We tried both of us enabling it and both of us disabling it and still no luck a few areas i am still not clear on is the effect of Vsync.We tested 3 options for playing and the result is the same 1) private match 2) LAN via Radmin and P2PLauncher and 3) we both click matchmaking at the same time and let ubisoft join us.We both tested this on original copies of the game, been playing for almost a decade now so I guess a version being out of match is something I would have picked up :).Me and my friend have completely disabled the firewall, would it still need an exception? if yes I might have to check.Ubi has the choice of either spending tons of time bolting on even more junk onto their overstuffed 15 year old engine or dropping all of that and rebuilding entirely from the ground up on the latest Unreal tech. This is why you haven't seen a Splinter Cell in almost a decade. Why? Not because PC can't handle it, but because the engine under Windows can't recognise more than 1 input device at a time and Ubi couldn't be assed coding a handler. Things like splitscreen is actually still very much there in the game, just turned off. Ubisoft has continually bolted on new, custom stuff to keep it going for Splinter Cell right up to Blacklist in 2013 and it's a complete mess (breaking into Blacklist UMDs shows so much old data from previous games as far back as Chaos Theory). Sadly, all Splinter Cell games use the same engine - Unreal 2.5 and every other game company abandoned that engine back in 2006. If this is the case, then that would go a long way to explain why some games work fine with some people and others desync as 1.0 players can play with 1.0 and 1.04 with the same, but never together. If one party is using a legit copy which would be 1.04 and another is using a "liberated" version, they may well still be on 1.0 and they'll need to be brought up to 1.04. Lastly, are any of you using, shall we say "liberated" copies of the game? Reason I ask is because there is a possibility of a version mismatch causing the desync. How are you actually playing it online? Via Ubi servers or are you hosting private LAN games either through a WAN / LAN setup or via something like Tunnigle? Do desyncs happen regardless of who is hosting? This will help establish if one party actually needs to mess with their router or not. If both parties are already set up correctly firewall wise, take it a step further and test that the issue occurs for both you and your friend by each being the host and having the other join. First and foremost, check the most simple thing is done on both sides, so check yours / friends windows firewall exceptions and make sure there is an entry for conviction_game.exe or Tom Clancy's Splinter Cell Conviction and both sides have Private ticked.
