- Developed a Vulkan layer to measure input latency using synthetic input and present timing.
- Used the layer to analyze CPU-bound and GPU-bound scenarios, showing how anti-lag reduces latency.
- Tested FIFO buffering cases on fixed refresh rate monitors and streaming latency for remote gaming.
- Explored experimental anti-lag techniques for fixed refresh rate systems to optimize compositor deadlines.
