New demo v1.1 - fixed framerate issues!

I got running Win 8.1 x64 with i5-2500K@4.5GHz and EVGA GF GTX 780 Ti Classified 352.86WHQL (HQ):
min 269 fps
max 783 fps
AVG 518.28 fps
-- No any CPU bottlenecked despite "low" resolution as 1024x768 xD and my "old" CPU!

Try 1920x1080... But please you can test at 1920x1080 because 2560x1080 is invalid for desktop.
