Decided to revisit a classic from my childhood - Sonic Heroes 2003-2004. It runs decently on my onboard graphics Intel HD 5500, but there are times where the FPS drops and these occasions are quite often.
I have tried numerous times to force Nvidia graphics but to no avail. I have tried to run the game in win7 or win XP compatibility mode. Even disabled the Intel graphics processor but that only led to the game using Microsoft Default Display Driver or whatever.
I read somewhere that newer Nvidia graphics cards have compatibility issues with games that run Direct X 9.0 or lower, but im not sure how to debug this.
Does anyone have any idea how to get Nvidia GTX 940 M to run instead of the onboard graphics for Sonic Heroes?
