ACC keep crashing all the time now

[Isaac Chavira]

THIS ISSSUE HAS SINCE BEEN RESOLVED BY THE MANY UPDATES FROM KUNOS.​

Hello,
did you check the game files via steam:
check your video settings
delete the ACC folder in my documents after making a backup of your settings.
re-check the cache after deleting the ACC folder in my documents.

Otherwise the nvidia 445.75 drivers will cause the unreal engine to crash.
a hotfix was published 445.78.

NVIDIA GeForce Hotfix 445.78 - VideoCardz.com

GeForce Hotfix display driver version 445.78 is based on our latest Game Ready Driver 445.75. This Hotfix driver addresses the following: Some DirectX 11 games may fail to launch when Image Sharpening is enabled from the NVIDIA Control Panel

Okay I will try that, thank you

 

[Isaac Chavira]

Nope, still crashing

Can you give more details about how and when it crashes? Does it crash as soon as you load ACC? During a race? Does it crash to the desktop or does it crash your whole PC? Have you updated your graphics driver recently? Do you get any on-screen messages? Does it show up in your windows crash log?

 

[Isaac Chavira]

It crashes during races, practices and qualifying. Yesterday I made it all the way through Brands Hatch from Q1 to R2. But then at Misano, FP1 crash to desktop. And that is every time it crashes (desktop).

Disable Image Sharpening in Nvidia Control panel

 

[Isaac Chavira]

Will do

It already was off.

Have you overclocked your GPU/CPU? I've notice overclocking my GPU crashes the game all the time.

Indeed, UE4 does not like GPUs to overclock too much, however if you do not push your overclocking too hard, there will be no problems.
In my case: EVGA RTX2070 ultra, stock_1410 Mhz/overclock 2075 Mhz, pass, but 2080 Mhz crash.
Mem: stock 1750 Mhz/OC 2000Mhz pass,but 2050 Mhz crash .
For exemple

It crashes to desktop immediately on launch for me ever since 1.5 dropped. I am not overclocking the CPU or GPU, only running Windows Defender, but i have added ACC to the the exclusions and the ACC folder in My Documents. If I uninstall ACC and then reinstall. I can then play, but the following day it crashes again.

same problem here, so it seems. Rx Vega 64, ryzen 3600x and CV1

 

[mr m bulsara]

I had the same issue, System AMD 3700x, my memory is manually tuned 3600 tight times and this was the cause. Fix dropped my clock to 3533 and its now stable.

 

[Michael Payne]

The problem went away for a few months, now it seems to be back. I have to validate the files before I can play and it keeps finding 2 invalid files and needs to download them again.

any developments? I re-installed ACC, I have everything stock and it continues to ctd (happened again today)

 

[Mosqu!to]

My ACC is also crashing constantly. It started first when getting to the track, it crashed instantly. Then i checked files and steam redownloaded 10GB.
Now i can play for 10-40 minutes and crashes randomly. I have also noticed Simhub and Fanalab crashing out... All system is on stock clocks.

All drivers are up-to-date.
I also have Win 10 20H2 installed last week. Is that causing this issue?

Antivirus applications can and do remove files I read on this or kunos forum somewhere that people were having ACC files removed so had to exclude the folder from AV scanning.

 

[Ho3n3r]

Anyone who keeps getting crashes and has fiddled with the UE engine.ini file, should delete it and verify game files so that you have a clean one. I've seen all sorts of issues on the Kunos forum being solved by that, and the devs have made a post indicating that it's not supported, which makes sense since they use their own modified UE version.

I am not running any AV, only Windows Defender. I have also added the Steam Library Folders and also specifically the ACC folders to the exclusions. It still seems to corrupt and I need to validate the files.
