D3DRightMark is an independent non-commercial open-source graphics card benchmarking project developed by iXBT.com. It's designed to help users estimate graphics cards performance and quality in synthetic tests and real apps, e.g. games. Synthetic tests allow estimating performance and capabilities of separate graphics cards subsystems in order to forecast their behavior in either applications, both existing (that is overall estimation of suitability and prospects for an entire application range) and developing, provided that a given accelerator demonstrates peculiar behavior under such applications.
D3D RightMark enables you to know:
