SLI, its performance was very sluggish, and there were a number of

been much to report on as the experience has been very foul.
However, things have changed recently and with the recent NVIDIA
100.14.19 display driver release using GeForce 8 hardware — we
finally have some modest numbers to report on in a Linux SLI
configuration. Linux SLI is still far from perfect, but in this
article we’ve used two GeForce 8600GT graphics cards in an SLI
configuration under both Linux and Windows to compare the single
and dual GPU performance under both operating systems…”
