the car start up seems to stutter every time the page loads but after that its fine. if it helps i play most open world games at medium to low quality for about 50-60 fps. by the way the love this visual style beyond the low poly style.
I guess I can hold off starting the game until the shaders have warmed up and all objects have been allocated in memory. I have the same problem too. I just have to be clever with this to avoid a too long startup time. ;w;
