Now this is very interesting.

I couldn't crash the graphics driver on Ballitic's Sandbox where I normally could do it within 2 minutes, now I was able to fly steadily for quite some time. Temperature rose from the normal 50'C I have on desktop to something around 65'C.

I started feeling overconfident so I went back to campaign to drive a truck with some guerillas and I saw the temperature sit nicely at around 70'C but the GPU Usage was bouncing around 60-80%. Then it finally started rising to 99% where I decided to pause the game. It showed no signs of decreasing so I continued on with the game but stopped the vehicle and turned of its headlights.

The Usage started to drop.
It decreased to around 80% before I tried to carry on with the mission but the driver crashed shortly afterwards with the log stating GPU Usage being 99% again.

Max GPU Temp: 77'C
I am no expert but I think that's within safety standards.

Thank you for your help.
I wouldn't have gotten anywhere solving this problem alone.

I'm going to try if I can reach the same usage percentages with any other graphically challenging games and maybe try disabling the Intel card somehow to see if it has any effect on gameplay and/or stability.

It seems the MSI stopped giving the option to monitor GPU temperature when I started it up today. I have no idea why but that's not a big issue anymore.

Arma 3.cfg uploaded as a .txt as .cfg is not allowed. Should be readable nevertheless.

The MSI Afterburner I installed is version 2.3.1 as well.

Thank you for your response.

I must disagree with you when it comes to my laptop being strong enough. To my mind the word "incompatibility" is more fitting. What's strange here is that it worked once but is not compatible anymore.
This might sound like a rant but updates shouldn't make a game unplayable as far as I know.

"It's most definitely a hardware issue. "
I agree.

If I remember correctly I haven't had graphics driver crashes in any other game or application.

Back to the MSI:
Suddenly, without any warning when I started up the Afterburner for the first time in 3 days, an option for GPU Temperature showed up and it was enabled by default.

I will upload information regarding the GPU temperature shortly.
Meanwhile here is a picture of the MSI main screen. As you can see there is no information of the driver version.
The settings there have not been changed at all. Both Core Clock and Memory Clock were maxed by default.

I uploaded a picture of my MSI Afterburner settings as well as 3 pictures of my Arma 3 settings. They're in the attachments now.

The first mentioned picture shows that there is no option to enable GPU temperature monitoring, only GPU usage, fan speed and the framerate twice, or it might be just me being completely blind.

The three other screenshots in the Arma 3 Settings.rar show that I have nothing special enabled (AO, Caustics, FSAA, ATOC, PPAA, Aniso. Filtering, Bloom, Blur).

Looking forward to your reply.

Thank you very much for your answer.

I downloaded and installed the MSI Afterburner but didn't find an option to monitor temperatures, only fan speeds and GPU usage.
However, what I did find is that the GPU usage stays around 30-50% when playing Arma 3 during the night mission and then it rises to 99% for the duration of the driver crash.

I uploaded the hardware monitoring file. It's just a text file as .hml files are not allowed to be uploaded here. It clearly shows the GPU usage rising.

To answer your question, No, I did not experience these crashes prior 1.08.
I was able to play fine since the Beta started (Alpha didn't work at all) for many hours.

I know that Arma 3 can be quite a challenge for my poor little laptop but I'm not sure if that's the issue here, as I was able to play this game nice and easy before 1.08 emerged. Something in that patch changed the game radically for my graphics driver.
