FCAT: A new tool for measuring GPU performance.

Overlord

I found this article that shows some interesting data that indicates multi-GPU setups aren't that advantageous. I'll let you make up your minds though:

Edit: BTW it's 10 pages long.

It's been known for a while that SLI like setups are pretty pointless and that a dev really needs to work on the code to make it viable.

You gain much higher performance gains if you simply make your game 64-bit compatible which in some cases is as simple as enabling a flag on your EXE.

It also doesn't help that nvidia hasn't (who started the trend) been pushing it much at this point, they did a couple of years ago, where on boxed copies you could see a sticker saying "SLI Compatible", but it quickly died out since there isn't much point to it.

Besides that, many gamers also aren't willing to put the cash for an extra card that all it really does it give back a % gain (15% in some 'highest' cases) as opposed to doubling it as you would assume by plain numbers (bottlenecks not withstanding).

I know, but it helps to see some hard data to support it. It's something to point to when some suggests going multi-GPU.

Beyond that, these benchmarks give some better insight than pure frame rate.
