I'm not sure what is the cause, again after more testing, setting graphic to high laptop and gpu core and memory clock down -400mhz I have no crashes in that extreme fight. The weird thing is after a full instance session I placed back all to normal with max graphic settings and didn't had issue. Next day I relogged in game and went in extreme fight and had the crash again, so I changed it BACK again (with msi afterburner) the core and memory clock and lower graphic again and didn't had issue all day. There's something in that fight that I suppose at max settings make crash directx. I'm also using prefer max performance on nvidia panel and is not from steam. Until found a solution I guess I have to play with underclock gpu... not that in the end matter much but still sucks.

EDIT: GPU in the fight didnt pass above 75°C degree and cpu were at 69°C max I seen.
