We can see that the DrawIndexedInstanced()Ĭall takes 211us to complete. Many third-party tools exist, but the Radeon Developer Panel that comes with the Radeon GPU Profiler has a Device Clocks tab under Applications which can be used to set a stable clock on AMD RDNA™ GPUs, as shown below: You may fix the clocks on your GPU to reduce this variance. But this trades lower power consumption for performance and can introduce noise in our benchmarks, as the clocks may not scale the same way between runs of our application. Most GPUs have a default power management system that switches to a lower clock frequency when idle to save power. This can be useful in gathering repeatable average frame time data for your level.Īnother technique for helping reduce noise in profile results is to run with fixed clocks. It will then shutdown automatically after a fixed number of frames. This means that, if you have your project set up to run a camera flythrough on startup, it will advance through the flythrough using fixed timesteps and a fixed random seed. Rather, it runs 211×60=12,660 frames using a fixed timestep of 1/60=16.67 milliseconds. The source code on a machine that has at least eight (8) gigabytes of RAM, with a multi-core processor having at least eight (8) cores (including hyperthreading).In the above example, benchmarkseconds is not wall-clock seconds (unless every frame of the demo runs at exactly 60 fps). If you want to shorten the time it takes to compile the Engine from source, we recommend compiling

To build the project, run make from the terminal.ĭepending on your system's specifications, it may take anywhere from ten minutes to over an hour to compile the Engine.

Now, run GenerateProjectFiles.sh from the terminal to generate your project files. Inside the root directory, run Setup.sh from the terminal to setup the files needed to generate the project files. Additionally, read about Hardware and Software Specifications, and make sure your system has at least one hundred (100) gigabytes of disk space before performing Unreal Engine (UE) development and support teams currently use the latest version of Ubuntu as a result, we may not be able to provide support for other Linux distributions (including other versions of Ubuntu).
