Performance in Third-Person 3D Shooters
Just Cause 2
This game’s integrated benchmark does not report the bottom frame rate, so we use Fraps to get such data.
Like in the previous test, the GeForce GTS 450 SLI stumbles at the resolution of 1920x1080 where it cannot deliver a playable bottom speed, being inferior to the GeForce GTX 470 as well as to the less advanced GeForce GTX 460 1GB. So, using the two entry-level Fermi-based cards in SLI mode makes but little sense here.
Lost Planet 2
Here is another common problem of homogeneous multi-GPU solutions: they depend too heavily on driver support. We couldn’t even launch Lost Planet 2 on our GeForce GTS 450 SLI tandem because the game would crash inevitably. We can only note that the ASUS ENGTS 450 TOP is much faster than the reference card.
Performance in RPGs
Mass Effect 2
We enforced full-screen antialiasing using the method described in our special Mass Effect 2 review.
It’s the first time we see our GeForce GTS 450 SLI tandem enjoy a large lead over the GeForce GTX 470, but it also falls behind the latter at 2560x1600, its bottom speed plummeting below a playable limit. Thus, the more advanced single-processor card proves to be a better choice again.
