Profiling the E2E Delays of Streamed Video Games with the Camera Method. Technical Report (Master thesis), . Theiner, Markus. Master thesis. University of Würzburg, 2021, September.
- [ Abstract ]
- [ BibTeX ]
- [ EndNote ]
Determining the E2E lag of actions in video games is not trivial since there is no built-in way to grasp the full lag, including that contributed by the input and output. A standardized method is to record both input and output with a high framerate camera and count the frames from a visible input event to the result on screen. Your job is to perform these measurements for different actions in a series of games, and examine the overhead game streaming generates for them. Note: It might currently not be possible to perform these experiments, as they rely on a physical testbench.

Evaluation of the Movement Synchronization of Unreal Engine 4. Technical Report (Master thesis), . Gölz, Joseph. Master thesis. Universität Würzburg, 2018, September.
- [ Abstract ]
- [ BibTeX ]
- [ EndNote ]
The Quality of Service and associated Quality of Experience that networked games provide to a user are susceptible to many inﬂuences. Network conditions are a known factor, when it comes to evaluating the synchronization of clients that partake in the same game, as well as the server. Compared to prior work, that either only focused on a small parameter space or used theoretical approaches that did not factor in the eﬀects diﬀerent game and engine settings can have, this was the target of this thesis. By implementing a fully automated testbed, utilizing an Unreal Engine 4 game prototype, a multitude of diﬀerent parameter sets could be tested and evaluated. This was done by observing character locations and replicated movement information, and printing them to log ﬁles. Instead of querying humans for perceived QoE, spatial and temporal diﬀerences between replicated characters and their movement was measured. When evaluating these measurements, insights regarding parameter dependencies and critical measurement inﬂuences were gained. This for example includes the necessity of an advanced, uniﬁed character movement model to improve evaluation potential.

Measuring the Effectiveness of Latency Mitigation Methods with a Prototype Video Game. Technical Report (Master thesis), . Leidinger, Ferdinand. Master thesis. University of Würzburg, 2022, February.
- [ Abstract ]
- [ BibTeX ]
- [ EndNote ]
Video games with a competitive multiplayer modes must deal with the troubles of high and varying end-to-end lag. They can employ varying methods to manage, mitigate or conceal this lag and equalize it between different clients. But the closed source nature of video games makes examining the effectiveness of these mechanisms hard. Your job is to implement a simple video game prototype from scratch that uses an authoritative client-server multiplayer approach and implements such lag mitigation mechanisms. With this prototype we want to get a better understanding of the effectiveness of these lag concealment measures.
