VSYNC is enabled to prevent tearing, since tearing in the HMD can cause major discomfort to the user. Today’s leading high-end VR headsets, the Oculus Rift and HTC Vive, both refresh their screen at a fixed interval of 90 Hz, which equates to one screen refresh every ~11.1 milliseconds (ms).

If you wish to benchmark a system with FCAT VR the testing itself is straightforward, though setting up analysis of benchmark data does require a few steps. Using this data FCAT VR users can create charts and analyze data for frametimes, dropped frames, runtime warp dropped frames, and Asynchronous Space Warp (ASW) synthesized frames, revealing stutters, interpolation, and the experience received when gaming on any GPU in the tested Virtual Reality game.Īn example of the VR FCAT’s performance charts
With FCAT VR, we read performance data from NVIDIA driver stats, Event Tracing for Windows (ETW) events for Oculus Rift, and SteamVR’s performance API data for HTC Vive to generate precise VR performance data on all GPUs. Today we’re releasing FCAT VR, enabling reviewers, game developers, hardware manufacturers, and enthusiasts to reliably test the performance of Virtual Reality PC games, where fast, smooth performance prevents stuttery unresponsive gameplay, which can lead to eye strain and discomfort.īefore now, Virtual Reality testing relied on general benchmarking tools, synthetic tests, and hacked-together solutions, which failed to reveal the true performance of GPUs in VR games. Now, the best GPUs are those that are fast and smooth, giving gamers a far more enjoyable experience in every game. With FCAT, performance could for the first time be measured in intricate detail, revealing micro-stutters, dropped frames, incorrect multi-GPU framepacing, and much more. In 2013 NVIDIA revolutionized graphics card benchmarking with the release of FCAT, a free tool that enabled gamers and reviewers to test not only FPS, but also the smoothness and quality of gameplay on all GPUs.
