Google Chrome: disabling PPAPI flash

After updating to the 21st version, Google Chrome by default uses a PPAPI version of the Flash plug-in, which is clearly not perfect yet and may cause some unwanted side effects:

• hardware acceleration problems (low FPS, low quality of graphics in the game)
• control problems (delayed response of the tank)
• disconnections due to "inactivity"
• random crashes of the plug-in

Solution

In the address bar, type about:plugins (or chrome://plugins), press Enter:

Expand the view (click "Details" in the top right corner):

Disable the PPAPI version of the Flash plug-in (do not touch anything else), then restart the browser:

Note: Chrome enables this plug-in after each update, so check the settings before playing the game.
