Start benchmark mode from command line

ektor5 commented 1 month ago

Description

In the preview version there is a "Benchmark Mode" that can be selected from Graphical Setting Menu, but I was unable to find any combination of Command Line parameters to start it automatically.

Using Benchmark Mode over Profile Mode is crucial for the following reasons:

Cannot set unlimited FPS anymore (--max_fps=999 is deprecated)
If setting Physics FPS to 1000, profiler seems to calculate FPS over that, not the actual rendering (look below)
Better reproducibility with replay than with random kart laps

The idea is to start it from Phoronix Test Suite or any automatized testing. Is there a way to start "Benchmark Mode" from command line?

Additional information

When using Profile mode, the output of Average FPS seems bound to Physics FPS set in stk_config.xml MangoHud reports way higher numbers while rendering.

e.g. FPS = 120

[verbose  ] profile: Number of frames: 7805 time 66.822006, Average FPS: 116.802841

e.g. FPS = 1000

[verbose  ] profile: Number of frames: 65005 time 67.519005, Average FPS: 962.765991

Profile Mode command line:

./supertuxkart --no-start-screen --xmas=2 --easter=2 \
                        --profile-time=60 --screensize=2880x1800 --fullscreen \
                        --enable-glow --enable-bloom --enable-light-shaft --enable-dof \
                        --enable-motion-blur --enable-mlaa --enable-ssao --enable-ibl \
                        --enable-hd-textures --enable-dynamic-lights --anisotropic=16 \
                        --shadows=1024 --numkarts=8 --track=black_forest --render-driver=vulkan

Better reproducibility over random kart laps

I thought it just plays the same pre-recorded ghost replay all the time...

The profile-time option? As far as I know, it should "autoplay" a track for just x seconds, you can also vary the number of karts with numkarts, while the benchmark mode just launches the replay, also disabling FPS limits

EDIT: @kimden fixed description, was misleading
