From Wiley: If you're hitting them after they drop, that's not defense, that is revenge.
I think the issue you're seeing is from the low resolution of your television. You can try setting AA to see if that helps. You may need to connect to a monitor with higher resolution to fix the problem. The higher resolution textures may not show any difference at your low resolution. For a quick fix to see the fuel state use zoom.
I downloaded the highres pack and installed it but how do I know if it's applied and it's working?
