no the game doesn't have a problem....it's probably your computer not being good enough to handle the graphics and such.
when I'm on fulscreen playing 2-4fps, when I play windowed 800x600 15-18 fps and I try the 320x200 windowed 20-30 fps the only problem is I cant play that small. I downloaded 64x and 32x both are the same
Graphics card and CPU ?
Windows 10, 2.17 GHz
um.... i said graphics card and CPU not operating system and GHz
sorry about that, it's 64mb
