My experience comes from a racing service that breaks up bad when you have bad latency. You would be ghosting all around just like you see on DCS. this using a Cisco usb Wifi-N card. So I decided to get it hardwired to my pc from the modem, BAM! Even with a high ping lets say 270ms (to an Aussie server)I had 0 ghosting.
People i've recomended giving it a try had very positive feedback on their game experience.
Almost forgot! There is also this weird coincidence between the server messages(farps status, bomber cal message etc...) being distributed, causing microfreeze episodes. Could this messages be sent to the webapp instead them being ingame?.
