DirectX uses specific functions of the gpu.
Of course it does. That's what "hardware accelerated" means ;)
My bad. I mixed it up. Sorry about that.
Well, if it turns out that browsers in general don't reach stable 60 fps yet, it kind of relieves me. I really thought it is just an issue with my pc again.
I don't see why I should buy some expensive hi-end graphic card just to be able to see 60 fps in low resolution canvas-games, when my current equipment is fully capable of doing it. I mean, it even runs flash games with highest demands and sizes solely based on the cpu with stable 30 fps. I expect at least the same power from HTML5.
So I will wait just a little longer. (I don't like google, that's why I won't install chrome, I'll stick to firefox)
