I play at 1280x768 in IL2. Everyone needs to remember when the game 1st came out, the game's native res was 1024x768. That's what resolution the game was designed for at the time.
If you play at a 16:9 or 16:10 (depending on your monitor) with 1366x768 or 1280x768 (I think those are the 2 for widescreen) and have all your graphics cranked up including max AA/AF I see no difference in graphics quality between that and my monitor's native res of 1920x1200. But!!!!, I see the dots like they were meant to be displayed. Turning your graphics all the way down to try to get an advantage is pretty lame, but playing the game at close to it's native resolution, is not, IMO.
I hope the dot thing isn't a problem anymore either with the majority of people having high res monitors nowadays, but I think I've seen a few screenies that show distant dots in the background so I think we'll be ok
