Firstly, this isn't a C&C:Online related problem...
I have tried Right clicking -> Run with GPU
Well this should be solution, but since it's not working for you...
Try to add manually RA3EP1_1.0.game (not RA3EP1.exe) in NVIDIA Control Panel (from the recently opened program list)
Some laptop may use automatically integrated graphics when using battery, so you may need to play with wires plugged in.
Thanks for the help, but no luck I'm afraid :(
Just got it running smoothly, I launched it from the 'Dragon Gaming Centre' App as last ditch attempt, added it to the 'instant play' menu and released all resources other than steam. Running very nicely now! I'm supprised that worked.
Thank you again for the help Viper.Go to the full post
