Ever since AMD absorbed ATI it's been a completely different company, but the fact remains that OpenBVE was built to optimize its performance on the AMD processor, which was built for mostly gaming, rather than multimedia, like Intel. Besides, regardless of the graphics card or processor, the fact remains that OpenBVE draws all of its rendering capability directly from the GPU, whereas other simulators(and video games) are integrated to the system and utilize DirectX, and/or OpenGL, so it actually demands more than what you all think, but in the very weak areas where the system can't offer it. In order to improve capability and maximize development, this one hurdle must be overcome so that we expand the limits of our projects.
