This page offers information on how to use V-Ray 5 Benchmark.
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.
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.
You will be presented with a Freeware Benchmarking License Agreement window, where you should acquaint yourself with the License Agreement in order to proceed.
The License Agreement will always appear the first time you run Benchmark. Once you agree, it will not re-appear upon next launch.
If you want to automate your agreement using command line, use the following commands:
You are presented with three options: V-Ray (utilizing the CPU), V-Ray GPU CUDA (utilizing your CUDA devices) and V-Ray GPU RTX (utilizing your RTX devices).
Note that V-Ray, V-Ray GPU CUDA and V-Ray GPU RTX are different render engines in V-Ray Benchmark.
Under V-Ray GPU CUDA and V-Ray GPU RTX you have the freedom to choose which devices to benchmark. Your CPU is also considered a CUDA device and can be tested in a hybrid mode.
Each of the tests runs calculations for exactly 1 minute.
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 version has one single executable for both GUI and command-line usage.
Linux: 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.
The table below contains a list of all available options for using V-Ray Benchmark:
|--dump||-d||Logs debug output||vray-benchmark-5.00.00-cli.exe --mode vray --dump|
|--list-devices||-l||Lists the available devices for the picked mode||vray-benchmark-5.00.00-cli.exe --mode vray-gpu-cuda --list-devices|
|--with-devices DEVICES||-w DEVICES||Picks devices for rendering. DEVICES is a comma-separated list of device indices||vray-benchmark-5.00.00-cli.exe --mode vray-gpu-cuda --with-devices 0,1|
|--mode MODE||-m MODE|
Picks a mode for rendering. MODE can be: vray, vray-gpu-cuda, vray-gpu-rtx.
|vray-benchmark-5.00.00-cli.exe --mode vray-gpu-rtx|
|--output FILE||-o FILE|
Outputs the benchmark information to a .json file. FILE is an absolute path.
|vray-benchmark-5.00.00-cli.exe --mode vray --output D:\CUDA_cards.json|
Provides information about the current version of V-Ray Benchmark.
Displays a help message with the available command-line flags.
The command flags in the Option alias column in the table are shortened aliases of the commands in the Option column. You can use either of the aliases. Mixed usage is also possible, for example: vraybench_5.00.00-cli.exe -l --mode vray
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.
If you experience trouble launching V-Ray Benchmark under Windows (GUI or CLI), it might be due to invalid performance counters. They can be reloaded by running the cmd as administrator and executing the following commands:
