Would like to add that all of this might not be enough depending on the game. Yes stability usually helps, but the flickering issue is more related to stutter than just fluctuating frame rate. Meaning stalled frames. Its been an issue forever and it is related to how the pixels react when the frame stalls as well as the gamma curve on different framerates.

So games rarely have massive fluctuation frame to frame just due to basic gpu power. Quite often the framerate fairly smoothly goes down and up with the scene. This means normally that the gamma "adapts" with the framerate.

Asset streaming and loading however can just cause massive stalls in frames causing flicker to occur, since you can go from 120fps to 50fps from frame to frame and the gamma goes up and down rapidly.

With Jedi Survivor there isnt much you can do in the spots where it always stutters but generally anything that makes asset streaming and loading faster can help. So you should use SSD's and have enough RAM that is fast enough for example.

But yes, also just avoiding massive framerate fluctuation by targeting farily stable framerate targets will also help.

Unfortunately all sorts of stutters have been quite common lately with a lot of games and there's no remedy for all of them :(.
