I installed GTA IV on my desktop and it runs fine, getting bout 60~70 FPS on maximum settings. I also installed it on my Laptop and had gotten FPS ranging from 50~60 and at times, 90~110 on indoor cutscenes. What really got on my nerves is that though I can play GTA IV on my laptop just fine with decent FPS, smooth gameplay but it suffers from lag spikes every few seconds. Anyone could enlighten me on why does this happen? If it weren't for the spikes, I'm able to get 50~60 FPS with extremely smooth gameplay. It's just the spikes. I had also done some searching around the Support Section of the forum and found certain tips and tweaks but these are just for low-end computers and nothing to do with spikes no?

Sound & Graphic Drivers are up-to-date. On a side note, I heard that there's a way to allocate available page file into RAM?

Can i get your Laptop? FPS 50 -60 is the bomb.

I had to manually kill applications in the service tab and application tab of Task Manager.  In the service tab try ending the following:  Diagnostic Service Host, Windows Font Cache Service, Diagnostic Policy Service, Windows Media Player Network Sharing Service, Windows Live-ID Sign In Service, Print Spooler....just to name a few.  There are a slew of other program services I shut-off in msconfig as well, so many of the unnecessary services don't even start up.

 

Anyhow, that helped add FPS and stability to my LCPDFR setup.

 

Good luck,

Update:

I tweaked my NVIDIA Control Panel settings as I had done some researching. It seems that GTA IV is badly optimized and I had to turn off "Anti-Aliasing" manually from the panel, manually select the PhysX Processor. I had also did a small fix by re-installing my Graphic Drivers via "Driver Fusion" and am I glad to say, the spikes seem to had decreased dramatically and also running on High Settings including ENSB's AA mod. Spikes still exists but not as much as before. Playable but still not satisfied.

Thanks for the info! I had just did that but that still doesn't eliminate the spikes.

You should probably get some sort of recording software that'll record CPU and GPU usage, as well as running services and processes, then check out what's running and screwing you over when the spike hits. But sheet man, my laptop can manage like 25 FPS on low settings ;[

 

Also, a bit confused on how you have 2Gb of RAM... Shouldn't that computer come with 16Gb?
