So..here is the question. If you're designing a NIC for the lowest latency possible..why would you not offer Winsock Direct drivers, or SNP capable drivers?

WSD is used extensively where low latency is critical. Sub 6ms is very common, vs the 15-20 for a decent GigE card.

Features like TOE, RDMA, etc are also nice, but probably not as useful for gamers...

Just asking, because the STANDARD broadcom 5708 ASIC now appearing on new system boards has ALL of these features available....

Lots and Lots of reasons.

Winsock direct is not for client computers.

Winsock direct does not use UDP/IP (which is the protocol of choice for most games today).

Winsock direct is not optimized for gaming.

Winsock direct is not focused on latency, but rather cpu utilization for high-throughput applications (which gaming is not).

I could go on

Believe me, I helped define the specs. for a lot of the technology inside Winsock direct and other similar technologies both at MS and in the IEEE...

and nothing like what LLR (Killernic.com) does has ever been done before for online games.

Thanks for asking the question though, it absolutely highlights the differences between Bigfoot's technology direction, and the rest of the boring corporate server world.
