I am not sure this is a support question but rather a general question so I will post it here and see what we see. Is the high number of app crashes an LCPDFR thing or a GTA thing? I have not seen many at all just in GTA but it seams when I start LCPDFR they are every 10-15 minutes or so. If it is an LCPDFR thing is this something that will be improved with the coming update? 

Gta 4 is very buggy when you have mods installed so its normal.

I've personally had GTA IV crash several times without any mods, although rare.  Once you mod it, though, stability is almost nonexistent.  GTA IV is very poorly coded for PC (can't speak for consoles).

 

GTA IV + LCPDFR uses more memory than GTA IV alone, obviously, and that is where most of the problems come in.  Also, most people add in modded cars to supplement their LCPDFR gameplay and that makes things even worse, mostly because of memory issues again.

 

A good resource for dissecting the crashing issues is devblog.lcpdfr.com which has a few articles about GTA crashes (mostly memory related).
