Because I am pretty sure that some guy at rockstar hired his retarded nephew to port this game all by himself.
 
Having just booted this game up and played around with it for a while after I bought it at the xmas sale I have some issues with it.
 
1. You know you are in for something truly special when you have to spend 15 minutes reconfiguring keys so they make some sort of sense (left alt to attack seriously?)
 2. It runs like shit, my PC rig is far far faaaaaar beyond the recommended requirements but it still slows down to like single digit FPS at times.
3. After a race my hand feels like it's going to explode why in the flying fuck do I need to tap the run button to go at a decent speed again?
4. It crashed 2 times in the 5 hours I played around with it.
 
Now Rockstars PC ports are often mediocre at best, mostly awful (cough GTA 4 cough) but atleast they somewhat worked, whatever you do, do NOT buy this game on PC not worth it even the 2 dollars I spent on it feels like a ripoff at this point.

One hundred percent agreement. Bully is one of my favorite games of all time, but the PC port is an atrocity.

Sorry my bad. I made it. I'll do better next time I promise.

I plugged in a 360 controller and felt it was fine =(

Vicious.

I had the two gigs of ram problem and the latest patch fixed. After that, it wasn't exceedingly great in the performance area but it was okay and didn't crash on me after that. 
  
I preferred using the 360 controller except in a couple parts where you had to snipe people at which point I switched to the mouse.  

Bully is definitely my favorite Rockstar Game of all time as I've owned it on PS2, 360 and PC. The first 360 game I ever S-Ranked.

Sounds like the fuckers behind the GTA IV port. I can play Crysis at Max settings, but GTA IV runs slower at the lowest possible settings.

Rockstar never had a great port of their games to the PC.  cept maybe San Andreas which i haven't heard too many problems with.

Saints Row 2 PC port would have to give it a run for it's money. That thing is mindblowing...

Saints Row 2 is an awful port....
 
Bully works fine as long as you have 2GB of RAM and either leave Vsync on or turn it off...I forget. One of those is correct.
 
Also use an xbox controller.

In what way?  The port is fine, the problem was that they recommended specs far too low on the box, below those of the 360.  With a half decent dual core CPU (e6750) and 9600GT I was able to fully complete the game in highest detail sans FSAA.   Played it all the through in co-op with a buddy too.

Played the PC port a few months ago to completion. Seemed pretty fine to me, except for maybe the washed out textures.

You should definitely play this on the 360. I never had any of the crashing issues, it doesn't have the CRAZY load times the PS2 version had, and it's graphically better than the Wii version.

Played it with a 360 controler, made it much better.
Also ran fine and not a single crash, but hey that's PC gaming, experience will vary from rig to rig.

Bully was an awful port, but to be fair it looks far better than the console version.
