What is V-Ray Benchmark

V-Ray Benchmark is an application that tests your system resources to gauge how well your system renders V-Ray scenes using both the CPU and the GPU. Through a standalone executable, users can run V-Ray Benchmark to score how fast their system can render some sample scenes of common V-Ray uses without having V-Ray installed. Results can be submitted to an online site that aggregates all submitted system specifics and their scores for comparison sake. This is useful for making decisions on upgrades and allocating system resources as required. Also, it's just pretty cool!

  • Benchmark your system from CPU to GPU
  • Post scores and compare with other system builds to
  • Tweak or upgrade components and see their real-world impact
  • Runs on Windows (Windows 7, 8, 10), Linux (6.2 WS, Fedora 14, CentOS 6.2 and later), and OSX (10.8.5 and later)
  • Does not require a V-Ray installation or license

GPU Rendering

A hardware with at least 2048 MB of RAM is required for benchmarking your GPU. The GPU benchmark option will not be available unless this requirement is fulfilled.



Where to Download

Click the link below to download V-Ray Benchmark. Once you log in to your account, you can download V-Ray Benchmark for the desired operating system as an executable file that may be placed anywhere on your machine to be run directly. There is no licensing or installation required, but please do read through the license agreement once you launch the application.



Using V-Ray Benchmark - GUI application

For best results, close any extraneous running apps from your system such as web browsers, 3d applications like 3ds Max or Maya, etc. to give the benchmark full use of your system resources (CPU usage, RAM, etc.) before running. There are two ways of benchmarking your machine - using the dedicated GUI application, or alternatively through the command-line interface.

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. Once the application loads, click the Start button to launch both the CPU and GPU benchmark tests from the launch screen shown below. First, the CPU test will render and display the benchmark time, and then the GPU test will render and display its time.



Clicking the CPU or GPU icon above the Start button enables only one test at a time when the Start button is pressed to launch only that selected benchmark.

Using V-Ray Benchmark - Command-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 Mac OS X 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 agree to the EULA and hide installer's outputvraybench_1.0.8_win_x64-cli.exe --quiet
Picks a mode for rendering. MODE can be: cpu, gpu, or all.
vraybench_1.0.8_win_x64-cli.exe --mode=all
Provides debug information while rendering.
vraybench_1.0.8_win_x64-cli.exe --mode=cpu --dump
Provides information about the current version of V-Ray Benchmark.
vraybench_1.0.8_win_x64-cli.exe --version
Displays a help message with the available comman-line flags.
vraybench_1.0.8_win_x64-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_1.0.8_win_x64-cli.exe --mode=all -q


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 OSX: 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.



Command-line usage examples:



vraybench_1.0.8_win_x64-cli.exe --mode=all


Mac OS X:


$ hdiutil attach vraybench_1.0.8_osx_x64.dmg
$ cd /Volumes/V-Ray\ Benchmark/V-Ray\
$ ./V-Ray\ Benchmark --mode=all




$ ./vraybench_1.0.8_lin_x64 --mode=all




Interpreting the Results

The benchmark results show as elapsed time for the CPU and/or GPU rendering of the respective scene in minutes:seconds. Lower scores denote better performance and better bragging rights.



Submitting your Results

Once you have run the tests, you can click the Submit button to send your scores to for a comparison with other systems.




You will need to sign in with your Chaos Group account to complete the submisison process.




Once you have signed in, you will be presented with your results in a table with results from others.




If you return to V-Ray Benchmark, you will see that it confirms your results have been successfully submitted.




The Start button from before is replaced with a Restart button you can use if you want to run more tests.
