Performance in Simulators
Race Driver: GRID
Just like in most other tests, twice as much video memory doesn’t give Gainward solution any real advantage over the competitors. However, overclocking helps it to significantly outperform Radeon HD 4850 and get close to GeForce GTX 260 Core 216.

We used the in-game benchmarking tools that do not allow measuring the minimal frame rate. We also enabled DirectX 10.1 support for ATI’s solutions.
This flight simulator is pretty sensitive to the amount of video memory, but you can only feel it in 1920x1200 resolution where GeForce GTS 250 solutions are no longer fast enough to ensure acceptable gaming comfort. In lower resolutions there is no difference between models with 512MB, 1024MB or 2048MB of memory onboard. Overclocking doesn’t seem to help GeForce GTS 250, either.
