I found a fix for the download 2. I couldn't download the 64 bit by using opera, but by stopping it every 5 mb and then resuming it after a second or 2 it bypasses this error for some weird reason.

is 64 bit faster and the problem also occured on me but in 32 bit its can only be maximum 4 fps I want it faster lowering the graphics even closing all the audio and all the video settings didnt work
