run.sh makes two launch processes?

[geniot]

Do you know why there are two launchers used: sh and bash?

ark@rg351mp:/roms/native$ ps aux | grep hello-sdl2.exec
ark      18587  0.0  0.0   2048   524 ?        S    14:05   0:00 sh -c /roms/native/run.sh /roms/native/hello-sdl2.exec
ark      18588  1.2  0.3   6464  2824 ?        S    14:05   0:00 bash /roms/native/run.sh /roms/native/hello-sdl2.exec
ark      18705 26.0  3.3 364656 30944 ?        Sl   14:05   0:00 /roms/native/hello-sdl2.exec
ark      19531  0.0  0.0   7684   656 pts/1    S+   14:05   0:00 grep --color=auto hello-sdl2.exec

Also the CPU seems to be overused. You use SDL_RenderPresent but I haven't found anywhere that you use SDL_HINT_RENDER_VSYNC.

Am I wrong here? Thanks.
