How do you enable the flash plugin in your app?
In order to help you I would need to see your GlobalCEFApp initialization code from your DPR file.

Do you use this code ?
Code: Select all
GlobalCEFApp.FlashEnabled := False;
GlobalCEFApp.AddCustomCommandLine('--ppapi-flash-path', ExtractFilePath(Application.ExeName) + 'plugins\pepflashplayer32_28_0_0_161.dll');
GlobalCEFApp.AddCustomCommandLine('--ppapi-flash-version', '28.0.0.161');
If you use that code you can improve Flash performance adding this :
Code: Select all
GlobalCEFApp.AddCustomCommandLine('--enable-accelerated-plugins');
GlobalCEFApp.AddCustomCommandLine('--enable-gpu-plugin');
Remember that you can also use this instead of all that code :
Code: Select all
GlobalCEFApp.EnableGPU := True;
GlobalCEFApp.CustomFlashPath := 'plugins';
It's also recommended that you set a cache directory :
Code: Select all
GlobalCEFApp.cache := 'cache'; // this directory must be writable

The first screenshot shows the parameters of a web browser using the flash plugin installed in the system with GPU acceleration enabled and a cache directory.
That configuration should give the best performance!
Please, test your game with the official CEF sample application :
http://opensource.spotify.com/cefbuilds ... nt.tar.bz2
Decompress that file, run cefclient.exe with these parameters and test your game :
Code: Select all
cefclient.exe --enable-system-flash --enable-accelerated-plugins --enable-gpu-plugin --cache-path="cache"
If you still see the same problem, please post the URL of your game if possible.

If that flash game also has problems with
cefclient then these could be the causes :
- An unknown CEF3 bug.
- An unknown Flash plugin bug.
- An unknown bug in the GlobalCEFApp.SitePerProcess feature. Try setting GlobalCEFApp.SitePerProcess to FALSE.
- That game may be included in a web page with ads that are blocked in Chrome but cefclient shows everything. Those ads may be the cause of the high cpu usage.
