GeForce GTX 260M Game Requirement Analysis
GeForce GTX 260M is a high-end-class level GPU of the 200M Series released by NVIDIA in 2009/2010.
The biggest hindrance it has is the fact that it only supports DirectX up to 10 so DirectX 11 games aren't supported.
It's based on the architecture 'G92b', same used on the middle-class GeForce GTS 250 part of the desktop 200 Series. The performance should be much lower than the desktop GTS 250, due to the lower clock frequencies and less amount of Pipelines but higher than the GeForce GTS 260M as it features extra Pipelines and a 256 bits Memory Bus, as well as higher clock frequencies.
Compared to powerful Mobile GPUS (e.g. GTX 485M, Radeon HD 6990M), GeForce GTX 260M is not far behind and it's capable of playing demanding games (like Crysis 2) at high settings. However, very demanding games like Metro 2033 can only be played at low or medium settings, depending on the resolution + DirectX used.
