Stuttering Issue captured by CapFrameX tool

[RodroG]

Hello, I am a Chernobylite fan and one of the tech reviewers of BabelTechReviews (BTR) tech portal.

First, I want to congratulate The Farm 51 for allowing us to enjoy this fantastic and somewhat uncommon, and different first-person action-adventure RPG game. I'm enjoying the game a lot, and I recommend it.

With that said, I want to share with the developers and the game's community this feedback about stuttering issues.

Please, see the following CapFrameX analysis performance charts that clearly show the current stuttering issue while playing the game (3 aggregated runs, no outliers):

Here you can see the custom game benchmark sequence that I used for testing purposes:

Frametimes Capture & Analysis tool-related

• CapFrameX is used for capturing and analyzing the relevant performance numbers obtained from each recorded built-in or custom benchmark sequence.
  
• Consecutive runs until detecting 3 valid runs (no outliers) that can be aggregated by CapFrameX using the following method: Aggregate excluding outliers’,outlier metric (second, P1-1% FPS percentile), outlier percentage (3%, the % the FPS of an entry can differ from the median of all entries before counting as an outlier).
