Anyone else get long (4-5 minue) loading times or infinte loading screen?

I'm sat here with IV in windowed mode just loading and loading and loading for 2 minutes, any definitive ways to speed it up?

Are you running the game as administrator? Are you using many mods? 

Running LaunchGTAIV as admin yeah and list of mods?

LCPDFR
SNT

That's it but even on a vanilla mod-free install it takes just as long to load in from the main menu.

Sidenote: I like the loading screen theme but it gets old when I'm hearing it after EVERY crash. So any way to silence it or lower the volume or no?

What are your computer specs, sounds like your PC is struggling to keep up. 

Specs?

Okay here you go:

 

Processor: Athlon II X64 640 3Ghz Graphics: GTX 480 RAM: 8GB, OS: Win7 64bit

I can run other demanding games (Crysis 2-3, Ghosts) maxed out though whereas IV seems to under report what I got but I do notice IV leaking memory like crazy. It may not be my system though as I've had the slow loading issue on a number of machines, desktop, lower spec laptop, higher spec older PC

Any command lines I can use to maybe speed it up?

Also I have the LAA flag set but how can I tell IV to use 6 outof my 8 gig of RAM?

Try and disable clip capture and use this commandline: 

-novblank -norestrictions -percentvidmem 100 -novsync -frameLimit 0 -nomemrestrict

Gonna give that a go, thanks.

Does it matter that I run it in a window since if I run it full screen it absolutely loves to BSOD on me though?

Running in Windowed mode seem to help for some users, so if you want to do that I see no problems with it.
