How to display highest/maximum GPU/CPU load values?

[asdf-Counter-Strike2-ZE]

Hi, how to add to the GPU load or CPU load another value which displays the highest load that was reached?

[asdf-Counter-Strike2-ZE]

I added it myself. This is for the GPU maximum load and it would be similar for anything else like minimum and maximum CPU load: Edit hud_elements.cpp and add

#define CHAR_FAHRENHEIT "\xe2\x84\x89"

auto maximum_gpu_load = 0;

// Cut from https://github.com/ocornut/imgui/pull/2943

[...]

if (HUDElements.params->enabled[OVERLAY_PARAM_ENABLED_gpu_core_clock] || HUDElements.params->enabled[OVERLAY_PARAM_ENABLED_gpu_power]){ ImGui::TableNextRow(); ImGui::TableNextColumn(); ImGui::Text("Maximum"); ImGui::SameLine(0, 1.0f); if(gpu_info.load > maximum_gpu_load) maximum_gpu_load = gpu_info.load; right_aligned_text(text_color, HUDElements.ralign_width, "%i", maximum_gpu_load); ImGui::SameLine(0, 1.0f); ImGui::Text("%%"); ImGui::TableNextRow(); ImGui::TableNextColumn(); }

(too bad quotes ignore spaces and ``` dont allow for making text bold..there's always go to be something haha..probably a reason for it tho)

I use Arch Linux so to rebuild without the .cpp file being overwritten: On first ever use, use normal makepkg -si, then make your edit to the .cpp file, then edit PKGBUILD and comment out:

#source=("git+https://github.com/flightlessmango/MangoHud.git#tag=v$_pkgver"
#        'git+https://github.com/flightlessmango/minhook.git'
#        "https://github.com/ocornut/imgui/archive/v${_imgui_ver}/imgui-${_imgui_ver}.tar.gz"
#        "https://wrapdb.mesonbuild.com/v2/imgui_${_imgui_ver}-1/get_patch#/imgui-${_imgui_ver}-1-wrap.zip")
#sha256sums=('SKIP'
#            'SKIP'
#            'f7c619e03a06c0f25e8f47262dbc32d61fd033d2c91796812bf0f8c94fca78fb'
#            '6d00b442690b6a5c5d8f898311daafbce16d370cf64f53294c3b8c5c661e435f')

then build using makepkg -f -si. You will get error in package_mangohud() so just remove the 2 folders doc and man in /home/USERNAME/PKGBUILD/mangohud/src/common manually before using makepkg -f -si.

The code I added can of course be be fully incorporated into its own function, a configuration can be added and so on. Hope this gets added soon as having this is kinda useful and is easy to add.

Edit I added also an average feature. MangoHud's fps_sampling_period applies it to the one and only FPS value. Now I have two with different sample sizes (I probably could have used some of MH's sampling code for that or C++'s structures). See diff/patch for v0.6.7 with these two changes below. It's not a PR since the patch doesn't follow any quality guidelines.
