Crashing at Thalla fight in Parisdiso

[Djentlemen]

Bought the upgrade for early acess and played 3 days no problem. THen on the 4th day my pc suddenly was getting to 90+Celcius and memory was at 97%. Ive spent 6 to 8 days every day after work or all day on an off day looking up soulutions. From registry keys to resetting my PC to favtory settings...twice! I finally got it to run at a decent pace. Graphics bumped down. No ray tracing, No NVIDIA Low Reflex, and while it looks worse and blurry i can actually play for 2 ish hours. It still crashes after a while. So i just take breaks occasionally. Cant get it to register on NVIDIA GEO but have been using Razer to try to boost and optomize. IVe even downloaded a memory optimizer and fan cooler booster/Analyzer, debating on buying the Pro verson if that will help.

But now im in paridiso trying to talk to do the main quest. And it UE Alabama crashes in the THalla fight..every single time. Sometimes its the beggining, sometimes the middle. and sometimes when hes below 20% health. But it has happened everysingle time. ONce right after i beat him, didnt give me time to save. And its the exact same place that first intially crashed forom overheating or running out of memory or really the first time I had actual problems. 

I dont know what else to do. I am a huge Obsidian fan. Ive played pretty much all their Rpgs for the last 20+ years. Im loving the game. But ive given up. I cant find any new info. Or any rumors of someone fixing it. Im waiting on a Fat32 format USB to come in so i can try to update BIOS. Which ive never done. Cause thats the last hail mary ive got. 

If anyone has any news or suggestions Id very much appreciate it. But im at a loss. Ive spent days of real time just trying to get the game to work for more than 5 to 10 mins. And ysterday i thought i fixed it. Oh how wrong i was
