F.E.A.R 2: Project Origin

Strange as it might seem, the advantage GeForce GTS 250 1GB demonstrated over a 512MB version decreases as the resolution grows, although theoretically, it should be the other way around. However, further increase in the amount of onboard graphics memory has no real effect anymore. Only in 1680x1050 we see a slight performance increase that doesn’t even reach 4%.

Left 4 Dead

This game is based on Source engine and has built-in benchmarking tools that report no minimal performance readings.

We didn’t expect Source based game to set any serious requirements to the memory subsystem and it is actually correct: 512MB is more than enough for Left 4 Dead. However, overclocking helped Gainward GTS 250 2048MB to compete successfully against GeForce GTX 260 Core 216 – a solution from a higher segment.

S.T.A.L.K.E.R.: Clear Sky

To achieve playable speed in this game we disabled FSAA and such resource-consuming options as Sun rays, Wet surfaces and Volumetric Smoke. We used the Enhanced full dynamic lighting (DX10) mode and additionally enabled the DirectX 10.1 mode for the ATI cards.

Our expectations didn’t come true here, but the reason was most likely connected with not very aggressive detail level settings. Just like in the previous case, GeForce GTS 250 doesn’t benefit from having 2GB of video memory onboard. However, overclocking raises the card’s performance almost to the level of GeForce GTX 260 Core 216, at least in resolutions up to 1920x1200.
