With the DarkPlaces-powered Nexuiz game, when running at 2560 x 1600 with HDR, the Radeon HD 5750 was noticeably slower than the Radeon HD 4800 series graphics cards (but faster than the Radeon HD 4670/4770), while the Radeon HD 5770 managed to pull ahead of the RV770 graphics cards. In this test, the Radeon HD 5770 was just under 10% faster than the Radeon HD 4870.
