BenchBurner

about

you're either trying to impress people with your fps, trying to benchmark your pc, or you just like staring at numbers while pretending it's science. no judgment, all three are valid. you're in the right place.

benchburner is an msi afterburner style overlay for minecraft with a built in benchmark recorder. it shows fps, frametime, gpu, cpu and ram in one chunky block, comes with a bundled benchmark world built for repeatable a/b testing, and tells you exactly how a run went. export it to csv and win arguments in discord, or lose them with proof.

if your game runs like a powerpoint after installing 47 performance mods, now you can watch it happen live, with a graph. you're welcome.

client-side only. your server admin never finds out about your 12 fps.

features

• one overlay block: fps, gpu, cpu, ram, frametime graph and benchmark status in a single chunky afterburner panel. every line can be turned off in settings, for when the truth is too much
• fps: current, average, 1% low and 0.1% low (the number your friend with 400 fps begged you not to look at)
• gpu: name, usage, temperature, power draw, fan speed, vram, core and memory clock. read through nvidia-smi or your amd linux driver where they exist, hidden where they don't. intel gets its name and a moment of silence
• cpu: load, clock speed, per core grid, temperature where your system exposes it. on windows, java usually does not. java has trust issues
• frametime graph: a live chart of your game falling apart, free entertainment
• traffic light colors: red, yellow and green on values, with thresholds you set. you will see a lot of red. that's on you
• settings screen: sections with fold chevrons, so it doesn't look like a tax form. left click turns things on, lowers values and cycles colors forward. right click turns things off, raises values and cycles colors back. yes it's intuitive, no you won't read this
• presets: minimal, standard and full, plus custom presets you name and save. share configs through clipboard export and import, because pasting json into discord is its own kind of flex
• overlay toggle key: hide the whole block with one press, show it again with the same press. benchmark recording keeps going while you pretend nothing is happening
• a benchburner button in the top right of the title screen and the esc menu, plus a keybind. nobody should have to dig through a mods folder to find a config screen

keybinds

• R start or stop benchmark
• N export last benchmark again
• K overlay settings
• O hide or show overlay
• B benchmark world

all of them live in the benchburner category in the controls screen. rebind them however you want, i'm not your dad.

benchmark

press R to start a run, press it again to stop. you get average fps, min and max fps, 1% and 0.1% lows and average frametime, in a summary panel and in chat. the full run exports to csv in your game directory with a timestamped name the moment it ends. press N to export the last run again, in case you want to relive it. post it, or delete it and pretend it never happened. i won't tell.

the benchmark world

press B. the mod unpacks a bundled test world into your saves folder if it isn't already there, opens it, and prepares the crime scene: time frozen at noon, no mobs, no weather, no phantoms ambushing a benchmark, no fires spreading. you get dropped at the world spawn every time, the world settles for 5 seconds, then a run records itself for a fixed length, stops, summarizes and exports. 60 seconds by default, adjustable from 10 to 600 in settings.

why do you care? because comparing modpacks needs identical scenes. modpack a in the world, modpack b in the world, same time of day, same spot, same length. bigger number wins. the mod can't stop you from walking a different path, but it removes everything it can remove. the rest is on your honor, which is not a great system, but here we are.

requirements

• minecraft 1.21.11 with fabric loader and fabric api
• java 21
• a pc. any pc. i'm not picky, i've seen your fps

faq

does it hurt my fps?

barely. stats are read on a background thread so the render path stays clean. a performance mod that lags your game would be hilarious, and i refuse to give you that.

why is cpu temperature missing?

some systems, mostly windows, don't let java read it. when it can't be read the stat is hidden. not a bug, java is just shy.

why is my gpu panel half empty?

the mod reads what system tools can read: nvidia-smi on nvidia, sysfs files on amd linux. hidden lines mean the source on your system has nothing to give. i can't make your driver talk. i've tried. it's emotionally unavailable.

my fps is bad, is the mod broken?

no. the mod works perfectly. it is simply telling you the truth. nobody warned you about that part.

can i use this to flex my fps?

absolutely. screenshot it, post it, ruin someone's day. just don't post the 0.1% lows.

can i run this on my potato?

yes. the mod is light. the potato is the problem, and now you'll have the data to prove it.

other versions and forge?

right now it's built for 1.21.11 and fabric only. more versions and loaders are planned once this one proves itself. asking "when" in the comments will not speed it up. i checked.

something is wrong or missing?

open an issue on github with what is off. screenshots help. angry paragraphs don't, but i'll read them anyway.

conclusion

so that's benchburner. it shows your fps, records your runs, and never lies to you, which is more than i can say for most things on the internet.

if you like it, leave a follow or a ko-fi, it helps more than you think. if you hate it, open an issue and tell me why. if your fps is bad, that's not my fault, i just made the graph.

now go benchmark something.

mit. do whatever, just don't ship the bugs back to me as features.
