For best results, close any extraneous running apps from your system (such as web browsers, 3d applications like 3ds Max or Maya, etc) and restart to give the benchmark full use of your system resources (CPU usage, RAM, etc.) before running. If you are using a laptop, it is recommended to switch on your power adapter for maximum performance.

To launch the GUI and begin benchmarking your system's performance, simply run the application. There is no need to install it, it can run from anywhere, including USB keys and network locations. You will be presented with a Freeware Benchmarking License Agreement window, where you should acquaint yourself with the License Agreement in order to proceed.  

Once the application loads, click the Start button to launch both the V-Ray and V-Ray GPU benchmark tests from the launch screen shown below.

You can toggle switch between the two tests by either testing V-Ray (utilizing the CPU) or V-Ray GPU (utilizing your CUDA devices) engine. Note that V-Ray and V-Ray GPU are two different render engines. Under V-Ray GPU you have the freedom to choose which CUDA devices to include in the test. Your CPU is also considered a CUDA device and it can be tested in a hybrid mode.

Each of the tests runs calculations for exactly 1 minute.

titleCommand-line Usage

 

V-Ray Benchmark can also be used with a command-line interface, making it suitable for benchmarking machines that have no monitors connected, such as render farms. Navigate to the location of the OS-specific application using a system console (or terminal), and execute the benchmark application.

V-Ray Benchmark tests the performance of the machine where it is started. Testing render farms would require running V-Ray Benchmark on each farm machine to get the performance result of your farm.

V-Ray Benchmark for Windows comes with two separate executables - one for GUI usage, and another one for command-line usage.

The Linux and macOS versions have one single executable for both GUI and command-line usage.

 

The table below contains a list of all available options for using V-Ray Benchmark:

OptionOption aliasFunctionExamples
--quiet -qImplicitly agrees to the EULA and hide installer's outputvray-benchmark-4.10.03-cli.exe --quiet
--dump-dLogs debug outputvray-benchmark-4.10.03-cli.exe --quiet --mode both --dump
--list-devices-lLists the available V-Ray GPU devicesvray-benchmark-4.10.03-cli.exe --quiet --list-devices
--with-devices DEVICES-w DEVICESPicks V-Ray GPU devices for rendering. DEVICES is a comma-separated list of device numbersvray-benchmark-4.10.03-cli.exe --quiet --mode vray-gpu --with-devices 0,1
--mode MODE
-m MODE
Picks a mode for rendering. MODE can be: vray, vray-gpu, both.
vray-benchmark-4.10.03-cli.exe --mode both
--output FILE-o FILE
Outputs the benchmark information to a .json file.
vray-benchmark-4.10.03-cli.exe --mode vray --output
--version-v
Provides information about the current version of V-Ray Benchmark.
vray-benchmark-4.10.03-cli.exe --version
--help-h
Displays a help message with the available comman-line flags.
vray-benchmark-4.10.03-cli.exe --help

The command flags in the Option alias column in the table above are simply shortened aliases of the commands in the Option column. You can use either of the aliases. Mixed usage is also possible, for example: vraybench_4.10.03-cli.exe -q --mode both

 

To run V-Ray Benchmark through the command-line interface, just pick a rendering mode or run the file (in which case the all mode will automatically be chosen). You will then be prompted to accept the End-User License Agreement, after which the benchmark will begin. Keep in mind that multiple flags can be used simultaneously.

 Linux and macOS: Executing V-Ray Benchmark without a flag will force its GUI to appear. If you wish to run a benchmark without the GUI, you have to specify the rendering mode explicitly in your command-line tool.

You can start a new test (for example, to select different CUDA devices) by pressing the Start a New Test button on the results screen. You can also see the log file (in a text format) of your test renders by following the View log file link.
