Hz or less (if it doesn't work with 48000Hz, try 24 bits, 44100Hz)

Display Issues

Most display related issues are caused due to outdated software. Make sure to update the display drivers and DirectX to solve most of the dll missing errors along with a few minor in-game issues.

Missing textures

  1. Disable Anti-aliasing (AA) in Prototype’s video options
  2. Disable forced AA from the nVidia control panel or ATI's Catalyst Control Panel.

Screen Resolutions

Instead of making available all resolutions to all users, Prototype devs have decided to enable certain resolutions only for video cards with high memory. Only the following screen resolutions are available if your video card has less than 512MB of video memory.
•640 x 480
•800 x 480
•800 x 600
•1024 x 768
•1152 x 720
•1152 x 864
•1280 x 720
•1280 x 800

The following resolutions (plus all of the above) are available for video cards with 512MB or more video memory.

Performance Issues

Usually, random crashes and slowdowns are pretty hard to troubleshoot. But if you use a NVIDIA video card, try playing the game with v186.08 beta drivers (download). Also note that prototype might display the frame rate incorrectly (the game says your FPS is 10-12 while the actual gameplay is smooth). If this is the case, just ignore it.

  1. Update DirectX – If you are using Windows XP, please update to the latest DirectX monthly runtime. This will get rid of all the ‘missing dll file’ errors and will reduce the possibility of in game crashes. Latest monthly runtime can be found here.
  2. Update sound card and motherboard drivers - Click Here to download 3DP Chip for Windows Vista/XP – This program will automatically detect your hardware (video card, sound card and motherboard) and find available driver updates.
  3. Update Video card drivers – Both NVIDIA and ATI have recent video drivers out – you should always try updating to the latest official driver version available for your hardware for best performance. If anything goes wrong, the option to rollback to previous release is always there.
