I made no progress on the light issue. I tried an Nvidia and non Nvidia computer. Messed around with the framerate and settings. Used all the renders. ​ I am posting a video to show the exact issue.

I swear I always get the most specific issue in dues ex. this also happen with all other conversation and mod is updated to most recent. I also tried using gog and downloading nameless mod on that, but no dice. I honesty don't have a clue how to solve this.

edit; for my poor spelling and apologizing for my video quality, I don't have any good recoding device, so I used my phone.

last edit I set the volume low as that was not the issue while recording, so there no sound issue and that why video has low volume.
