This might help someone someday.

Rockstar either have given up with PC customers and no longer care or put a complete idiot in charge of producing the PC version, who put a complete idiot in charge of the QA team OR just didn't bother with QA (which it feels like).

As a result there is a not insignificant number of customers (Rockstar claims < 1% haha) experiencing major issues with the initial release. I was one of those customers.

So my current opinion of Rockstar has violently degraded to 'you make great games but you suck and fail at releases and PR'

So, without further ranting, here are some links/info that should help out if your unlucky enough to buy and play it before they patch the problems:

General Info:
The initial release is full of issues including serious memory leaks and performance slow downs, I have 2GB RAM in my current rig and once the RAM usage gets above 89% the game shudders to a halt and FPS = 1. Some people say you can ALT+TAB, clear the RAM with a tool or such and carry on but that didn't work for me.

I installed the AMD dual core optimiser and AMD Fusion mentioned below and this seemed to mitigate the stability issues.

Seems any GTA4 patch will have to WHQL certified (lol so why isn't the game?), so that will likely delay the first few patchs.

You can read about just how important CPU is for GTA4... read 'terrible release code'. GTA4 PC CPU benchmark review with 13 processors @ PCGH

Resolution doesn't seem to matter atm, 1240x or 2560x has very similar crappy performance.
Getting the game running if your having issues:
  1. How To Get GTAIV Running @ Steam forum
  2. NVIDIA 79XX Users must get new drivers >= 180.84 @ Steam forum
  3. Fix for GFWL Login Issues @ Steam forum
  4. Missing Textures Issue @ Steam forum
You can always browse/search the Steam GTA forum or GTAForums GTA4 forum too for more specific help.

Kyle's Performance Tips:
Download, install, run:I forgot to mention: Pressing the 'P' key in-game toggles the post rendering effects, should anyone want to play around with that.

IMHO 180.86 drivers suck donkey balls, don't install em unless you have problems with a 79XX series card.
  • get the latest WHQL drivers (see point 2 if your running a 79XX card) I'm using 180.48 WHQL
  • disable all AA & AF settings
  • disable vsync
  • set quality to high performance
If you log into your Rockstar Games Social Club (RGSC) account, close the RGSC and setup a shortcut:

"E:GamesSteamsteamappscommongrand theft auto ivGTAIVLaunchGTAIV.exe" -nomemrestrict -norestrictions -novblank -percentvidmem 98 -framelimit 0
Just replace the path, with the path to your install. I feel this gives notable FPS increase and overall smoothness/responsiveness appears to improve. I might be wrong in thinking that I saw a large range of framerates... but it feels better.

With these command line options you can also set the GFX settings to whatever you like, regardless of your hardware.

Kyle's setup:
Since my main rig is offline:
Windows XP 32bit
AMD Dual Core Opteron 180

I have smooth, yet slow gameplay at 2560x1600. I'll post my in-game graphic settings at some point.

FPS floats between 15 and 30.

List of current command line options:
