In AMS when pushing PrtScSysRq we will get a Screenshot under main folder BUT WITH A HUGE LAG. In many games I use Fraps for Screenshot with the key PrtScSysRq, it doesn't cause any profomance impact and I set the key on my wheel as well. In game settings(and Controller.ini) , the screenshot key is F12- the steam's key. I could not find the way to edit or disable the PrtScSysRq key for lagging the game. I just want free the key for fraps only screenshot. I don't want change the fraps key setting everytime I start AMS.
Edit: this doesn't work for me, perhaps it gives you a direction for your search? Perhaps when you remove or edit the line in injector.ini ;make screenshot keycode key_screenshot = 44 ; 44 = PRINTSCREEN KeyboardEvent.keyCode
