i notice a fews months that a game like lbreakouthd (morphos storage) work only if the option sdl2 on mode opengl sofware
so if when we want play another game with open gl hardware this option is best for games like doom3 and put shaders on in sdl2 too

Not sur to understand... but better leave SDL2 options per default.

You can find menu on all SDL2 app, for example: https://ibb.co/M7PKXFj

HINT RENDER concer only SDL2 renderer (SOFTWARE and ACCELERATED mode), Doom3 uses its own opengl rendering engine (so all RENDER options does not affect this kind of game)

ok for answers beworld
i try another game devolution x (diablo) to see
and i have more frame/seconde with sdl2 hardware actiate than software
to see
thanks
