fellow gta4 pc. cannot pass the last mission either. Im running on a p4 3.2ht with 1g ati radeon 2600agp and 3g ram.have tried cut graphics settings, turning off all unneeded services in win 7 32bit, and even turning off antivirus and firewall in mcaffee thru task mgr to twerk the performance of the machine. Im working on a developer machine so Im runnning vs2008pro and sql2008 enterprise along with office enterprise and expression web. after cutting startup services i can get my processes down to 49 on task mgr. gameplay is fluid on lowest graphics setting and choppy on the highest graphic settings, so ive been playing on lowest settings on a clean win 7 install since sept 9,09. came to the decision, and played thru both options no cheats on any saved games in quest for the lost and the dammed. Still I cant get on the helicopter on the last mission. The boat is always not where its supposed to be no matter how prepaired i am. I cant even get under the carrot for the last mission. Its like the character niko takes to long to get on the boat after being dropped from the helicopter, and then the character niko wont sit down after you do get on the boat. Its oct 16 and ive been on this mission since sept 29. game wont let me progress. help please if you have any suggestions. thanks kevin. gvin@live.com
