• verify that FOV is center of screen
• if above is true, find result for missing shots
• find another bottleneck

  • Bitmap.CopyFromScreen
    • Slowest
  • GDI+
    • Supposedly sometimes faster than DirectX
  • DirectX
  • DirectX Hooking
    • Anticheat problems

General loop

• proccess images sequentially, one after another, not thru timers. This way its as fast as possible
• use one thread for capturing and another for analyzing
• reuse bitmap contexts, minimize creating new ones
