Apex legends hard crashes my computer

Hey @Zen0fex , I searched a litte for your problem. There some people having probems with their 1080ti, smiular artifacts like you.

I found this -> https://www.youtube.com/watch?v=WO2zNMnbIps 

and this -> https://forums.evga.com/GTX-1080-Ti-Game-crashes-and-artifacts-m2808676.aspx 

..... -> https://forums.evga.com/GPU-artifacts-a-motherboard-issue-or-GPU-issue-m2737884.aspx (look at the pics)

And look at this ("Hello you beautiful people of Reddit!

I have been having a problem that I can't seem to track down. While running more graphically intense games, regardless of graphics settings, will cause artifacting and eventually will freeze either the application or the entire system. While running benchmarks and system stress tests it does not have this behavior however.")

I am very sure that there is a problem with your graphics card, but for some reason the problem does not always show up.

One more thing you can try is, download msi afterburner, downclock your GPU memory and core and see if apex than works. Try -100 to -300.
