im running at 60Hz on a 60Hz TV and still seeing the flickering props as well as some flickering at the edge of the screen.

I was a bit unclear, you are certainly right that you get a "disc" of slightly reduced sight (like looking through a light grey plastic film). What you don't see at all are any prop blades or oscillations... I have more than 400 hours stick time IRL myself in various ac accept that Moth ride so even though many here have a lot more I guess it's enough to say I know what a prop looks like from behind...

The problem as I now have identified is that running at 120hz on a fast computer the prop effect freaks out and I see oscillations and flickering blades at 3000 rpm, the same as I see at idle when running at 60hz... It's actually totally unplayable so I have to stick to 60 Hz until they fix it, or give us an option to remove it (and only the prop effect so not the whole anti epilepsy).

I guess the problem is that most don't run at above 100 fps "för real" that I do as they have 60hz monitors that cap them at 60...

well, as I've already told you, I don't think is this.

I am running it at 120 Hz, with vsync and antiepilepsy filter off, and I don't see the hollywood effect on propeller. it must be something else, most probably FPS and/or videocard type (amd/nvidia).

I'll do a recheck tonight when I'll be home.

As I mentioned in the other thread on this subject, the prop effect is far, far too dependent on fps and not totally dependent on prop rpm as it should be. Simply turning to a fps reducing scene (ie towards or away from London/an island in the online maps) will induce flickers in the prop, without any change in rpm - that fact makes each persons impression of the prop different, as we all run different resolutions, detail settings, monitor refresh rates etc. So, I'm guessing we'll see this discussion over and over again.

So, to recap CLOD repeated discussions:
Tracers! - Too thick
Props! - Might be too flickery at low rpm, hard to tell since its different for all of us!
Landing! - Ground too forgiving!
AI! - Disastrously good roll rates, painfully addicted to barrel rolls!

Etc. :) :)

Prop artifacts are definitely fps related on my system, but it's all over the place. The first time I tested it out I was getting intermittent white flickering blades (which I assume isn't a deliberate effect) only when my fps went up as high as they could go, as can be seen in this video at 2:20 - http://www.youtube.com/watch?v=xkH7I4QZB_A

Then the next time I played the game the props had a different, larger, darker, constant kind of rotating flickering at all fps. Hopefully if they fix the blades disappearing altogether behind some types of cloud they'll also address some of these other inconsistencies at the same time.
