Peterbilt 389: Optimus Prime + Review

This is a really nice truck, I have driven other Peterbilt 389,s but not like this one.
There is a fair amount of options with this truck, you get 1 cab, 4 chassis, 10 transmission type’s and a lot of engines. Plus you get the standard paint, the metallic paint and the Optimus Prime paint.
I did find, that when I opened the RAR file, there were 3 more RAR files in it. One was the truck, then the trailer and the 3rd one, I have no idea what it was. There is NO read me file with this truck, so as for the 3rd RAR file. I do not know what it is or what is it suppose to do
I also found that this truck is a frame rate hog. It will eat up your frame rate like it did to me. I had to turn off my Graphic’s mod to be able to drive this truck right, or to even have this game run right.

I will recommend this mod, but use caution, if any one out there knows what that 3rd file is to do, then please leave me a comment.

  1. i downloaded it no problem, but once i go into the game and go hookuo the trailer and drive the game starts stuttering and jerking and going very slow, it does not do that with my scania T, i dont have a great pc tho but it plays ok with me using mt scania,,, pith tho i like the peterbilt

  2. What I dont agree with, is that you say “this is the best mod till’ now!” Even though the creator of the mod wrote this.

  3. first great truck love the sounds the only problem i have is when i use the angle eye lights they don’t light up the road ahead like driving lights do

  4. I’ve got a game breaking bug with this truck, enabled all 3 mods in-game, but when I go into the dealer, the game just crashes to desktop as soon as the truck is seen. No other mods installed, and my pc can more than handle the game. Anyone got any ideas ?

  5. I think the mod author has mistakenly allowed this truck to appear in traffic. Might want to check this, as the textures and such are enormous and the game struggles to render them when this happens.

  6. The mod works for me, but the Optimus Prime paint scheme you buy from the repair shop doesn’t render right for me.. it’s all red with some bogus stretched text on it, but the funny thing is that the Tuning Optimus Fender renders fine, and inside the cab I still see the flames on the hood (externally they aren’t there).
