Currently this only works with the 2D APIs. making sure you are using the software rendering and not 3D rendering, if the game supports it. Some older games require admin rights to function properly. running the game with administrator rights.This option tries to fix several common exceptions, such as the divide by zero exception in old games that were trying to calculate the CPU speed.
