So... I've changed a shit ton of things around my game as of yesterday. It was working perfectly fine for abit then I don't know what I did, and now It just crashes for no reason then LCPDFR tool comes out and says it wasn't LCPDFR then tells me I can relaunch my game. Also whenever I launch the game, it does the exact thing as soon as I load it then I relaunch it and it's fine for alittle then it crashes like in the video I've just posted on youtube. 

If anyone could help... I'd greatly appreciate! Please help!?

Could you post the crash log? Please.

 

 

Could you post the crash log? Please.

 

How do I find that?

In the main GTAIV directory there is a file called 'LCPDFR.log' that is the log for LCPDFR.

This be the file I require, please.

Spoiler added. Please use a spoiler for logs in the future.

Looking at the log I personally can't see anything that is possible causing the crash. The only thing I can think of is that when you have mods installed in GTAIV is that it is really quite unstable and that maybe one of the things that you have changed recently has caused the game to crash more frequently. Try removing the things that you have added and reverting any setting changes that you have made and see if that helps. I'm sorry if I have been a complete waste of your time. I can usually spot these things pretty quickly.

lol I changed a ton of this... Ranging from scripts to cars, to handling.dat to cargol to all kinds of other things. I'm not sure what's different... I get decent FPS (Roughly 20-30ish. Then it just crashes out of no where.
