c++ – very high gpu usage on a really simple open gl code

this is a simple car crash/race game , and till now i have only drawn the street and tiles and a car and for some reason it’s taking alot of gpu almost 70% on rx 5700xt and even sometime not running properly on other computers, here is the code , i am fairly new to opengl so , i would really appreciate it if someone helped
