LAFENATU

I'm running it on a XFX R9 290 (on a AMD 8530 CPU though), heres a video if you'd like to see it running Ultra while recording using nasty Fraps and ENB Cry3.  Without recording I hover around 53 frames.
 
Get a SSD as stated above.  It really does help to put your OS and higher end games on there.
 

What all mods do you have installed? As said before, chances are it isn't ELS that is causing your game to crash or whatever your issue is because ELS is a fairly minor mod in terms of usage. The more mods you have, the more likely you are to crash. 

I think that it can run on any PC, until you have integrated Intel 1000 graphics with no dedicated graphics which my laptop had.
 
I can run GTA IV with 65+ Fps with this config:
Intel Core i5 4440 
ASUS GeForce GTX 750 TI
8GB RAM
1TB Hard Drive
 
I run with many scripts and car mods. I can tell which ones if you want so.

Hi guys!

I am new to the forum and have always looked for a video game to play as a police officer and came across this. It seems like there is a good amount of DL's and options for this.

Any advice or recommendations that people have? Must haves etc.?

Thanks in advance!
