I have seen threads in this forum that discusses the LAN gameplay in GT4, but so far I haven't found any that are specific to issues and details during actual gameplay. I used to get together with my friends every week for GT3 i-link races with 4 to 5 people, and now we have started playing GT4 through LAN. So far here are the facts of our last setup : - All using GT4 Asian version (Chinese, with English car names) - 2 PS2s with network adapters, and 1 PSTwo (built-in network adapter) - Linksys WRT54G broadband router as the hub We all had about 30% of the game completed in each, but all tracks are open if we were to be looking at the 1 player Arcade mode track selection screen. My main complaint : HOWEVER, once we were in LAN mode, there is only a limited selection of tracks (about 6 or 7 if I remember correctly). The mixed tracks were not even grouped (as in the 1 player arcade mode screen; into open circuit, city tracks, & so on). Anybody know why this is so? The only thing I can think of is that our games were only 30% completed, BUT I doubt it, coz I tried playing 2 player split screen and ALL the tracks are available! Anyone here completed 100% and tried LAN play? Another annoying thing is that they limit the car selection to about 30 cars (prioritizing the ones we selected as our favorites). Lastly, once we are in LAN mode (connected), there is no way back into the main menu without rebooting your PS2s! So, if we want to change those 30 cars from our LAN favorites, we all have to reboot, change the favorite selection, save, and then connect again, which takes so much time. Other technical issues : I have tested the LAN settings over and over and found that these settings below result in the least lag (YES, I said LAG! Coz the game stutters! Then again, it may be my router settings, but it doubt it coz I play other games + other consoles using the same network hardware). These are the best settings : (stutter almost unnoticable) Host network load : normal (the low one) PS2 network adapter setting : 10baseT Full Duplex If we use the 100baseT full duplex, we don't connect at all. If the host uses the LARGE network load setting, the game stutters so bad that it becomes unplayable. If anyone out there has any comments, advice, or input please do help. Thank you.
