The issue had to do with your monitor having a higher Hz monitor (96 Hz or 144 Hz) then the standard 60 Hz most people have. For some reason the settings I had to control frame rate didn't account correctly for the refresh rate of higher monitors. The only why I could test it was to actually lower the refresh rate of my monitor to 40 Hz. I noticed it was slower then normal game play. I switched some sync settings in Game Maker and found one that didn't slow the game down. Glad this worked!
The FASTER download is suppose to run faster if you are noticing some slow game play (only useful for older computers). The reason it isn't the standard game play is because it is more buggy and takes much longer to compile.
