All the images pretty much look the same. There are differences, but they're not really noticeable. 8xS has a slightly sharper image, again probably due to supersampling. Now, let's look at aliasing in motion.
Aliasing in motion
2xQ
8xS
SLI 8x
We can see that SLI 8x has slightly less aliasing in motion than 8xS. However, it's still not able to eliminate all of them. It's 2xQ that's very effective in this test. Unfortunately, there are no SLI 4x or SLI 4xQ - that would just be perfect for this game. Next, we have Star Wars: Knights of the Old Republic.
Now we're seeing the best example of what SLI 8x can do - quality wise. By far, SLI 8x offers the less aliased image than both 8xS or 4x. Look at the far room, you can see aliasing in 4x and 8xS that's not present or as noticeable in SLI 8x. Let's see how it looks in motion. These zip files are quite big (around 15 to 20 MB each), so they may take a while to download.
Aliasing in motion
4x
8xS
SLI 8x
Whoa! 8xS is pretty much the worst in motion, even compared to 4x. Furthermore, 8xS will not work with frame buffer effects on. Now look at SLI 8x - it's just so good you can hardly believe it. There's very little aliasing and it works with frame buffer effects. This does prove that SLI 8x can offer even better visuals than 4x or 8xS. What's even more good news, at least for those with GeForce 7 series, is that you'll be able to use SLI 8x with transparency antialiasing with supersampling to deal with transparent textures aliasing. We'll come back to this subject later, but for now, let's take a look at what two GeForce 7800GTX in an SLI setup has to offer in terms of performance.
