Ok so yesterday I did further testing. I started MSI afterburner, setup core and memory clock down to -400mhz, changed game graphic from max settings to high laptop. I started doing 72 ppl PVP, game didn't crash once (I assume because I had people effects off), then I went Storm's Crown Normal, didn't had crashes there. So I went to continue build my isle, been hours there then decided (because looked safe) to try again Extreme Trial. While on background I had skype, discord, RGB Fusion 2.0 (gigabyte rgb program) microsoft visual studio code and msi afterburner I went in the fight. I had the whole duration of the instance without a single crash. We went out for repair, I changed back to default the graphic settings to max and the gpu memory and clock back to default. We went in again, didn't had crashes. The party disbanded, were late for EU party so I went in NA with my other character, did Extreme Trial there. The game didn't had any DX crashes in the fight for hours. Today I log in and join a extreme trial party, this time I had same programs but didn't start MSI afterburner because though didn't need anymore. And thats where I were mistaking... the fatal error happened again out of the blue. So I changed back the core and memory down to -400 and graphic to high laptop, did few more pulls then and didn't seen crashes. However party disbanded and need more testing. According to MSI afterburner, unless 75° for a GTX 1080 is high while playing at max settings I didn't seen anything overheating. My cpu can reach high ° when playing certain games and still is fine (as AMD said is normal that this cpu reach high °), but so far FFXIV didnt reach high level of temps compared to games like phantasy star online 2 NGS for example were that one can reach 88° when to many players and stuff in fights or city. I have try all solution above, included opening my gpu, clean radiator and fans from dust and changed thermal paste. Windows were formatted to new days ago. Drivers are updated because I personally went download them after unistal the one that windows installed. Aside from extreme trial, I had game freezing crashing (tho I don't remember if were direct x crash there) in P1S months ago and most of the times that crashed were during boss punching with the chain sound the floor. I'm pretty sure I can stay in my isle all day without a single crash and so I guess in limsa too despite many players. I don't think I have dx crashes in duty roulette expert for example, I never seen once there. The game is palyed borderless fullscreen, not that matter as it crashed also in windowed days ago.
