voglperf

Benchmarking tool for Linux OpenGL games. Spews frame information every second. Example:

##############################################################################
Voglperf framerates from pid 12106.
##############################################################################
3564.35 fps frames:3567 time:1000.74ms min:0.23ms max:14.72ms
4144.01 fps frames:4145 time:1000.24ms min:0.23ms max:1.20ms
4037.20 fps frames:4038 time:1000.20ms min:0.23ms max:1.20ms
4059.60 fps frames:4060 time:1000.10ms min:0.23ms max:1.09ms

Can also write frame times to a log file which can then be graphed with gnuplot, etc.

Building

We use cmake and the voglproj binaries are put into the bin directory. A Makefile is included to simplify this a bit and see how cmake is launched.

To build amd64 and i386 packages:

make

To build just i386:

make voglperf32

To build just amd64:

make voglperf64

To delete the build32, build64, and bin build files:

make clean

Building voglperf on SteamOS

• Click "Settings" on top right.
• Click "Interface" on left.
• Check "Enable access to the Linux desktop".
• Head back to main menu, click "Exit", "Return to Desktop" (or hit ctrl+alt+F8)
• Click "Activities" on top left, then "Applications".
• Click "Terminal" icon.
• Type passwd and enter a password.

• echo "deb http://ftp.debian.org/debian wheezy main contrib non-free" | sudo tee -a /etc/apt/sources.list
• sudo apt-get update
• sudo apt-get install git ca-certificates cmake g++ gcc-multilib g++-multilib
• sudo apt-get install mesa-common-dev libedit-dev libtinfo-dev libtinfo-dev:i386
• sudo apt-get install libedit-dev libedit-dev:i386 libncurses5-dev libncurses5-dev:i386 libgcc-dev libgcc-dev:i386 lib32gcc-dev libgcc-dev libstdc++-dev libstdc++-dev:i386

• Get the volgperf source:

• git clone https://github.com/ValveSoftware/voglperf.git

• Build:

• cd voglperf
• make

Run voglperf on SteamOS

• Run voglperf as "steam" user.

• sudo -u steam bin/voglperfrun64

• You should see something like:

• Starting web server...
• Started http://172.16.10.93:8081

• Double click "Return to Steam" (or hit ctrl+alt+f7)
• Connect to voglperf url with Chrome or Firefox browser from another computer.
• Browser should show something like:

Connected to ws://172.16.10.93:8081/ws  
  Welcome!

Gameid: ''  
    WS Connections: 1  
    logfile: Off (Launch option)  
    verbose: Off  
    fpsspew: Off  
    fpsshow: Off (Launch option)  
    dry-run: Off (Launch option)  
    ld-debug: Off (Launch option)

    debugger-pause: Off (Launch option)

• To launch TF2, do:

• game start 440
• Click OK button on "Allow game launch" dialog.

• Full AppID game list: http://steamdb.info/linux/

• To capture logfile for 10 seconds, type:

• logfile start 10 ;

• Should see something like:

• Logfile started: /tmp/voglperf.Team-Fortress-2.2014_04_01-06_28_16.csv (10 seconds).

• Logfile stopped: http://172.16.10.93:8081/logfile/tmp/voglperf.Team-Fortress-2.2014_04_01-06_28_16.csv

• Right click on logfile link and say "Open in New Tab" (or whatever).

Run vogl w/ SSH on SteamOS

• Run ip addr and note IP address of your SteamOS box.

• ssh desktop@127.16.10.93
• cd voglperf
• sudo -u steam bin/voglperfrun64
• Run various commands:
  • help
  • status
  • showfps on
  • game start 440
  • etc.

Notes

• HTML needs to be cleaned up.
• Occasionally web client will think two clients are connected and duplicated messages. (Needs to be tracked down.)
• We are currently adding voglperf as a SteamOS package.

Logfiles

Display graph in gnuplot (install gnuplot-x11):

gnuplot -p -e 'set terminal wxt size 1280,720;set ylabel "milliseconds";set yrange [0:100]; plot "/tmp/voglperf.Team-Fortress-2.2014_02_13-13_06_20.csv" with lines'

Output graph to blah.png:

gnuplot -p -e 'set output "blah.png";set terminal pngcairo size 1280,720 enhanced;set ylabel "milliseconds";set yrange [0:100]; plot "/tmp/voglperf.Team-Fortress-2.2014_02_13-13_06_20.csv" with lines'
