I think it's widely known that PD's GT5 servers have been below par since day one. This has been particularly evident in recent weeks with complaints about connection problems and severe lag springing up all over the net. Other than raising the maximum number of simultaneous connections (ie, the number of players that can play online worldwide at any one time), PD seem to have done almost nothing to resolve these issues. I find this very odd given that GT5's limited singleplayer features mean that online play is essentially the be all and end all of the entire game, particularly for those that have owned it for more than a couple of months. Anyway, to the point. There may not be anything we can do to fix their servers, but there are a number of 'solutions' out there to help reduce or eliminate any problems on our end. This thread is for storing those solutions in one easy to find thread so that those experiencing issues with RD events can give them a try. If you have any information on potentially improving online connectivity and performance, please post it here and I will add it to the main list. Also feel free to ask questions about any of the solutions listed.
