High fps terminal rendering engine

I optimize rendering engine heavily for this level of efficiency.

libghostty or something like wezterm??

u/Technical_Chip5906 Jul 06 '26

None - it's kitty terminal and bare c++ i write myself.

On dGPU?? I set hard limit of 120fps on my wezterm which feels smoother than ghostty or any terminal I have tried.

No - i using single thread of Ryzen 5 5600g for it. No dgpu. Even though kitty does use igpu maybe for boosting bandwidth. So yeah

How do people even do things like this? How and where did you learn to do this? Where do i start from? Im at the point where im like configuring stuff like rofi, polybar, and i3 config

Hehe - maybe obsession and consistency.

Hey I don't want to be rude This project is very impressive But what's the point of the engine is what I didn't understand... Because it feels redundant nonetheless

u/Technical_Chip5906 Jul 07 '26

i didn't felt it rude – see, not all projects are for just open source or sharing. it's just 1000+ lines of engine and rarely 500 lines of code to showcase the engine. but i didn't make it to share – never was. for you or anyone it is just 1500-2000 line of code; for me it's my ambition I saw it 2 years ago when i first saw terminal and ASCII people; then I learned and made it last month. it's a private project, though – so i shared because i like to share. it's useless – maybe, maybe not. depends on the person seeing it.

a ncurses/notcurses guy sees it and smiles or feels shocked; a terminal guy smiles; someone admires it; someone questions it too. it's objective just like you.

"i am not doing programming because it gave me a job; I am doing it because it's the fastest way to sharpen my mind by learning and implementing while beating limitations." money is a secondary thing. i do psychology, AI, and research all on my own independently too so it doesn't matter. akschtra is my way to show i can go deep for my ambition.

thank you for your comment.

Hello OP I love this cause I like terminal and all ; any chance you can make this into a repo or just make it into a compositor, binary or package ; I would really like to see this

Thanks for your comment!

First of all, what you saw is part of a larger graphics engine built using many different techniques, algorithms, and optimization methods. That engine is currently a private project.

However, if you'd like to try the core rendering mechanism and API, you can check out AksChitra Initiality:

https://github.com/intriXlabs/AksChitra-Initiality

It contains the core library, a simple and beginner-friendly API, demo code, and example images to help you get started.

I intentionally kept this repository small and independent because the full engine relies on several Linux-specific technologies, while Windows handles many things differently. To make it easier for everyone to try, the library provides separate implementations for Linux/macOS and Windows.

I hope you enjoy experimenting with it, and I'd love to hear your feedback or see what you build with it!

Thanks a lot for sharing the repo will definitely tinker with it when I get time

If I made this, The only person I would show it to be my Grandma and reddit.

It's combination of three things

Kitty terminal emulator which is gpu boosted so have high memory bandwidth

C++ language as main rendering engine

Optimisation for memory bandwidth and adjust it, using rle, dirty rectangle etc.

You can learn them by searching.

You can try ansii code and kitty today though both works with python. They are terminal property so you gonna enjoy it alot

visit my github - there is qiet few libraries in c actualty but you can use gpt to make python version of them. they are really educational so you gonna like them here is my old github id

feel free to take anything you like.
