Now, Microsoft has finally acknowledged the problem, stating that it is looking into the factors that can potentially be causing games to stutter.
According to reports on Nvidia's forums, gamers have been experiencing frame-rate drops and stuttering in various games like Overwatch, Rocket League, and Battlefield 1, even on high-end machines that should be able to handle the aforementioned titles with ease. These users claim that this issue was not present prior to the Creators Update - made available in April 2017 - which also includes "Game Mode" for better performance in games.
A Microsoft engineer has acknowledged the issue on Feedback Hub, saying that:
Thank you everyone for providing feedback and submitting traces. We have been analyzing the traces from your feedback and have identified several different problem sources surfacing as stutter in games. We have a fix for one of them in the Windows Insider build that flighted to the “Fast” ring (build 16273 and above). You can find instructions on joining the Windows 10 Insider Program here: https://insider.windows.com/en-us/how-to-pc/. We are actively investigating the remaining stutter causes and appreciate your patience on this issue.
It is important to note that build 16273 was released to Insiders near the end of last month, and supposedly includes fixes to only one of the issues identified by Microsoft engineers. That said, gamers will be pleased to know that Microsoft has launched a full investigation in order to determine the other sources of the problem. However, with the Fall Creators Update just around the corner, it is likely that any fixes that Microsoft develops will be made available in the feature update, rather than a cumulative update at this stage. We have reached out to the company for clarification and will update if it responds.
