Since the gameconfig on this site is not working, and the most recently released gameconfig did nothing, I have stayed up for the past 24 hours straight perfecting a gameconfig.
I have a heavily modded currently updated steam version that sufferers the same crash to desktop everyone else is facing. I think I found out why. It's is a memory leak but not the normal kind.
I'm currently testing right now. I have addon cars installed and graphics mods. What would have crashed my game before is running great. I'm on hour 4 of causing constant chaos with no crashes. I will release a video and upload as soon as I'm sure I didn't just get lucky.
With my changes and research I have made I'm hoping this will become an open project so anyone can make changes to the gameconfig and not be limited by someone else. I will be showing fully the changes I made to get there. More testing needed.
One question is needed to be asked, and that is full system specs of a gta 5 that crashes. If your gta crashes after a period of time, PLEASE post your system specs.
