Okay I bought a Lenovo gaming laptop in order to test this.
And the above comment is correct!
- The tag "--force_high_performance_gpu" allows my game to use the nvidia GPU! It runs wonderfully smooth.
- But if I also have the "export for steam" button checked, it will NOT use the nvidia GPU, and instead the weak one, and does not run as well.
Ashley should we now update the NWJS "Export for Steam" option's "--in-process-gpu" with the new one: "--force_high_performance_gpu"? I'm not sure what the old tag did, but since it's blocking laptop's GPU's from being used maybe it should be changed so the games run better for more of our Steam players.
