Geoff Gasior writes: In the early days of GPUs, application-specification performance optimizations in graphics drivers were viewed by many as cheating. Accusations were hurled with regularity, and in some cases, there was real cheating going on. Some optimizations surreptitiously degraded image quality in order to boost performance, which obviously isn't kosher. Optimizations that don't affect an application's image quality are harder to condemn, though, especially if you're talking about games. If a driver can offer users smoother gameplay without any ill effects, why shouldn't it be allowed?
