1920x1200 High - No Tessellation
We believe Tessellation is disabled when set to "low," but regardless, when using that setting, the GeForce GTX 200 series performs drastically better. By using low Tessellation, the GeForce GTX 285 rendered an extra 93% frames per second while the GeForce GTX 260 received a 100% performance bump. The Radeon HD 4850 was also 82% faster and the Radeon HD 4890 achieved 58% more performance.
DX11 graphics cards received small gains, too. The Radeon HD 5670 witnessed a 29% increase while the Radeon HD 5870 became 11% quicker. Changing the Tessellation quality did little to improve the GeForce GTX 400 series graphics cards. The GTX 460 for example gained just 5% more performance.
