Hi, I know it's a year late, and sorry for reviving the thread. I was facing the same problems and came by a possible solution for anyone else who may be looking to fix the flickering, water splashing, and swimming/floating issues. You would want to download this file: https://www.guru3d.com/files-details/nvidia-inspector-download.html and follow the instructions in this video (the video is not mine, kudos go to the original owner of the video zzFuzzy): https://www.youtube.com/watch?time_continue=273&v=JWRp-dIqqhc Hope this helps anyone else looking at this thread now, and into the future. Regards.
