I did it, it's working now. After steam refused my refund request 2 times I was forced to make it work.
Took me several more hours, but here is how to fix the game: (at least for AMD grapihc cards)
1. Search for the JediSurvivor.exe ( e.g. under ..\Steam\steamapps\common\Jedi Survivor\SwGame\Binaries\Win64)
2. Open its Properties and activate Windows 7 Compability. Uncheck everything else and press OK!
(while you are at it, you can delete the 2 "Default_Startup...mp4" files e.g. under ..\Steam\steamapps\common\Jedi Survivor\SwGame\Content\Movies so the game starts faster)
3. Update your graphic card driver. DO NOT SKIP THIS! I am using a 6800 XT and the driver version 23.12.1 is working fine
4. Go to nexus mods and download the "May the performance be with you" mod installer here: https://www.nexusmods.com/starwarsjedisurvivor/mods/7?tab=files
5. Unpack the mod, run the installer, browse to the game location (e.g. under ..\Steam\steamapps\common\Jedi Survivor)
6. Then choose the "normal" or "normal 80" preset (2nd is for higher quality)
7. Check "Limit pool to VRAM" , "AO Culling and RT Crashes Fixes" and "Use Experimental Stutter Fixes" then press install
8. Now start the game and open task manager. In the details tab right click the JediSurvivor.exe and give it "High" priority
The last step you need to repeate every time you start the game
I hope this helps.
Unfortunately, that did absolutely nothing to help me. It still crashes in exactly the same place every single time without fail. And looking back at my log of attempted fixes, I've already tried that fix before.
I'm still getting the issue where, when loading the cutscene for landing on Koboh for the first time, game audio stutters, I get a single still-image frame of the ship doing what I presume is it's landing sequence, and then game crashes. Every time. Without fail.
