26 - 28 You are getting there, you just need a little more.
Try one of the following:
- In OPTIONS:AUDIO, disable 16-BIT AUDIO
- In OPTIONS:AUDIO, reduce the MIXING RATE
- In OPTIONS:AUDIO, reduce the CHANNELS
- In OPTIONS:VIDEO, turn on DON'T DRAW TREE LAYER
Now replay MISSION 0, fly past the convoy again,
and check your lowest frame rate against this table
again.
25- You need to get a major burst of speed.
Try one of the following:
- In OPTIONS:VIDEO, Enable DRAW EVERY OTHER FRAME
- In OPTIONS:VIDEO, Enable INTERLACE MODE
Now replay MISSION 0, fly past the convoy again,
and check your lowest frame rate against this table
again.
Once you can fly past the entire convoy in MISSION 0 without ever dropping
below 29 frames per second, you are done. In OPTIONS:VIDEO, turn off
DRAW FRAME RATE. Enjoy the game!
If you can't reliably reach 30 frames per second, try turning off all of the available drawing options and turning down all the available audio options. If the game is still too slow, let us know. It is still quite playable, but a little easier.
In some very heavily populated missions your frame rate may drop below 30 frames per second on slower machines.
