There are several features, only turn one off at a time. You can turn them off at the driver, or turn them off at the TCP/IP stack (which is what the netsh chimney commands do)

The feature in question is the "TOE" or "TCP Offload Engine" and LSO which is what "Large Send OffLoad" and "Large Receive Offload" are. Different network chips implementations are completely different. Some chips may have these as one and the same. LRO is implemented by the network driver, so if it's flaking out for just people with certain realtek chips with certain driver versions, there's the blame.

Basically changing the setting with the device manager means it is disabled at the driver(hardware) level and affects all applications. TOE and LRO are of most benefit to heavy network use (eg if you have a gigabit connection to your ISP, and can pull 125MB/sec, it saves 1Ghz of CPU time. FFXIV uses barely more than 10KB/sec so it doesn't benefit by having it on or off. Where you benefit most from this is if you have multiple computers in the same network (eg streaming a movie off the hard drive of a file server) or devices like the Apple Time Capsule.
