Mouse/Keyboard Lag Unbearable

[Major_A]

I can hardly play this game at certain times. Sometimes it can take up to 5 seconds for the game to recoginze that I let off the gas or turned. I find myself ending up in the trees way too often. I just finished the mission where I needed to blow up the containers and hijack the "coca" truck and take it back for the boss. I was having such a hard time trying to keep the truck on the road it took 10 tries. I was hoping it was the game lagging but the police/milita were still raming me and firing while I was having issues.
Other times I can be running along and go to shoot someone and the same thing happens. It lags when I stop running, start running, go to shoot, or aim the weapon. The most frustrating thing is this happens 60% of the time. If it were 100% I could chalk it up to another issue or wait for a patch.

If this game doesn't have good support I could see it taking that same road as another game that seemed good but was unplayable due to bugs.

I played that game a total of 5 times. I waited forever for a patch, installed the patch, did nothing for me and I uninstalled. Sold the game on ebay for $10 and moved on.
