NFS Trial/Deluxe Edition and some issues....

Ok, this is probably a stupid question, but my trial of nfs is over now, I played the 10 hrs. Should the "trial" version be uninstalled or will the full game release overwrite the trial files? 

Ok, now for the issues in the game. First off, the game is great, looks good, the handling is great, excellent graphics, etc. There seems to be a problem with steering sometimes however. You go to turn and your car goes straight. Into a wall, a tree, a curb, etc. Not sure what could cause it. 

Like a few other unnamed NFS titles, MICRO-STUTTER!!!! Why is it that almost every damn NFS title that GHOST games or Criterion make, it has micro-stutter in it? Or some glitches/bugs that cause fps loss, static in music, etc like in Rivals. Apparently, someone at these companies knows nothing about game optimization for PC. 

When I first installed the trial version, there was stutter, etc. Played for a bit, logged off. Got on today, game played fine. Few hours of playing, logged off for a bit. Logged back on, more micro-stutter. GTA V, Skyrim, Mad Max, all my other games play fine. Rivals for me plays fine, but my old computer it was hell even playing it. My new build, which I'm on, built not even 2 1/2 months ago, runs GTAV, etc, 40-60 or more fps. No stutter, lag, etc.Yet, here we are with a new NFS title, and again comes with it, micro-stutter, etc. I know it's not my rig.

So, i know it's not my system or my internet. Internet is through my cable company. High speed lightning turbo internet. It has to be something in the server/s or the games files. 

Other than that, the game is really good. Just needs to be tweaked a little more to the difficult side. The races, etc are just too easy to beat. In the 10 hours I played the trial, I'm almost lvl 40. Have almost 100k, after spending no telling how much on part upgrades and stuff already. I got the fox body mustang for the storyline starter car, and the tricked out starter bmw from the deluxe edition. My Mustang is almost fully upgraded already. I haven't even started on the bmw yet. The game really needs the difficulty raised. A LOT. 

Well, that's my two cents and concerns on the game so far. Might have more as I play the full version when it's released. 

oh yes, there is two other quick things, DAYTIME and COMPASS!!! There needs to be a daylight cycle in the game, too dark in some spots. Transition from tunnel light to night darkness causes a few second vision hinderance. And WHY is there no compass around the mini map? Majority of people in the world, like to know what direction they're going in....Compass. Needs to be on the mini map while you're driving. 

Ok, that's enough from me. I'll be playing Rivals until the full release is out in a few days. Late.
