UPDATE 2/5/23: In the wake of strong criticism of the PC launch for Star Wars Jedi: Survivor, EA has revealed that patches are incoming for all versions of the game. Console patches are due imminently, while the PC version was updated yesterday. This is the start of a no-doubt long process to get the game into shape and the good news is that there is progress here. However, the bad news is that based on performance testing, little has been done to improve the stuttering issues that impact the game so heavily on PC.
Below, we've posted a quick video comparing CPU-limited performance from the village in Koboh, which we found to have profound stuttering issues in the launch code. In our testing with RT off (Respawns states that CPU optimisations apply with RT disabled), the general performance level improves by around 13 percent overall on a mainstream Ryzen 5 3600, paired with an RX 6800 XT. However, you will also note that the peaks and troughs in frame-rate occur in the same areas. More to the point, examining the frame-time graph shows that the stutter has the same intensity.
In some scenarios, this actually accentuates the stuttering effect - because the crash in performance is much the same as it was before, taking you to similar lows to the launch code, only in this case, the crash is coming from a higher average level of performance. It's good to see improvement to the PC code so quickly, but it's going to require time to get the game fully into shape.
