Black Ops (PC) worked great for me from release up until the 12/14 patch. Then, when the 12/14 patch came out, I started experiencing the lag spikes and stuttering so many people were complaining about. So, I decided to buy it for PS3. It lagged so terribly on the PS3 that i barely played 45 min on BO PS3! So, I went back to the PC version and spent SO MUCH time tweaking the config files, un/re-installing drivers, etc.
Treyarch should learn from a REAL gaming studio like Guerilla Games. Killzone 3 is due to come out in less than 3 weeks. So, what does GG do? They release a BETA because they KNOW THERE ARE CONNECTION ISSUES! I bet any money by 2/22/11 (KZ3 Release Date) that all these connection bugs and issues will be worked out!
SHAME ON YOU TREYARCH!
