After Steam was updated, Voglperf don`t work
.

ERROR: Could not retrieve pid of launched game.

In some distros it is better have a make install target.
I am working on an ebuild and i have no clue as to what files are useful or not.
So i am just assuming everything in bin/ needs to be installed.

With microsecond accuracy.

csv file example:

# frame number, frame end timestamp with microseconds, frame time microseconds
1,1489260325.123444,5123
2,1489260325.129121,6777
3,1489260325.135912,5555

This will allow graphing with x axis as a time. This will also allow averaging in time, doing various smoothing algorithms (exponential moving average, moving averages in time, max and min over last 5 seconds, etc), instead just in frames, additionally it allows many other things, like creations of histograms, cumulative distributions, etc, properly normalized between files with different numbers of frames, or with different sections of single play / benchmarks, split on time, and not frames.

Also, the fact that the voglperf show some min/max statistics in the header, means to me, that the file is not being written, until the game ends or logging period ends.

Instead the file should be streamed, and the statistics should be dumped at the end. This way there is no overhead of buffering this in memory. Writing to the file can be done asynchronously from a separate thread with some small buffering if needed. Users can put it in tmpfs, or just leave it to the kernel to flush it really to a disk, so there should be no significant performance impact.

Voglperf seems to have trouble finding the PID of the started game:

Hi,

I'm running voglperf 64 bit with the command:
bin/voglperfrun64 --verbose

But on the webpage I get the error:
ReferenceError: WebSocket is not defined

I don't understand your licensing. Your README says the code is under the MIT license, but in your license file you call it "VOGLPERF CODE LICENSE". The body of the LICENSE seems to be a copy of the MIT license, but everybody has to check it word-by-word now since you gave it a different name. Also in the header it says "All Rights Reserved", which is not compatible to the MIT license, so that statement doesn't make any sense.

If this should have been the MIT license, please just use the MIT license (https://choosealicense.com/licenses/mit/) and replace "[year] [fullname]", but nothing else.

Hi,

Actually, there is a bug for the Witcher 2 with keyboards and we must to set "LC_ALL=C %command%" in the Launch Options for this game to play correctly.

Problem with voglperf, when i launch the game with it, the option set in steam is not use by voglperf. This is the launch command use by vogleperf :

steam steam://run/20920//VOGLPERF_CMD_LINE="--msqid=0 --showfps" LD_PRELOAD=/home/berillions/Desktop/voglperf/bin/libvoglperf32.so:/home/berillions/Desktop/voglperf/bin/libvoglperf64.so:$LD_PRELOAD %command%

You can see that "LC_ALL=C" is not used...
How to fix this problem ?

Thanks,
Max

HI dear author,
It's truly a honor to write a letter to you, I'm building your project nowadays and found the error when building as following, I wonder if there is a chance that you know the reason? :)

thank you
best regards to you

I have tried using fpsprint on, however nothing spews out to console nor the browser.
Tried both with Dota 2 and CS:GO

logging works but i want frames.

Starting web server...
ERROR: Web server failed to initialize.
i got this error when i run:
sudo -u 'username' bin/voglperfrun64
any help??

When trying to compile for x86 i receive the following error.

/usr/bin/ld: cannot find -lpthreads collect2: error: ld returned 1 exit status

Here's my system:

When I try to make the package on Fedora 23 I get the following error:

My application is rendering frames in about 100-200μs each, at times, and sometimes when the frametimes are around there, voglperf's log files will have an extra "0." before a frametime line. It looks like:

...
0.13
0.17
0.0.17
0.20
...

And I'm not sure exactly how that comes about.

libtinfo on many systems is just a symlink to ncurses.

Hi,

Running in Ubuntu 15.04 64bit, I have tried both voglperfun32 and voglperfrun64 and neither seem to be able to locate steam. It is installed, and can be run from a terminal by simply entering steam.

This is what the Terminal spits out when voglperf cannot locate Steam:

Steam is installed, and runs without issue. Running games is also fine (Cities Skylines, Borderlands the Pre-Sequel, CSGO).

Its some about /libGL.so? Hmm i have installed fglrx driver and have default mesa pack - stock in my system but why this error present? BTW. sorry for bad english translation :)

voglperf build tries to link libSDL2 library statically to voglperf's LD_PRELOAD library.

LD_PRELOAD is shared library. Shared libraries are compiled as position independent code, with -fPIC. Static libraries (in general) aren't, in the distributions. Because of this, voglperf compile fails, GCC doesn't (anymore) allow shared objects to have TEXT relocations.

I guess by static linking you try to avoid conflicts with Steam games that also link libSDL2, but the correct solution is just not using SDL2 in the LD_PRELOAD.

Your preload library is really simple, there's nothing that needs SDL2, all that functionality is already easily available in C library.

Of the SDL functionality you're using, these are just wrappers for libc functions:

• SDL_memset()
• SDL_isspace()
• SDL_getenv()
• SDL_strstr()
• SDL_snprintf()

And rest are trivial to change to use standard C-library POSIX functions:

• SDL_Delay() -> nanosleep()
• SDL_LoadObject() -> dlopen()
• SDL_LoadFunction() -> dlsym()

Following instruction from voglperf main github page for steamos (https://github.com/ValveSoftware/voglperf#building-voglperf-on-steamos) when intending to build 32 and 64 bit packages with make there appears to be 64 bit build only. What i see when building with make is

I have not worked out what i need to do to get both 32bit and 64bit builds available for voglperf and posted here because of the unexpected behaviour of voglperf.

SteamOS is the latest beta build 133.

Within Ubuntu (and many other Linux variants) it is possible to use the package libedit-dev to provide necessary headers and libraries for building voglperf.

Hi,

I've been runing Voglperf to check out the Witcher 2's performance on Ubuntu 14.04 64bit. The issue I'm running into is that the font size for the OSD of frames-per-second is very very small. I am running at 1920x1080 on a 25" screen.

Is there a current way to increase the font size? I am using release 0.2, and have been scouring the source code, but see no section for text size that can be modified (I've only skimmed through the code though).

Whilst the font size is the most important at the moment, the color of the font is also hard to see (dark red). Any assistance or guidance is greatly appreciated!
