Fcat analysis

If you accidentally moved it to the wrong spot, then simply select the line, right-click on the plot, and select Clear Times to reset the chart line.

Plot Region Clicking the Plot button will create charts for all of the data that has been selected. This is where you can filter, sort, and rename data. Making and Manipulating Charts Using the Mouse The plot lines can be easily moved around using the mouse. These column headers can be changed by selecting the drop down menu and selecting another column header to be filtered as shown below.

Let me state upfront that pretty much all software and scripts can be read out as source code and the simple truth is that the FCAT benchmark method can't see the difference in-between AMD and NVIDIA graphics cards as we look at rendered frames, we are not measuring inside the graphics card s. First off, microstuttering and related anomalies apply only to multi-GPU setups. It would have been better to move the lines first and then trim them by setting the region. You will now need to browse to the location of Python. One frame can take say 17 ms. We decided to set the region between 2 seconds and 12 seconds. Basically it is the opposite of FPS. Making and Manipulating Charts Using the Mouse The plot lines can be easily moved around using the mouse. Recommended Games For First-Time VR FCAT Benchmarking Our technical marketing team has worked closely with media outlets, hardware manufacturers and game developers to determine games and benchmark scenarios that are easy to get consistent results from and are easily accessible, helping you test the waters of FCAT VR benchmarking. Up-to a while ago nobody really cared that, and some of you perhaps think that is the best way to approach this. To install pyqtgraph: After installing Anaconda, open a command window with administrator privileges from any location. Below, you can view these recommendations. Close SteamVR. Reboot your system. This will allow you to manipulate the plot lines that you have selected.

Enable Allow interleaved reprojection. An Interval Plot makes it easy to see the synthetic and dropped frames that occurred in the VR application during SW capture.

Clicking Clear Selection will clear any of the data that has already been selected, and clicking Clear Files will remove all data from the data window. Basically, the time it takes to render one frame can be monitored, tagged and bagged.

So, when you take a number of seconds of a recording whilst tracking the number of frames per second, then output that in a graph and then zoom in, you can see the turnaround time it takes to render one frame.

However, there is no OpenGL support at this time. Setting this value to 0 starts the capture immediately. How can we accomplish that? Up-to a while ago nobody really cared that, and some of you perhaps think that is the best way to approach this. Select Python. The most important method is simply to experience VR and evaluate how it feels. Start a VR application. As such, a few applications are needed. Before you read onwards, this article is more a bit more scientific, complex and academic opposed to what you are used to. This is the folder that contains the subfolders as outlined above. We decided to set the region between 2 seconds and 12 seconds. This is useful when you have data outside the benchmark area such as menus. Data Region Click on a data row to select it, and click it again to deselect it.

Consider renaming the directory to reflect the GPU, game, and settings tested. The red bar will turn green to indicate benchmarking is in progress.

Clear Times Notice how the chart lines used in the example above are not properly aligned?

Then click on the chart using the right-mouse button to drop the yellow vertical line where you want the chart to be moved. So basically high-low-high-low-high-low-high-low. After clicking Move Dataset, the chart line will move to the area. Data Region Click on a data row to select it, and click it again to deselect it. Start a VR application. Using the folder structure above will make it easier for the FCAT VR Analyzer to properly fill in the elements based on your folder structure. We decided to set the region between 2 seconds and 12 seconds. So What Triggered All This? Ensure that all graphic drivers are properly installed. This will allow you to manipulate the plot lines that you have selected. Below, you can view these recommendations. The most important method is simply to experience VR and evaluate how it feels. Frametime mostly measures and exposes anomalies - here we look at how long it takes to render one frame. An Interval Plot makes it easy to see the synthetic and dropped frames that occurred in the VR application during SW capture. It's commonly described as latency.
