So, I've been having constant CTD and BSoD while playing Divinity Original Sin, pretty much since launch, and just yesterday I found the reason why.
First my specs:
Windows 7 Ultimate (64)
Intel Core i7-3770 CPU 3.40GHz
8GB RAM
Nvidia 9800 GT 1GB
I just formated my PC yesterday and installed the lastest drives. Normaly I only keep the GPU card's drive up to date, and update the others only when I do a format on the OS. To my sadness, it did not stop the constant D:OS crashes to desktop (some leading to BSoD). More often than not the crash reports would indicate some issue with the C++ Library, or just the game's .exe, but other times I would catch an "This device drive has stoped working" from my GPU.
After trying everything I could think of, I started going after the game's graphics settings, and to my surprise, changing the resolution seemed to solve the issue. I have an 1360x768 display monitor, but was always playing the game on 1280x720 resolution, non scaled, for performance boost. So when I changed the game's resolution to my monitor's native, it did stop the crashes alltogether.
Before I would crash about 2, 3 times in an hour. But now I can play for hours without having a single CTD. it's magic!
Just sharing the info with you guys. Maybe someone is having similar problems and would find my solution also fixes it for them? Maybe it's the game's fault? Maybe it's my hardwares or softwares? Don't know. I just have not seen this mentioned anywhere as a fix, and totaly worked for me.
Just felt like sharing. =)
