You guys are kidding with the "Feature" thing right?
In a game where you can instantly zoom in 3x with no optics(wish I could do that in real life) at any time, or jump out of a plane going 300mph toward the earth 20 feet before impact and parachute to safety, or fly into one tree and be fine one second and get shot by a handgun the next and get blown up like there was C4 strapped to the entire plane... You really think that they were going this far with the "inertia" thing?
Beyond that. I know that their "inertia" system works perfectly fine. If you get into a tank and try to turn the turret you will notice that it slows down your mouse sensitivity rather than delaying it like we are experiencing here. So our problem only compounds the aiming issues of big weapons.
This mouse acceleration problem has been in MANY games: Bioshock, Almost every game based off a movie for the past 3 years(Uhhhg Wanted: WEapons of fate was horrible), and Most games that were ported to PC from a console.
It seems like only some game companies take it seriously right off the at(COD4 for example). From what I've read about this kind of problem over the past what... 5 years? Is that it mainly has to do with performance mice such as laser mice or ones with High polling rates that require special drivers. Not to say some people don't have it with a random 10$ Microsoft mouse.
I think BI is probably working on this right now. I've gotten my lag to a tolerable level just based on the fixes in this post. Hopefully they will release a total fix in a patch sooner or later. It doesn't really matter though. The game is great no matter if there is a little delay in your mouse or not. Its not fast paced enough to require COD4, CS:S type accuracy.
