Oculus Debug Tool

The Oculus Debug Tool is a software utility developed by Oculus VR, the company behind the popular Oculus virtual reality (VR) headsets. It is used to diagnose and troubleshoot performance issues related to running VR applications on an Oculus headset, such as frame rate drops, stuttering, or other graphical anomalies.

Performance
The performance option allows users to monitor the performance of their VR headset and adjust various settings to improve the frame rate and reduce latency. This option provides real-time data on the frame rate, CPU and GPU usage, and other metrics. Users can adjust the supersampling and pixel density to improve the image quality or reduce it to improve performance. The performance option is an essential tool for developers who want to optimize their VR applications and games for different hardware configurations.

Graphics
The graphics option provides a range of settings to adjust the visual quality of the VR experience. Users can adjust the anti-aliasing, texture resolution, and other graphics settings to enhance the image quality. This option also provides advanced features like dynamic resolution scaling, which adjusts the resolution based on the GPU load to maintain a smooth frame rate. The graphics option is useful for users who want to get the best visual quality out of their VR headset and for developers who want to fine-tune their VR applications' graphics settings.

Experimental
The experimental option provides access to cutting-edge features that are not yet officially supported by Oculus. This option includes features like asynchronous space warp, which uses the GPU to interpolate frames and reduce latency, and fixed foveated rendering, which reduces the rendering workload by rendering the periphery of the image at a lower resolution. The experimental option is suitable for users who want to try out new features before they are officially released and for developers who want to experiment with new techniques and features.
