With a low end card the first thing I would do (did) was to disable vertical sync, I don't like the tearing you get but the gain is more substantal than most other options. With Il2 it is 'on' as standard, so on a nvidia card you need to set it to 'forced off' to disable it. Also 4.09 maps are far more demanding on your system than 4.08 so that should be taken into account when you are configuring your graphics.
