my game crashes every time i try to lower the graphics
When adjusting graphics in any game, Ensure the first option you examine is Resolution.
You will butcher any program if a resolution is actually outside of fullscreen capabilities of your gfx card and/or TV/monitor - And usually, either will do it, even if its just outside the range of your display - and the gfx can handle it - HDMI and computer settings often are linked with one or two settings that are "supposed to be for convenience" that often trip up hardware if an error occurs. I've had times where a graphical glitchup occurred (not in this game) - that caused my HDMI capable to stop outputting signal entirely, had to unplug it and plug it back in
Alternatively had times where a resolution shot outside the range of my display, and caused the picture of the game to remain entirely black/blank when partial stability was restored (usually meaning exiting fullscren into window mode) - Even if it started in window mode with picture working just fine, after the fullscreen attempt- it'd be blank on return - requiring the app to be restarted and resolution tweaked
If resolution and other graphical factors aren't the direct issue, Please ignore my reply - I understand there can be other code related breakage specific to this game that could be tripping you/r computer up.
