It would be cool if the autor of this plugin can relase soruce code beacuse i found the script crash error after we lost d3d in fullscreen mode. This only happen in Windows 10 not in Win 7 or XP. The solution is switch to window mode before we exit.
Code:
#include <default.c>

var fsaa_maxQualityNonMaskable(); 
var fsaa_eventSky(); 
var fsaa_eventEntities();
var fsaa_eventLost(); 
var fsaa_setQuality(var);

function change_res_fullscreen(){ video_switch(9,0,1);}
function change_res_window(){ video_switch(7,0,2);}

function main(){
	level_load("");
	
	wait(2);
	render_sky = fsaa_eventSky;
	render_entities = fsaa_eventEntities;
	on_d3d_lost = fsaa_eventLost;
	fsaa_setQuality(fsaa_maxQualityNonMaskable());
	
	while(1){
		on_c = change_res_fullscreen; // script crash after we change to fullscreen and press exit
		on_v = change_res_window; // work when we back from fullscreen and press exit
		if (key_f1) {video_switch(6,0,2); wait(1); sys_exit(""); } // the solution is swich in window mode before exit
		wait(1);	
	}
}
