Old thread, but I have the same blurry VC panel even though all of the above settings were already implemented. I sim at least half the time in IFR conditions and use ground based nav systems more than GPS, so good quick and precise vision of instruments is important.
The other problem with VC panel is how it moves vertically with aircraft pitch changes. I can't imagine the reason for this. It often makes it very hard to mouse click anything on the panel when it moves like that. I avoid VC panel whenever possible.
I fly the sim with two monitors one above the other. Upper one in VC mode but shifted eyepoint way up (Shift-Backspace) out the roof of the cockpit to make the VC panel go away and get a clear view with no panel. Then I put 2D panel and GPS, radio, etc. on the lower monitor. Even with one monitor, shifting the VC eyepoint above the roof and putting 2D panel below it works well. You can then pan and zoom the scenery view without losing sight of your instruments. Depending on the way the windows are constructed this technique works better on some aircraft sims than others.
As for learning the airspeed by sensing pitch and throttle, that's fine and necessary for real aircraft where you get both of those inputs from the feel of the seat and sound of the engine - but in the sim you only get those inputs from other gauges on the panel, so you may as well be looking at the actual airspeed instead of two other gauges on the panel to estimate airspeed.
