I used SDL2. Not actively working on that project anymore, but I picked it due to requirements - fast startup, low latency, low memory usage, portability anywhere (linux on multiple distros, CPU architectures and multiple rendering backends, any Windows version from XP to 11...). C fits that very well IMO and I don't regret choosing it.
