![]() In that case, the total elapsed time for the combined VR Game and VR Runtime is too long, and the frame will not be ready to display at the beginning of the next scan. The job of the Runtime becomes significantly more complex if the time to generate a frame exceeds the refresh interval. The following figure shows what this looks like in a timing chart. Two of these interesting modifications include color correction and lens correction, but the work done by the VR Runtime can be much more elaborate. The VR Runtime reads the new texture, modifies it, and generates a final image that is displayed on the headset display.The game then establishes a graphics frame, and the GPU renders the new frame to a texture (not the final display).The VR Game samples the current headset position sensor and updates the camera position in a game to correctly track a user’s head position.When timing requirements are satisfied and the process works correctly, the following sequence is observed: VR software for delivering frames can be divided into two parts: the VR Game and the VR Runtime. ![]() 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. There are, however, a couple of bugs and general clunkyness with the VR support atm (cutscenes in particular).Īlso note that smooth locomotion is required for the most part.īesides SS Fusion being unstable with custom maps/gametitles, the maps in this mod were designed for singleplayer gameplay, It's likely that you run into issues when playing online.By Andrew Burnes on Wed, Featured Stories, While the main idea is to recreate the classic Duke 3D experience, some modern elements are added to the mix, such as redesigned and expanded level areas, occasional enemy waves/arena fights and new weapons.Īlso features redesigned enemy and weapon models from DNF with custom animations, as well as a selection of sounds and voice taken from several official Duke games and beyond that lots of custom assets and music tracks made exclusively for this mod.įor playing in VR, Serious Sam 3 VR edition is needed. Serious Duke 3D is a reimagining of the first episode of Duke Nukem 3D.
