X-Plane 10.04r1 HDR FXAA vs. 8x AA (Radeon HD 7970) [VIDEO]

In my HD 7970 travels, I recorded two short videos so users can see a comparison between HDR and non-HDR flying.  This isn’t meant to be a direct comparison per se, but it will show how the HD 7970 is doing overall.  The first video uses HDR with atmosphere scattering and FXAA post process anti-aliasing enabled.  The second video uses 8x anti-aliasing with HDR disabled.

HDR with FXAA post process & atmospheric scattering

Filmed near KLXV airport, direct KDEN.  Aircraft is Twin Otter by X-Hangar.  While performance was so-so and artifacts were present during this trip, the simulator was usable.

Non-HDR with 8x anti-aliasing

Filmed over Lake Michigan after departing KORD.  Aircraft is Challenger 300 by ddenn.  While the 8x anti-aliasing outperformed HDR flying, the simulator froze about twenty minutes into the flight.  Other than that, the simulator was usable, with so-so performance.

I realize it’s apples and oranges to a degree, but which do you think looks better?

    I just posted a critical post about this issue on the xplane.org forum and it got deleted right away.

    That hardens my feeling that LR wants to keep this serious problem from the table, and not discuss it any further !
